Technical Field

The present invention relates to a rotary evaporation source in which a plurality of evaporation source units rotate, and a vapor deposition apparatus.

Background

Conventionally, there is known an evaporation source configured such that an evaporation source unit for evaporating a material can be changed by rotatably providing a plurality of evaporation source units. Here, a pipe for circulating the cooling liquid and an electric wire for supplying electric power are connected to each of the plurality of evaporation source units. As a method for installing a plurality of pipes and electric wires while allowing a plurality of evaporation source units to rotate, a technique using a rotary joint is known. However, in this system, since a rotation mechanism is provided at a connection portion of the piping or the like, there is a problem that it is difficult to eliminate leakage of the coolant.

In contrast, a rotary evaporation source is known in which a rotary table for rotating an evaporation source unit is alternately rotated in each of forward and reverse directions for 1 cycle. In this aspect, the connection portion between the pipe (first linear member) and the electric wire (second linear member) is fixed, and since no rotation mechanism is provided, there is almost no problem such as leakage of the coolant. However, in this method, the connection portion between the pipe and the wiring and the turntable moves as the turntable rotates. Therefore, if the arrangement space of the piping and the wiring is narrow, the piping and the wiring may be entangled or a connection portion between them and the turntable may be obstructed.

Detailed Description

Hereinafter, a mode for carrying out the present invention will be described in detail by way of example based on the embodiments with reference to the accompanying drawings. However, unless otherwise specified, the dimensions, materials, shapes, relative arrangement, and the like of the constituent components described in the embodiments do not mean that the scope of the present invention is limited to these.

(example 1)

An evaporation source and a vapor deposition device according to embodiment 1 of the present invention will be described with reference to fig. 1 to 4.

[ vapor deposition apparatus ]

A vapor deposition device including an evaporation source according to the present embodiment will be described with reference to fig. 1 and 2. Fig. 1 is a schematic configuration diagram of a vapor deposition device including an evaporation source according to embodiment 1 of the present invention. Fig. 1 is a cross-sectional view of a vapor deposition device. Fig. 2 is an internal configuration diagram of a vapor deposition device including an evaporation source according to embodiment 1 of the present invention, and shows a schematic configuration in which the inside of a chamber of the vapor deposition device is viewed from above.

The vapor deposition apparatus 1 includes a chamber 10 whose interior is evacuated (reduced-pressure atmosphere) by a vacuum pump 20, and a plurality of evaporation sources 100 disposed inside the chamber 10. The evaporation source 100 heats a material (for example, metal (silver or the like)) of a substance deposited on the substrate 30 to evaporate or sublimate the material. The substance evaporated or sublimated by the plurality of evaporation sources 100 is attached to the substrate 30 disposed inside the chamber 10, thereby forming a thin film on the substrate 30. In the illustrated example, 5 evaporation sources 100 are provided, but the number of evaporation sources 100 is not limited. An evaporation source baffle plate 40 that can open and close the upper side of the evaporation source 100 is provided above the plurality of evaporation sources 100 in the vertical direction. In fig. 2, the evaporation source barrier 40 shown by a solid line shows a state in which the evaporation source 100 is opened upward and the substance evaporated or sublimated from each evaporation source 100 can move toward the substrate 30. In fig. 2, an evaporation source shutter 40X shown by a broken line indicates a state in which the material to be vapor-deposited is blocked by blocking the upper side of the evaporation source 100, and the vapor deposition onto the substrate 30 is stopped.

The plurality of evaporation sources 100 are fixed to positions of a plurality of mounting holes 11a formed in the bottom plate 11 of the chamber 10, respectively. Further, a cooling liquid circulation device 300 as a first device and a power source 400 as a second device are provided below the floor of the floor 200 where the chamber 10 is provided. Hereinafter, for convenience of explanation, the floor surface on which the coolant circulation device 300 and the power source 400 are installed will be referred to as a first floor surface F1, and the floor surface on which the chamber 10 is installed will be referred to as a second floor surface F2. Further, a plurality of first pipes L11 as first linear members extending from the coolant circulation device 300 provided on the first floor F1 are connected to the respective evaporation sources 100. Further, a plurality of first wires L21 as second linear members extending from the power source 400 provided on the first floor F1 are also connected to the respective evaporation sources 100. The plurality of first pipes L11 and the first wiring L21 are provided so as to pass through the through-holes 210 formed in the floor panel 200.

Here, the floor 200 is a floor 200 of a building such as a factory, and a beam or the like is provided inside the floor. Therefore, the through-hole 210 cannot be formed at a free position. Therefore, the first pipe L11 and the first wiring L21 may have to be greatly routed depending on the position where the vapor deposition device 1 is disposed. In particular, when the vapor deposition device 1 is downsized, the space between the chamber 10 and the floor 200 becomes narrow, and the arrangement space of the first pipe L11 and the first wiring L21 becomes narrow. Accordingly, the first pipe L11 and the first wiring L21 may be bent at a substantially right angle below the evaporation source 100. The first pipe L11 is a tubular member made of a resin material or the like.

[ Evaporation Source ]

The evaporation source 100 of the present embodiment will be described in more detail with reference to fig. 3 and 4 in particular. Fig. 3 is a plan view of an evaporation source according to an embodiment of the present invention. In fig. 3, a part of each member is shown in a perspective view for easy understanding of the structure. In the figure, the broken line is a perspective part. Fig. 4 is a schematic cross-sectional view showing an installation state of an evaporation source according to an embodiment of the present invention. The sectional view of the evaporation source in fig. 4 corresponds to the AA sectional view in fig. 3.

The evaporation source 100 includes a fixed stage 110 fixed to a position of a mounting hole 11a formed in the bottom plate 11 of the chamber 10, a rotary stage 120 rotatably provided on the fixed stage 110, and a plurality of evaporation source units 150 provided on the rotary stage 120.

The fixed base 110 includes a cylindrical body portion 111, an outward flange portion 112 provided at an upper end portion of the body portion 111 in the vertical direction, and an inward flange portion 113 provided at a lower end portion of the body portion 111 in the vertical direction. A cover 114 having an opening 114a is fixed to the body 111 vertically upward. The cover 114 can move only the substance evaporated or sublimated from the evaporation source unit 150 located directly below the opening 114a toward the substrate 30, and can function as a blocking member for the substance evaporated or sublimated from the other evaporation source units 150. Thus, since the substance moves only from a predetermined position toward the substrate 30, a desired film can be formed on the substrate 30 with high accuracy.

The rotary table 120 includes a first cylindrical portion 121, a bottom plate portion 122 provided at a lower end of the first cylindrical portion 121, a second cylindrical portion 123 provided below the bottom plate portion 122, a gear portion 124 provided below the second cylindrical portion 123, and an inward flange portion 125 provided below the gear portion 124. The first cylindrical portion 121 and the second cylindrical portion 123 are concentrically disposed, and the latter is smaller in diameter than the former. The evaporation source 100 is provided with a bearing 140 for allowing the rotation stage 120 to rotate relative to the fixed stage 110. The bearing 140 is fixed on the inner ring side between the second cylindrical portion 123 and the gear portion 124 of the turntable, and on the outer ring side to the tip of the inward flange 113 of the fixed base 110.

Further, a motor 130 is fixed to the outward flange portion 112 of the fixing base 110. A gear 131 fixed to the rotation shaft of the motor 130 meshes with a gear portion 124 provided in the rotary table 120. Thus, when the rotation shaft of the motor 130 rotates, the gear portion 124 rotates via the gear 131, and the rotation table 120 rotates.

A gasket G for sealing a gap between end surfaces between the outward flange portion 112 and the bottom plate 11 of the chamber 10 is provided on the upper surface side of the outward flange portion 112 of the fixed base 110. Further, a packing P is provided between the outer peripheral surface of the second cylindrical portion 123 of the turntable 120 and the tip of the inward flange 113 of the fixed base 110. The gasket P is provided slidably with respect to at least one of the outer peripheral surface of the second cylindrical portion 123 and the front end of the inward flange portion 113 of the fixed base 110, and has a function of sealing an annular gap therebetween. By providing the gasket G and the packing P as described above, the space outside the fixed base 110 can be maintained in the atmospheric state (a) by the evacuation operation by the vacuum pump 20, and the inside of the chamber 10 can be brought into a vacuum (reduced pressure atmosphere) state (V).

Further, a plurality of evaporation source units 150 fixed to the bottom plate portion 122 are provided inside the first cylindrical portion 121 of the turntable 120. Each of the plurality of evaporation source units 150 includes: a crucible 151 for accommodating a material of a substance deposited on the substrate 30; a housing 152 for accommodating the crucible 151; and a heater 153 for heating the crucible 151. Further, a flow path 152a through which a coolant for cooling the crucible 151 flows is provided inside the housing 152. The flow path 152a also functions as a cooling member for cooling the crucible 151.

In the evaporation source 100 configured as described above, the crucible 151 of the evaporation source unit 150 is heated by supplying power to the heater 153 of the evaporation source unit 150 located directly below the opening 114a of the cover 114. Thereby, the material in the crucible 151 is evaporated or sublimated, and vapor deposition is performed on the substrate 30 through the opening 114 a. Then, at a proper timing (such as when the material disappears), the evaporation source unit 150 for vapor deposition can be replaced by rotating the rotary table 120 by the motor 130. Therefore, the rotary evaporation source 100 of the present embodiment can perform vapor deposition continuously for a long time.

Here, in the evaporation source 100 of the present embodiment, a rotary joint method is not employed as a method of providing a plurality of pipes and electric wires while allowing the plurality of evaporation source units 150 to rotate by the rotary table 120. That is, in the evaporation source 100 of the present embodiment, the turntable 120 is alternately rotated 1 cycle in each of the forward direction and the reverse direction. Hereinafter, the configuration of the pipe as the first linear member and the wiring as the second linear member will be described in more detail.

[ Structure of first linear member (piping) and second linear member (wiring) ]

As described above, the plurality of first pipes L11 as the first linear members extending from the coolant circulation device 300 installed on the first floor F1 and the plurality of first wires L21 as the second linear members extending from the power supply 400 are connected to the evaporation source 100. The first pipe L11 is a pipe for supplying and discharging the coolant circulating through the flow paths 152a provided in the evaporation source units 150, respectively. The first wiring L21 is a wire for supplying electric power to the heater 153. The plurality of first pipes L11 are connected to second pipes L12 connected to the flow paths 152a provided in the housings 152 of the evaporation source units 150, respectively, by first connection portions 160, respectively. The plurality of first wires L21 are connected to second wires L22 connected to the heaters 153 provided in the evaporation source units 150, respectively, via second connection portions 170, respectively. The second connection portion 170 is a connector for connecting wires to each other.

Here, the arrangement of the first connection unit 160 and the second connection unit 170 is preferably set as low as possible from the viewpoint of connection work and maintenance. However, the first connecting portion 160 has to be provided in the bottom plate portion 122. This is because a passage through which the coolant flows has to be formed in the bottom plate portion 122 that separates the region in the vacuum (reduced pressure atmosphere) state (V) from the region in the atmospheric state (a). In contrast, in the case of the electric wiring, since there is no such restriction, the second connection portion 170 is provided below the inward flange portion 125. As described above, the plurality of first connection portions 160 are provided at positions above the plurality of second connection portions 170 in the vertical direction. The plurality of first connection portions 160 are provided at positions closer to the rotation center side of the turntable 120 than the plurality of second connection portions 170 so that the plurality of first pipes L11 and the plurality of first wires L21 are less likely to be entangled.

However, as described above, the first pipe L11 and the first wire L21 may be bent substantially at right angles below the evaporation source 100 depending on the positional relationship between the vapor deposition device 1 and the through-hole 210 formed in the floor panel 200. Therefore, in such a case, when no countermeasure is taken, there is a possibility that the first pipe L11 gets entangled with the first wiring L21 or the first pipe L11 collides with the second connection unit 170 (connector) and obstructs the second connection unit 170 when the turntable 120 rotates. For example, the electrical connection failure may be caused.

Therefore, the evaporation source 100 of the present embodiment includes the guide member 180 that partitions the plurality of first pipes L11 and the plurality of second connection portions 170. The guide member 180 is fixed to the bottom surface of the inward flange 125 of the turntable 120. The lower end of the guide member 180 is located below the lower end of the second connection portion 170 in the vertical direction. More specifically, the guide member 180 is configured by a cylindrical member (in the present embodiment, a cylindrical member) provided inside so that the plurality of first pipes L11 pass therethrough and outside so that the plurality of second connecting portions 170 are arranged. Here, when the rotary table 120 rotates, the guide member 180 and the first pipe L11, and the guide member 180 and the first wire L21 are slidable. Therefore, in order to reduce the sliding resistance and to make it difficult to wear, the guide member 180 is preferably made of a resin material (for example, nylon monomer, PA6(6 nylon)) as a sliding material. Further, it is also preferable to provide a fluorine coating layer on the surface of the guide member 180 by performing fluorine processing on the surface of the guide member 180.

[ Excellent points of the evaporation source and the vapor deposition device in the present example ]

According to the evaporation source 100 of the present embodiment, the plurality of first pipes L11 and the plurality of second connection portions 170 are partitioned by the guide member 180. Therefore, the plurality of first pipes L11 can be prevented from being entangled with the plurality of first wires L21. Further, since the first pipe L11 and the second connection portion 170 can be prevented from colliding with each other, the second connection portion 170 can be prevented from being damaged. This can reduce the arrangement space of the first pipe L11 and the first wire L21, and thus can cope with the miniaturization of the vapor deposition device 1. In addition, the degree of freedom in the arrangement of the vapor deposition device 1 also increases.

(example 2)

Fig. 5 shows embodiment 2 of the present invention. In this embodiment, a configuration relating to the arrangement of the first connection portion and the second connection portion is shown which is different from the case of embodiment 1 described above. Since other configurations and operations are the same as those in embodiment 1, the same components are denoted by the same reference numerals, and descriptions thereof are omitted.

Fig. 5 is a schematic cross-sectional view showing an installation state of an evaporation source in example 2 of the present invention. The overall configuration of the vapor deposition device is as described in embodiment 1 above, and therefore the description thereof is omitted. The evaporation source has the same basic configuration as that described in embodiment 1 above, except for the configuration of the first connection portions 160 and the second connection portions 170, and therefore, the description thereof is omitted.

In the present embodiment, a plurality of first pipes L11 as first linear members extending from the coolant circulation device 300 installed on the first floor F1 and a plurality of first wires L21 as second linear members extending from the power supply 400 are connected to the evaporation source 100. The first pipe L11 is a pipe for supplying and discharging the coolant circulating through the flow paths 152a provided in the evaporation source units 150, respectively. The first wiring L21 is a wire for supplying electric power to the heater 153. The plurality of first pipes L11 are connected to second pipes L12 connected to the flow paths 152a provided in the housings 152 of the evaporation source units 150, respectively, by first connection portions 160, respectively. The plurality of first wires L21 are connected to second wires L22 connected to the heaters 153 provided in the evaporation source units 150, respectively, via second connection portions 170, respectively. The second connection portion 170 is a connector for connecting wires to each other.

As described in embodiment 1, it is preferable that the first connection portion 160 and the second connection portion 170 are disposed at positions as low as possible, but the first connection portion 160 has to be disposed on the bottom plate portion 122. In contrast, in the case of the electric wiring, there is no such restriction. Therefore, in the present embodiment, a hole through which wiring passes is provided in the center of the bottom plate portion 122, and a bottomed cylindrical portion 122a is provided below the hole. A second connection portion 170 is provided below the bottom of the bottomed cylindrical portion 122 a. As described above, the plurality of first connection portions 160 are provided at positions above the plurality of second connection portions 170 in the vertical direction. The plurality of second connection portions 170 are provided at positions closer to the rotation center side of the turntable 120 than the plurality of first connection portions 160, so that the plurality of first pipes L11 and the plurality of first wires L21 are less likely to be entangled.

The evaporation source 100 of the present embodiment includes a guide member 180 that partitions the plurality of first pipes L11 and the plurality of second connection portions 170. The guide member 180 is fixed to the bottom surface of the bottomed cylindrical portion 122a of the turntable 120. The lower end of the guide member 180 is located below the lower end of the second connection portion 170 in the vertical direction. More specifically, the guide member 180 is configured by a cylindrical member (in the present embodiment, a cylindrical member) provided so that the plurality of first pipes L11 pass through on the outside and the plurality of second connecting portions 170 are disposed on the inside. The material and the like of the guide member 180 are as described in embodiment 1 above.

The evaporation source 100 of the present embodiment configured as described above can also provide the same effects as those of the case of embodiment 1.

(others)

In the above-described embodiments 1 and 2, the configuration in the case where the first pipe L11, the first connection portion 160, the first wiring L21, and the second connection portion 170 are provided in plural numbers respectively for one evaporation source 100 is shown. However, the present invention also includes a case where only one first pipe L11 and one first connection section 160 are provided for one evaporation source 100, and a case where only one first wiring L21 and one second connection section 170 are provided for one evaporation source 100. That is, the second pipes L12 connected to the evaporation source units 150 can be collected into one pipe (collection pipe) inside the turntable 120. In this case, only one first pipe L11 and one first connection portion 160 may be provided for one evaporation source 100. Similarly, the second wires L22 connected to the evaporation source units 150 can be collected into one wire inside the turntable 120. In this case, only one first wiring L21 and one second connection portion 170 may be provided for one evaporation source 100.
