First embodiment

Referring to fig. 2A to 2G, fig. 2A to 2F are side views of a first structure to a sixth structure of a package device according to a first embodiment of the present invention, and fig. 2G is a perspective view of the package device according to the first embodiment of the present invention, and the manufacturing method of the package device according to the present invention is combined with fig. 1. As can be seen from the above figures, the package device 1 of the present invention includes a substrate unit 10, a passive unit 11, a conductor unit 12, a package unit 13 and an electrical medium unit 14. The passive unit 11 is disposed on the substrate unit 10. The conductor unit 12 and the passive unit 11 are disposed on the same side of the substrate unit 10 and electrically connected to the passive unit 11. The encapsulation unit 13 covers the passive unit 11 and the conductor unit 12. The electric intermediate unit 14 electrically contacts the conductor unit 12 and is exposed by the encapsulation unit 13.

Specifically, the package device 1 of the present invention can be manufactured through the steps S20 to S24 or the steps S20 to S25 in the manufacturing method of the package device, and in the embodiment, the steps S20 to S24 are taken as an illustration, but not limited thereto. Further, the substrate unit 10 is provided in step S20, and the substrate unit 10 may be made of iron oxide, but not limited thereto. Next, step S21 is performed to form a passive unit 11 on the substrate unit, where the passive unit 11 may be, but is not limited to, an inductor. Then, step S22 is performed again, and the conductor unit 12 is formed on the substrate unit 10, the conductor unit 12 can be adjacent to and electrically connected to the passive unit 11, and the conductor unit 12 can be an electrode, but not limited thereto. Then, step S23 is performed to cover the package unit 13 between the passive unit 11 and the conductive unit 12 to form a package body Z, wherein the package unit 13 may be made of a polymer material, but not limited thereto.

Before step S24, the present invention may print an iron oxide paste on the top surface of the package body Z (i.e., the surface covering the package unit 13), and then polish the top surface and the bottom surface of the package body Z (i.e., the bottom of the substrate unit 10) to thin the substrate unit 10 and expose the conductor unit 12 to the package unit 13. Finally, step S24 is performed again, the package body Z is cut to form a plurality of unfinished products of the package elements 1, and the electric medium unit 14 is formed on the conductor unit 12 of each package element 1 to make a finished product of the package element 1, as shown in fig. 2G. In fig. 2G, (a) and (b) are different patterns that can be made after the package device 1 of the present invention is implemented.

In one preferred embodiment, the substrate unit 10 may include a substrate layer 100 and a planar layer 101 disposed on the substrate layer 100, and the passive unit 11 and the conductor unit 12 are disposed on the planar layer 101. That is, in step S20 of the method for manufacturing a package component of the present invention, the method further includes: step S200: providing a base layer; and step S201: a planar layer is formed on the base layer. Therefore, the package device 1 of the present invention can be manufactured by providing the base layer 100 first, and then forming the flat layer 101 on the base layer 100 by using the photolithography process to form the substrate unit 10. Next, as described above, the passive element 11 and the conductive element 12 are formed on the planarization layer 101. The base layer 100 may be made of iron oxide or ceramic, and the planarization layer 101 may be made of polymer, but not limited thereto.

In another preferred embodiment, the passive unit 11 may include at least one coil 110 and at least one isolation layer 111. At least one coil 110 is disposed on the substrate unit 10, and is adjacent to and electrically connected to the conductor unit 12. At least one isolation layer 111 covers the at least one coil 110 and is adjacent to the conductor unit 12, and the at least one isolation layer 111 is covered by the encapsulation unit 13. In the present embodiment, the coils 110 and the isolation layers 111 are taken as examples, but not limited thereto.

For example, the package device 1 of the present invention can be formed by the step further included in the step S21 of the method for manufacturing the package device to form the passive unit 11 including the coil 110 and the isolation layer 111. That is, the coil 110 is formed on the substrate unit 10 in step S210, and then the isolation layer 111 is formed on the coil 110 in step S211, so as to form the passive unit 11 on the substrate unit 10. In addition, by sequentially repeating the steps S210 and S211, a plurality of coils 110 and a plurality of isolation layers 111 can be stacked.

It is noted that in the process of forming the passive unit 11 by sequentially forming the coil 110 and the isolation layer 111, the conductive unit 12 can be formed simultaneously. That is, in step S210, some of the conductor units 12 may be formed together, and in step S211, some of the conductor units 12 may be formed again together. Furthermore, the steps of forming the passive element 11 and the conductive element 12 can be combined with the photolithography process.

However, the package device and the method for fabricating the same of the present invention are not limited to the above examples.

Second embodiment

Referring to fig. 3A to 3M, fig. 3A to 3J are side views illustrating a first structure to a tenth structure of a package device according to a second embodiment of the present invention, and fig. 3K to 3M are side views illustrating a first perspective view to a third perspective view of a package device according to a second embodiment of the present invention, and are matched with the method for manufacturing the package device according to the present invention, fig. 1, and fig. 2A to 2G. As shown in the drawings, the package device in this embodiment has similar operations to the same components of the package device in the first embodiment, and therefore, the description is omitted, and it should be noted that, in this embodiment, the substrate unit 10 includes a base layer 100 and a flat layer 101 located on the base layer 100, the passive unit 11 is located on the flat layer 101, and the conductor unit 12 is located on the base layer 100 and connected to the base layer 100.

Specifically, the difference between the present embodiment and the first embodiment is that the conductor unit 12 of the present embodiment is located on the substrate layer 100 and connected to the substrate layer 100. Therefore, the package component 1 of the present invention can provide the base layer 100 first by the manufacturing method of the package component, and then form the flat layer 101 with a slightly smaller area than the base layer 100 on the base layer 100 by using the photolithography process technology to manufacture the substrate unit 10, the passive unit 11 can be formed on the flat layer 101, and the conductor unit 12 can be formed on the base layer 100 not covered by the flat layer 101 to connect with the base layer 100.

In addition, in the present embodiment, it is preferable to have a plurality of embodiments, one of which is shown in fig. 3A to 3G, and the other is shown in fig. 3A to 3D (a) and then fig. 3H to 3J. Further, the difference between the two embodiments is that the conductive pillars formed by the conductive elements 12 can be three or four, as shown by the dashed boxes C1 in fig. 3D and C2 in fig. 3H. When the number of the conductive pillars formed by the conductive elements 12 of the package body Z is four (as shown in the dashed box C1 in fig. 3D), the package device 1 can be made as shown in fig. 3K (a), and the first electrode layer 140 and the second electrode layer 141 can be located at the long sides or corners. When there are three conductive pillars formed by the conductive elements 12 of the package body Z (as shown in the dashed box C2 in fig. 3H), the package device 1 is manufactured as shown in fig. 3K (b), fig. 3L and fig. 3M, and the first electrode layer 140 and the second electrode layer 141 can be located at the long sides or corners.

In this embodiment, after step S23, in addition to printing the iron oxide glue on the top surface of the package body Z and polishing the top surface and the bottom surface of the package body Z (i.e., the bottom of the substrate unit 10), the electrode layer 3 may be sputtered after polishing the top surface of the package body Z, as shown in fig. 3F. Then, step S24 or step S25 is performed again to manufacture the package component 1.

It should be noted that the package component 1 of the present embodiment can be manufactured by steps S20 to S24 or steps S20 to S25 in the manufacturing method of the package component, wherein steps S20 to S24 are the same as those of the first embodiment, and therefore, are not described in detail herein; since the difference between the step S25 and the step S24 is only the sequence of the steps of forming the electrical media unit and cutting the package body, it is not described in detail herein.

However, the package device and the method for fabricating the same of the present invention are not limited to the above examples.

Third embodiment

Referring to fig. 4, fig. 4 is a schematic side view of a package device according to a third embodiment of the present invention, and the package device manufacturing method of the present invention is combined with fig. 1 and fig. 2A to 3I. As shown in the figures, the package component in this embodiment is similar to the same components of the package components in the previous embodiments, and is not repeated herein, and it is worth noting that in this embodiment, the conductor unit 12 includes at least one first conductive member 120 and at least one second conductive member 121 located on the substrate unit 10, and the at least one first conductive member 120 and the at least one second conductive member 121 are electrically connected to the passive unit 11; the at least one first conductive member 120 and the at least one second conductive member are both partially covered by the package unit 13, the at least one first conductive member 120 has a plurality of first contact portions 120A, the at least one second conductive member 121 has a plurality of second contact portions 121A, and the electrical media unit 14 is electrically connected to the plurality of first contact portions 120A and the plurality of second contact portions 121A.

For example, the conductor unit 12 of the present invention further includes at least one first conductive member 120 and at least one second conductive member 121, wherein the at least one first conductive member 120 may have a plurality of first contact portions 120A, and the at least one second conductive member 121 may also have a plurality of second contact portions 121A. That is, the package component 1 of the present invention can further include the step S220 (forming at least one first conductive member and at least one second conductive member on the substrate unit, the at least one first conductive member and the at least one second conductive member being electrically connected to the passive unit) on the substrate unit 10 by the step S22 of the manufacturing method of the package component, and the first conductive member 120 and the second conductive member 121 on the substrate unit 10. Next, step S23 is performed to cover the package unit 13 on the first conductive member 120 and the second conductive member 121. As described in the foregoing embodiment, in the process of forming the coil 110 and the isolation layer 111, a portion of the first conductive member 120 and a portion of the second conductive member 121 may be formed together, and then the first conductive member 120 and the second conductive member 121 may be formed in a stacked manner. Moreover, the portions of the first conductive member 120 and the second conductive member 121 covered by the encapsulation unit 13 of the present invention may further form a pillar structure.

Then, after step S23, an iron oxide paste may be printed on the top surface of the package body Z, and the top surface and the bottom surface (i.e., the bottom of the substrate unit 10) of the package body Z may be ground, so that the first contact portions 120A of the first conductive member 120 and the second contact portions 121A of the second conductive member 121 may be exposed out of the package unit 13. Finally, step S24 or step S25 is performed to cut the package body Z and form the electrical media unit 14 on the first contacts 120A and the second contacts 121A. The electrical medium unit 14 includes a first electrode layer 140 and a second electrode layer 141, and the first electrode layer 140 and the second electrode layer 141 respectively cover the top surface and the side edge of the package device 1.

However, the package device and the method for fabricating the same of the present invention are not limited to the above examples.
