Technical Field

The invention relates to the technical field of substrate pretreatment, in particular to a pretreatment device for a substrate.

Background

In the production process of products such as solar cells, liquid crystal display screens and the like, a workpiece which is used for carrying a plurality of silicon wafers for process coating or is called a substrate is subjected to process coating. The substrate is generally a thin plate-like object having a thickness dimension smaller than the web dimension, and a complete process is completed.

Generally, there are different temperature requirements on the substrate at different stages of the cell production process. For example, in a conventional PECVD coating process, the temperature of the process and the process chamber is usually maintained above 200 ℃, while the temperature of the substrate in the ambient atmosphere is generally only about 20 ℃. At this time, if the substrate can be reasonably preheated, the temperature of the substrate is raised to a certain value, so that the thermal stress and thermal deformation of the substrate caused by large temperature difference after the substrate is sent into the process chamber can be reduced, the temperature uniformity of the substrate can be effectively improved, the substrate can be prevented from being cracked or damaged, and the process effect can be improved.

For example, after a certain process is completed, the substrate needs to be taken out of the equipment, and at this time, the substrate will have a high temperature close to about 200 ℃, and if the substrate is taken out of the equipment directly, the substrate is not only dangerous at high temperature, unfavorable for operation and easy to cause accidents, but also easily causes cracks of a process film, cracks or damages of the substrate and the like due to thermal stress and thermal deformation caused by a large temperature difference when the substrate is directly exposed to the atmospheric environment at high temperature. In addition, the high-temperature substrate is easy to react with oxygen, moisture and the like in the atmosphere to directly influence the process result. Therefore, it is necessary to cool the substrate reasonably and take it out of the apparatus after the process.

In view of the above situation, in the prior art, a preheating chamber or a cooling chamber is often added to a vacuum apparatus to achieve a temperature adjustment function, or temperature control and a loading chamber may be combined together. However, in either of the above-mentioned methods, it is necessary to add a separate transfer chamber between the loading chamber and the process chamber, which results in an increase in the footprint of the apparatus.
