Problems solved by technology

However, in this prior art, when the base is supported by a plurality of support plates, it is impossible to know whether the base in the vacuum chamber is evenly supported by each support plate, that is, it is impossible to know the supported base. Is there a skewed state, so there is still a problem of poor film quality

Abstract

The invention relates to a device for positioning and supporting a base lifting a bearing base plate applied in a cavity of vacuum equipment. The device holds and positions the base from the side surface of the base by utilizing a side positioning and supporting mechanism, thereby avoiding the position deflexion of the base in the cavity of the vacuum equipment. The side positioning and supporting mechanism and the base form a freely supported beam supporting structure so as to improve the large-area load suspension distortion of the edge of the base and enable the large-area base plate to bearranged on the base to maintain the flatness or adjust the horizontal benefit. The invention can obviously improve the evenness of the thin film deposition thickness of the large-area base plate when being applied to plate the large-area base plate.

Description

technical field [0001] The invention relates to a positioning support technology, in particular to a base positioning support device for lifting and lowering a substrate in a cavity of a vacuum equipment. Background technique [0002] Industries such as semiconductors, thin-film transistor liquid crystal displays (TFT LCD, Thin-Film Transistor Liquid Crystal Display), and thin-film solar cells have high commonality in terms of technology, materials, and equipment. At the same time, with the increasing area of ​​products, the area of ​​substrates such as silicon thin-film solar cell modules and LCD TVs that are fed into the coating equipment also increases. Therefore, whether in chemical vapor deposition (CVD, Chemical Vapor Deposition) or physical vapor deposition (PVD, Physical Vapor Deposition) coating equipment, the large-area substrate receiving base (Susceptor) for large-area coating has become a necessary component . [0003] At the same time, especially in the appli...
