Abstract

The invention provides a PECVD (Plasma Enhanced Vapor Deposition) reaction chamber and a support pin for the PECVD reaction chamber, which belong to the technical field of semiconductors. The supportpin for the PECVD reaction chamber comprises a pin core , a pin sleeve coating outside the pin core, and at least one layer of spacer arranged on the bottom parts of the pin core and the pin sleeve, wherein the pin core and parts, corresponding to the pin core and the pin sleeve, of the gaskets are made of conductive materials; and the pin sleeve is made of a non-conductive material. According tothe support pin, the pin core is made of the conductive material, and the pin core and the gaskets are grounded, so that the whole support pin is grounded, the number of serially connected capacitorsof a Pin area can be reduced, the plasma density of the Pin area is improved, and a capacitor difference between the Pin area and a non-Pin area is reduced.

Description

technical field [0001] The present disclosure relates to the technical field of semiconductors, in particular, to a PECVD reaction chamber and a support needle used in the PECVD reaction chamber. Background technique [0002] In the TFT-LCD (Thin Film Transistor Liquid Crystal Display, Thin Film Transistor Liquid Crystal Display English) industry, the support pin Lift Pin is widely used to support the glass substrate. However, due to the use of the supporting pin Pin, it is easy to cause a difference in plasma density between the Pin region and the non-Pin region, which in turn leads to a difference between the film formed in the Pin region and the film formed in the non-Pin region. [0003] In the PECVD (Plasma Enhanced Chemical Vapor Deposition, plasma-enhanced chemical vapor deposition) process, the reactive gas containing the constituent atoms of the film is ionized by microwave or radio frequency to form plasma locally, and the plasma chemical activity is very strong. ...
