Problems solved by technology

[0003] In order to improve the uniformity and consistency of the temperature and atmosphere during the wafer reaction process, the wafer needs to be kept rotating. The existing slide table is prone to disturbance and vibration during the rotation process, which will easily lead to inaccurate positioning of the wafer, which is not conducive to the overall stability of the wafer. Process uniformity and consistency
In addition, the structure of the moving parts of the existing slide table is complex, and the friction between the moving parts tends to produce particles, which affects the cleanliness of the process chamber

An inverted V-shaped limit ring groove is arranged on the lower surface of the wafer carrier ring. The upper end of the support cylinder is embedded into the V-shaped limit ring groove. The slide holder provided by the invention has the advantages of simple structure, accurate wafer positioning, uniform process, good consistency and the like.

Description

technical field [0001] The invention relates to rapid heat treatment equipment used in semiconductor manufacturing process, in particular to a chip loading table used for rapid heat treatment equipment. Background technique [0002] Rapid thermal processing (hereinafter referred to as RTP) process is to reduce the thermal budget of the process by shortening the time that the wafer stays in the thermal field through rapid temperature rise. RTP technology was originally developed for the annealing process after ion implantation, but due to its very fast heating and cooling The advantages of high speed, shorter process time and smaller cavity volume have been widely used in advanced semiconductor manufacturing processes, and have become the mainstream technology for deep submicron semiconductor wafer heat treatment processes. It is used for ultra-shallow junction advanced The advantages of device and large-size wafer manufacturing process are more obvious. The key applications ...
