AI Technical Summary
When handling wafers, the existing metal baskets cause metal particles to occur due to collisions between metals and metals, which fall on the wafer surface, causing product defects.
A non-metallic basket is designed, using a fixed block and fixed groove structure made of non-metallic polyether ether ketone, to reduce direct collision between metal and metal and prevent metal particles from falling on the wafer surface.
By reducing the collision between metals, the generation of metal particles is reduced, and the metal particles are prevented from falling on the wafer surface, improving product quality and operating efficiency.
