Latest Patents

Chih-Yang Li holds a patent for a "Wafering method comprising a plasma etch with a gas emitting wafer holder." This invention aims to reduce edge roll-off during the semiconductor wafering process. The method involves subjecting the wafer to a plasma etch with an edge underetch, achieved through a specially designed wafer holder that emits gas towards the wafer. This gas creates a vortex that draws the wafer closer to the holder's body, allowing the plasma to effectively etch the wafer surface while controlling the etching rate near the edges. As a result, the etch proceeds more slowly at the edges, leading to improved wafer quality.
