Silicon Wafer Manufacturing Process

The stock removal process removes a very thin layer of silicon and is necessary to produce a wafer surface that is damage-free. On the other hand, the final polish does not remove any material. During the stock removal process, a haze forms on the surface of the wafer, so an extra polishing step gives the wafer a mirror finish.Silicon Wafer Processing - National Chiao Tung University2020-4-23 · Silicon Wafer Processing Dr. Seth P.
