Float Zone Silicon Wafers

Float Zone Silicon Wafers

PAM XIAMEN offers Float Zone Silicon Wafers, they use FZ Silicon substrates instead of  Czochralski grown silicon.

Or simply put, Float Zone Si is most ly used low volume applications that require high-efficiency while CZ Silicon is used for high volume, less expensive applications.

2. FAQ for Float Zone Silicon Wafer

Q: We would like to make these silicon wafers alkali etched, but you remark “shiny etched” as the screenshot, what do you mean of it?

A: To get a shiny etched surface the silicon wafers shall be acid etched. The acid etching leads to the nice shiny surface (almost like the polished wafer surface), the alkaline etching leads to a matt surface.
