Manufacturing Ultra-Thin Silicon Wafers
Producing ultra-thin silicon wafers requires precision grinding, chemical mechanical polishing (CMP), stress-relief processing, and advanced handling techniques. Modern manufacturing methods produce mirror-polished surfaces with extremely low total thickness variation (TTV), allowing the wafers to be used in demanding semiconductor applications.
Depending on the application, wafers can be supplied with custom thicknesses, orientations, dopant types, resistivity ranges, oxide coatings, and single-side or double-side polished surfaces.
