Latest Patents

Tadashi Denda holds a patent for a "Method for manufacturing single-side mirror surface wafer." This patent describes a process where the surface of a semiconductor wafer, which has been lapped, is ground to remove damage caused during lapping. This process increases the flatness of the wafer surface. Following this, the wafer undergoes composite etching, and both surfaces are polished. The rear surface is slightly polished to achieve a single-side mirror surface wafer, which has a notable difference between the front and rear surfaces. This method allows for the production of a wafer with higher flatness compared to traditional acid or alkali etching methods.
