Latest Patents
Daigo Shitabo's latest patents include a wet etching method and a wet etching system. The wet etching method involves an etchant supply step, where an etchant is supplied from a nozzle to the surface of a workpiece. This is followed by an etching step, where the etchant remains on the surface to perform the etching. Finally, an etchant removal step is conducted to eliminate any remaining etchant from the etched surface. This process is repeated multiple times to ensure precision and quality in the etching results. His second patent, the gettering layer forming method, includes a coating step where a solution of metal salt is applied to the back side of a wafer. After coating, the wafer is heated to diffuse the metal salt, forming a gettering layer that enhances the wafer's performance.
