Latest Patents

Kenji Hiwa holds a patent for a method for forming a Cu film and a storage medium. This method involves the formation of a CVD Cu film on a CVD-Ru film that is applied to a wafer. The process includes loading the wafer into a chamber and introducing a vapor-state film-forming source material. This source material, Cu(hfac)TMVS, is a copper complex with a higher vapor pressure than the by-product Cu(hfac) produced during film formation. The method ensures that the pressure within the chamber is controlled to facilitate the desorption and diffusion of Cu(hfac) adsorbed on the surface of the CVD Ru film.
