Latest Patents

Yoshida holds 1 patent for a method of producing semiconductor devices. This patent describes a process where the surface of a barrier layer, interposed between a silicon substrate and aluminum wiring, is oxidized through heat treatment. The oxidation occurs at temperatures ranging from 350 to 450 degrees Celsius in an atmosphere similar to air or through immersion in an oxidizing chemical. This process forms an oxide film on the surface, which inhibits interdiffusion between the silicon substrate and aluminum wiring, as well as reactions between the aluminum wiring and the barrier layer. The oxide film is formed at atmospheric pressure, ensuring it is not excessively oxidized even when exposed to air at high temperatures. This innovation allows for the reproducible formation of an oxide film with specific thickness and properties that produce the tunnel effect.
