With a total of 2 patents to his name, Yamamoto's work has implications for various applications in electronics.

Latest Patents

Yamamoto's latest patents focus on a method of etching metallic thin films on thin film resistors. In this innovative process, an aluminum (Al) film is formed on a barrier metal that covers a thin film resistor, creating a first opening. A photo-resist is then applied to the Al film and within the opening, which is patterned to create a second opening. This second opening has a smaller area than the first and is designed to expose the barrier metal. The etching of the barrier metal occurs through this second opening, preventing under-cutting by etching from an inner portion more than the opening end of the first opening.
