Title: Rui Toyota: Innovator in Semiconductor Technology
Introduction
Rui Toyota is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of semiconductor technology, holding a total of 3 patents. His innovative work focuses on enhancing the reliability and efficiency of semiconductor devices.
Latest Patents
One of Rui Toyota's latest patents describes a semiconductor device featuring a copper fuse designed to prevent damage to the silicon substrate beneath it. This is achieved by utilizing a light-absorbing layer made from a material with a higher light absorption coefficient than that of the copper wiring layer. The design allows the copper fuse to be blown using a conventional infrared laser beam while protecting the underlying silicon substrate from potential damage caused by visible wavelength laser exposure.
Another patent involves a semiconductor device built on a silicon substrate, where a silicon oxide film is formed. A BPSG film is then applied, followed by a protective silicon oxide film that does not contain phosphorus and has a thickness of at least 1 µm. This innovative structure prevents corrosion of the fuse, resulting in a semiconductor device with highly reliable metal interconnections.
