Title: Takeyuki Ohdaira: Innovator in Semiconductor Technology
Introduction
Takeyuki Ohdaira is a notable inventor based in Fujisawa, Japan. He has made significant contributions to the field of semiconductor technology, holding a total of 2 patents. His innovative methods have advanced the manufacturing processes in this critical industry.
Latest Patents
Ohdaira's latest patents include a "Method for manufacturing wiring in groove - In a semiconductor device" and a "Semiconductor device and method for manufacturing the same." In these inventions, an insulating film is deposited on a silicon substrate, followed by the formation of a concave groove in the insulating film according to a predetermined wiring pattern. Titanium and palladium are deposited in sequence to create a titanium film and a palladium film. A silver film is then formed on the palladium film through electroplating, leading to the creation of a groove-shaped silver wiring layer by polishing. The structure is subsequently annealed at approximately 700°C, resulting in the formation of an intermetallic compound through alloying the titanium and palladium films. This process culminates in a burying type wiring layer with a resistance lower than that of aluminum, composed of the silver wiring layer and the intermetallic compound.
