Latest Patents

Hasegawa holds a patent for a semiconductor device, which includes a method of manufacturing that involves forming an inter-layer insulating film on a semiconductor substrate. The process begins with the formation of a first metal film on the inter-layer insulating film. A first resist is then applied to the first metal film and patterned. Anisotropic etching is performed on the first metal film using the first resist as a mask. After removing the first resist, a second metal film is formed on the inter-layer insulating film to cover the remaining first metal film. A second resist is then formed on the second metal film in areas where the first metal film exists and partially where it does not. Anisotropic etching is performed on the second metal film using the second resist as a mask, resulting in a bonding pad that incorporates both the first and second metal films, along with upper layer wiring. Finally, a surface protection film is formed over the bonding pad, and a pad opening is created.
