Latest Patents

Sachiko Shibuya holds a patent for a semiconductor device that features a memory cell portion and a logic portion. The patent describes a structure where second-layered aluminum wires are formed on first-layered aluminum wires, with an interlayer insulating film in between. This design reduces the labor required for mask data design and increases the coating ratio of resist to the aluminum layer while minimizing the reduction in ultraviolet ray transmittance. As a result, the amount of reaction compound supplied from the resist into the aluminum layer increases, preventing undercutting of the second-layered aluminum wires. This innovation effectively prevents thinning of the logic portion's subsequent-layered aluminum wires.
