Title: Masanori Iwahashi: Innovator in Semiconductor Technology
Introduction
Masanori Iwahashi is a prominent inventor based in Utsunomiya, Japan. He has made significant contributions to the field of semiconductor technology, holding a total of 2 patents. His work focuses on enhancing the performance and reliability of semiconductor devices.
Latest Patents
Iwahashi's latest patents include innovative designs aimed at preventing light interference in semiconductor devices. The first patent describes a semiconductor device that prevents light from entering its substrate transistor. This is achieved by forming an uppermost metal wiring layer made of titanium (Ti) and titanium nitride (TiN), on which tungsten (W) is deposited to fill a via hole. This design effectively prevents light from reaching the substrate transistor, thereby avoiding potential malfunctions.
The second patent involves a multiple metallization structure for a reflection-type liquid crystal. In this design, a thin interconnection layer made of TiN/Ti is formed on a flat uppermost interlayer insulating film. This layer is then covered with a protection film made of p-SiN, ensuring that the uppermost interconnection layer is exposed to the surface of the chip. This innovative approach enhances the performance of Si chip-based liquid crystals.
