Title: Ichiro Fujii: Innovator in Photocell Technology

Introduction

Ichiro Fujii is a notable inventor based in Dallas, TX (US), recognized for his contributions to the field of photocell technology. With a focus on developing advanced light detection systems, Fujii has made significant strides in the innovation of metal-insulator-semiconductor (M-I-S) structures.

Latest Patents

Fujii holds a patent for a "Metal-insulator-semiconductor photocell and imager." This invention features a photocell designed to detect light through a unique configuration of at least two tiers or structures. Each tier incorporates either an M-I-S or a semiconductor-insulator-metal (S-I-M) structure. The M-I-S structure includes a semiconductor diffusion layer that can develop a depletion region, a thin insulator layer, and a contact layer. The S-I-M structure, on the other hand, consists of a contact layer, a thin insulator layer, and a semiconductor diffusion layer capable of developing a depletion region. When light strikes these depletion regions, a current flows through the respective contact layer, indicating the light detected. Additionally, the invention includes two- and three-tiered photocells that can detect various components of incident light, making them suitable for use in photo-imagers.
