Title: Masaru Iwasaki: Innovator in Photodetector Technology

Introduction

Masaru Iwasaki is a notable inventor based in Izumisano, Japan. He has made significant contributions to the field of photodetector technology, holding a total of 6 patents. His work has advanced the capabilities of light-receiving devices, showcasing his expertise and innovative spirit.

Latest Patents

One of Iwasaki's latest patents is a photodetector with a multilayer filter. This invention discloses a photodetector that features a light-receiving substrate mounted on a recessed portion of a ceramic stem. An electrode pad is formed on a P-type layer of the light-receiving substrate, while another electrode pad is formed on an N-type layer. The optical multilayer filter is constructed on the light-receiving substrate, excluding the regions of the electrode pads. Additionally, an epoxy transparent resin is poured into the recessed portion of the stem and cured, forming a protective resin covering for the light-receiving substrate. The optical multilayer filter consists of amorphous low refractive index films made of SiC.sub.2 and high refractive index films made of TiO.sub.2, which are alternately stacked.

Another significant patent involves a method for manufacturing a contact type one-dimensional image sensor. This method includes providing a light-receiving element portion composed of Group II-VI compound semiconductors containing Cd on a substrate. It also involves creating a matrix wiring portion on the same substrate as the light-receiving element. The method is characterized by forming an insulating layer that covers the light-receiving element portion, ensuring the integrity of the sensor's design.
