Title: Inventor Naokatsu Ikegami: Pioneering Advances in Semiconductor and Sensor Technology
Introduction
Naokatsu Ikegami, an inventive mind based in Saitama, Japan, has made significant contributions to the field of technology with a notable portfolio of 14 patents. His innovations primarily focus on semiconductor fabrication and acceleration sensors, showcasing his expertise and creativity in engineering.
Latest Patents
Ikegami's latest patents include a method of fabricating semiconductor devices that involves forming a protective layer and subsequently removing it after etching a trench. This intricate process entails alternately repeating etching and deposition steps to create a trench structure via dry-etching on the semiconductor substrate's exposed surface. A protective film is deposited to suppress etching of the trench's side walls, and heat treatment is applied at temperatures ranging from 300 to 500°C to further stabilize the substrate.
Another noteworthy invention by Ikegami is an acceleration sensor that can be manufactured through a simplified method. This design incorporates a mass that is movably linked to a peripheral attachment section, featuring stoppers that control the mass's motion. The sensor utilizes a curable elastic adhesive that absorbs impact when the mass strikes the stoppers, thus enhancing durability against mechanical shocks. This innovative approach not only streamlines the manufacturing process but also reduces associated costs.
