Title: Yasuaki Tsuzuki: Innovator in Thin Film Technology

Introduction

Yasuaki Tsuzuki is a notable inventor based in Anjo, Japan. He has made significant contributions to the field of thin film technology, holding a total of 6 patents. His work primarily focuses on methods of etching metallic thin films, which are crucial in various electronic applications.

Latest Patents

One of Tsuzuki's latest patents involves a method of etching metallic thin film on a thin film resistor. In this process, an aluminum (Al) film is formed on a barrier metal that covers a thin film resistor, creating a first opening. A photo-resist is then applied to the Al film and patterned to create a second opening, which has a smaller area than the first opening. This second opening exposes the barrier metal, allowing it to be etched through the second opening. Notably, the etching occurs from an inner portion more than the opening end of the first opening, effectively preventing under-cutting of the barrier metal.
