Title: Koji Tsushima: Innovator in Fine Pattern Transcription
Introduction
Koji Tsushima is a notable inventor based in Kodama-gun, Japan. He has made significant contributions to the field of fine pattern transcription, holding a total of 5 patents. His work focuses on developing methods and apparatuses that enhance the efficiency and quality of pattern transcription.
Latest Patents
One of Tsushima's latest patents is a method and apparatus for transcripting fine patterns. This innovative approach prevents the ingress of bubbles during the transcription process, allowing for high throughput with a relatively compact apparatus. The method involves vacuum suction on the back surface of a stamper, which is then brought into close contact with a transcription target. The stamper is designed to deform into a spherical shape or bend, expanding the contact area and preventing air bubbles from entering between the stamper and the target.
Another significant patent is the fine-structure transfer apparatus. This apparatus features a base plate with two posts and an elongated stamper fixed to one post. The stamper is supported in a vertically movable manner, allowing for precise control during the transfer process. A pressure-applying unit is integrated to facilitate the transfer of fine patterns, characterized by the ease of detaching the stamper from the transfer element.
