Shin Ohwada is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of semiconductor manufacturing through his innovative designs and inventions. With a total of 2 patents, Ohwada has demonstrated his expertise and commitment to advancing technology.

Latest Patents

Ohwada's latest patents include a wafer holder and a polishing device. The wafer holder is designed to provide a substrate holding apparatus that can adjust the holding state of a substrate according to the polishing state. This invention ensures uniformity in the polishing amount across the entire surface of the substrate while allowing for intentional control of the polishing amount. The apparatus features a holding plate with a holding surface, a cover element that creates a sealed back pressure space, and a division element that divides the back pressure space into multiple sealed divisional spaces. Additionally, a back pressure controller is included to manage the back pressures in these spaces.

The polishing device is an apparatus for polishing workpieces, such as semiconductor wafers, to a flat mirror finish. It consists of a turntable with a polishing cloth and a top ring that presses the semiconductor wafer between the turntable and itself. A presser ring is vertically movable around the top ring, and a pressing device applies a variable pressing force to the presser ring against the polishing cloth. This innovative design enhances the efficiency and effectiveness of the polishing process.
