Title: **Inventor Kei Yoshikawa: Pioneering Innovations in Semiconductor Technology**
Introduction
Kei Yoshikawa, a prominent inventor based in Kanagawa-ken, Japan, has made significant contributions to the field of semiconductor technology. With a total of seven patents to his name, he continues to push the boundaries of innovation in his domain.
Latest Patents
Among his latest patents is a method for semiconductor device fabrication employing multiple mask patterns. This intricate process involves forming a resist pattern over a hard mask material film situated above a work film. It details the transformation of the material film through selective processing using the resist pattern as a mask. The evolution of the hard mask pattern is carefully orchestrated to produce a resist pattern over a non-selected region, which features an opening for exposing a selection region within the mask pattern. A unique selection etching technique is applied, allowing the etching of the work film based on the modified mask pattern. This culminates in the formation of a work film pattern that includes both a wide pattern section compliant with the exposure resolution and a slimmed pattern, which remains within the resolution limitation.
