Introduction

Masafumi Minami, an accomplished inventor based in Tokyo, Japan, has made significant contributions to the field of semiconductor technology. With a remarkable portfolio of 12 patents, his work continues to influence the industry and shape the future of electronic devices.

Latest Patents

Among Masafumi Minami's latest innovations are two notable patents that showcase his expertise. The first is a Method for Manufacturing Semiconductor Device, which involves a sophisticated process where a lower resist is applied on a semiconductor substrate, followed by an upper resist. After forming a first opening through exposure and development, the lower resist is dissolved to create a second opening wider than the first. This process results in a resist pattern shaped like an eave with an undercut. Subsequent thermal baking causes the upper resist to shrink and bend the eave portion upward. A metal film is then deposited on the resist pattern and the exposed semiconductor substrate, forming an electrode after the removal of the resist pattern and metal film.

His second patent pertains to a Laser Diode and Method of Manufacturing Laser Diode. This invention features a laser diode that includes a ridge portion and adjacent channel portions, with unique terrace portions and supporting structures made of resin. The design incorporates a ceiling portion of resin with hollow spaces, capped with a metal layer connected to the ridge's upper surface.
