Title: Innovations by Yasushi Koubuchi: A Leader in Semiconductor Technology

Introduction

Yasushi Koubuchi, a prolific inventor based in Kokubunji, Japan, holds an impressive portfolio of 19 patents. His work primarily focuses on advancements in semiconductor integrated circuit devices, showcasing his expertise in this critical area of technology.

Latest Patents

Among his latest patents, Koubuchi has developed a semiconductor integrated circuit device characterized by the strategic formation of interconnections over an interlayer insulating film. This film covers MISFET devices formed on the principal surface of a semiconductor substrate. Notably, dummy interconnections are placed in regions that are spaced from the primary interconnections and also in scribing areas. Importantly, these dummy interconnections are meticulously crafted so that they do not interfere with the peripheries of bonding pads and markers. The design also includes a gate electrode of a MISFET alongside a dummy gate interconnection made from the same layer. Furthermore, Koubuchi's innovations incorporate dummy regions situated in a shallow trench element-isolation region. This approach is advanced by the utilization of Chemical Mechanical Polishing (CMP) to planarize the insulating film after the dummy members are positioned.
