Title: The Innovations of Shuichi Murakami

Introduction

Shuichi Murakami is a notable inventor based in Hirakata, Japan. He has made significant contributions to the field of electronics, particularly in the fabrication of electronic circuit boards and semiconductor devices. With a total of 2 patents, his work has had a considerable impact on the industry.

Latest Patents

Murakami's latest patents include a method for fabricating electronic circuit boards. This innovative process involves forming a predetermined number of resistors with various resistances based on a circuit design stored in memory on a nonconductive substrate. The substrate is then divided into discrete resistors, which are mounted on a circuit board and tested for operational characteristics. If any resistors do not meet the required specifications, their resistances can be corrected, resulting in an electronic circuit board with accurate electric constants. The complete fabrication of electronic circuit boards is achieved through the repetition of these steps.

Another significant patent is a bonding method for semiconductor devices using a film carrier. In this method, a heat-resistive insulating layer is deposited over a dummy wafer that has a photo-resist film with a predetermined pattern. The photo-resist film and insulating layer are removed to create openings, and bumps are formed on these openings through plating. After transferring the bumps to inner leads, they are bonded to the bonding pads of the semiconductor element.
