Introduction

Hiromi Fujisawa is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of wire bonding technology, holding a total of 6 patents. His innovative approaches have enhanced the efficiency and effectiveness of wire bonding processes in semiconductor devices.

Latest Patents

Fujisawa's latest patents include a wire bonding method, wire bonding apparatus, and wire bonding control program. The wire bonding method he developed enables the formation of a low loop with a height not exceeding two times the wire diameter while ensuring sufficient pull strength. This method involves forming a contact-bonded ball at a first bonding point, after which a capillary moves upward and toward a second bonding point to press the side surface of the upper portion of the contact-bonded ball. This process creates a protruded portion on the top of the ball, facilitating the formation of a wire drawing portion that allows for horizontal wire drawing. Additionally, his wire loop invention includes a wire connecting two bonding points, where an additional wire loop is formed without cutting the wire, enhancing the bonding process.
