Title: **Innovations of Tatsushi Higashi: A Leader in Semiconductor Technology**
Introduction
Tatsushi Higashi, an accomplished inventor based in Tokyo, Japan, has made significant contributions to the field of semiconductor technology. With three patents to his name, his innovations focus on enhancing the reliability and effectiveness of semiconductor devices.
Latest Patents
Higashi's latest inventions include an electric contact device that establishes improved contact with contactors of other devices. This electric contact device is designed for reliable interaction with ball and strip contactors over large contact areas. It comprises a contact lead that features a ring-shaped or helical section situated between a support pole and a movable pole. When the movable pole is adjusted, the contact lead expands, allowing a contactor to be inserted, which is then wrapped by the contact lead for improved connectivity.
Furthermore, Higashi has developed a test method for chips in a semiconductor wafer utilizing a test algorithm. This method involves determining chip layouts on the wafer, where sample chips surround untested ones. The good/defective judgment for the untested chips is executed based on statistically predicted outcomes derived from the sample test results. This innovation allows for high accuracy in identifying defective chips, particularly when defects are clustered in specific regions.
