Latest Patents
One of his latest patents is for a flexible tab semiconductor device. This invention features a TAB semiconductor device where one end of each lead, fixed by a TAB tape, connects to a corresponding electrode on a semiconductor pellet. The TAB tape includes thin leads fixed on a film, with a window portion that allows users to cut the leads as needed for mounting. The leads consist of normal signal leads and wider leads, which have slits to ensure uniform widths throughout the window portion.
Another notable patent is a method for making a semiconductor device with lead pins and a metal base. This method improves the Pin Grid Array (PGA) by allowing multiple lead pins to project from the undersurface of a metal base as input and output terminals for Large Scale Integrated-circuits (LSI). The process involves mounting a semiconductor chip on a heat sink, superposing a printed circuit board, and connecting electrical lead pins to wiring patterns. Additionally, a central portion patterning wiring layer is included for gold plating, which stabilizes the connection with bonding wires.
