Title: Tatsuya Hirano: Innovator in Semiconductor Technology
Introduction
Tatsuya Hirano is a prominent inventor based in Niigata, Japan. He has made significant contributions to the field of semiconductor technology, holding a total of 2 patents. His work focuses on innovative methods for semiconductor packaging and devices.
Latest Patents
Hirano's latest patents include a semiconductor package and production method, as well as a semiconductor device. The semiconductor package production method involves die-cutting part of a lead side portion of a seal formed by molding and dam bars using a pedestal and punch. The design of the pedestal is crucial, as it features an outer surface that retreats from the side surface of the upper seal portion and an inner surface that is generally near the side surface of the lower seal portion. Additionally, the width of the upper surface of the pedestal is smaller than the overhang size of the upper seal portion. The tip end region of the lead side portion, located right under the overhang portion, has a slanted surface that slopes inwardly from top to bottom.
The semiconductor device itself includes a semiconductor chip, leads for signal transmission, fine metal wires, an encapsulant for sealing the leads, and a lid member. A metal oxide film is formed on the surface of each lead through an oxidation treatment, with a thickness greater than a natural oxide film but no more than 80 nm.
