Latest Patents

One of his latest patents is a semiconductor device with a parasitic bipolar transistor. This invention enhances resistance to surges in a semiconductor device that has a semiconductor die mounted on a lead frame. The design includes an N-type embedded layer, an epitaxial layer, and a P-type semiconductor layer on the front surface of a P-type semiconductor substrate forming an IC die. A metal thin film is placed on the back surface of the semiconductor substrate, with a conductive paste containing silver particles situated between the metal thin film and a metal island. When a surge is applied to a pad electrode on the front surface of the semiconductor layer, the surge current flows from the semiconductor layer into the substrate and runs toward the metal island through the metal thin film.

Another significant patent is related to a semiconductor device and its manufacturing method. This invention addresses the challenge of reducing connection resistance values between wiring layers, which is often hindered by an oxide film formed between them. In this innovative semiconductor device, a first metal layer is embedded in opening regions that connect a first wiring layer to a second wiring layer. An opening is formed in a spin-coated resin film on the first metal layer, allowing a Cr layer to form a plating metal layer that connects to a Cu plated layer. This structure results in wider spaces among crystal grains in the Cr layer, leading to a reduction in connection resistance values.
