Latest Patents

One of Seki's latest patents is a manufacturing method of a semiconductor device. This invention focuses on forming a homogeneous film in a via hole created in a semiconductor device using the Bosch process. The process involves etching the semiconductor substrate from one surface to the other, followed by the removal of the mask layer and flattening the sidewall of the via hole through dry etching. The result is a uniformly formed insulation film and barrier layer within the via hole.

Another notable patent is for a mesa type semiconductor device and its manufacturing method. This invention aims to increase the withstand voltage while reducing leakage current. It involves forming an N-type semiconductor layer on a semiconductor substrate, followed by a P-type semiconductor layer. A mesa groove is then created by etching, and subsequent wet etching removes any damaged layers, ensuring the mesa groove's width increases toward the surface of the P-type layer. This innovative approach enhances the overall performance of the semiconductor device.
