Title: Satoshi Yanaura: Innovator in Semiconductor Technology
Introduction
Satoshi Yanaura is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of semiconductor technology, holding a total of 6 patents. His innovative work focuses on methods for producing multi-layered wiring boards and advancements in semiconductor device sealing.
Latest Patents
One of Yanaura's latest patents is a method of producing a multi-layered wiring board. This method involves subjecting photosensitive resin to exposure and development treatment to form holes of predetermined size and shape. The process continues with the deposition and formation of curable resin to the insulating layer, followed by heat treatment to create a cured thin film on the surface. The final step involves removing the curable resin to leave the cured thin film, resulting in via-holes with reduced opening sizes.
Another notable patent is related to a semiconductor device that utilizes a silicone resin for sealing semiconductor chips. This cured silicone resin, obtained by curing at a specific temperature, exhibits a percent elongation after fracture of not less than 4% of a penetration number at room temperature. The semiconductor device sealed with this resin demonstrates resistance to cracking, void formation, and interfacial peeling-off during heat cycles or vibration tests.
