Title: Innovations by Yoshinori Hosoki
Introduction
Yoshinori Hosoki is a notable inventor based in Kawasaki, Japan. He has made significant contributions to the field of semiconductor technology. With a total of 2 patents to his name, his work has had a considerable impact on the industry.
Latest Patents
One of his latest patents is a method of manufacturing a semiconductor substrate. This method involves preparing one hundred silicon bodies, each consisting of two silicon wafers held together by cohesion after polishing and heating processes. The process further includes stacking the silicon bodies to form a stacked body and cylindrically grinding the side surface of the stacked body by a predetermined amount.
Another significant patent is for a substrate structure for a composite semiconductor device. In this invention, the main surface of a first semiconductor substrate is bonded to the main surface of a second semiconductor substrate with an insulation film in between. The first semiconductor substrate and insulation film are selectively etched to form an etched portion that reaches at least the second semiconductor substrate. An impurity layer with a different concentration is formed on the exposed surface area, and an epitaxial layer is created in the etched portion. The elements are then formed in the composite substrate based on the pattern created.
