With a total of 3 patents to his name, Kamiyama's work has advanced the manufacturing processes in this critical area of electronics.

Latest Patents

Kamiyama's latest patents focus on a method of manufacturing a SOI structure that incorporates a silicon germanium (SiGe) layer between silicon and the insulator. This innovative approach involves the epitaxial growth of a first SiGe layer, a silicon layer, and a second SiGe layer over a first substrate. Following this, an insulating layer is formed on the second SiGe layer. The process includes implanting impurity ions into a specific location of the first substrate to create an impurity implantation region. A second substrate is then bonded to the insulating layer on the first substrate. After separating the first substrate along the impurity implantation region, the remaining first SiGe layer is removed to expose the surface of the silicon layer.
