Latest Patents
One of Itagaki's latest patents is for a double-sided circuit non-oxide-based ceramic substrate and the method for manufacturing it. The objective of this invention is to provide a ceramic substrate that excels in radiation properties while being cost-effective. This innovative substrate features a high heat-conductive non-oxide-based ceramic material, which includes a through hole and a holding layer formed on the wall surface of the hole. An electro-conductive metal section is held inside the through hole by the holding layer, ensuring that it does not include any active metal. Additionally, the substrate is designed with thin film electrodes that shield the exposed surfaces of the holding layer and the electro-conductive metal section.
Another significant patent by Itagaki involves a single crystal silicon carbide substrate, along with its manufacturing method and a semiconductor laser. This substrate consists of a single crystal silicon carbide material, with first and second wiring films placed on one side. An insulating portion is strategically positioned in the interstice between the two wiring films, which is created by removing a surface contaminated layer through dry etching.
