Latest Patents

Onishi holds a noteworthy patent titled "Method for fabricating hybrid integrated circuit." This innovative method encompasses several steps, including baking a conductor of a first group on an insulating ceramic substrate. The process further involves creating an insulating porous active layer that includes both glass and a small quantity of a metal component, which plays a crucial catalytic role in electroless plating. A resist pattern is then formed on the active layer via a photomask, enabling the formation of a conductor of a second group through electroless plating on the exposed area of the active layer. The key feature of this invention is that it allows for a conductive portion of the active layer to be sandwiched between conductors while maintaining insulation where it contacts the substrate.
