Latest Patents
Among his latest patents, Kobiki has invented a method of producing field effect transistor (FET) devices. This innovative process involves etching separation grooves and via-holes from the front surface of the substrate, followed by reducing the thickness of the substrate from the rear surface. This technique exposes the plating within the via-holes and separation grooves, allowing for the deposition of a rear surface electrode and a plated heat sink. The devices are subsequently divided from the wafer through etching or severing at designated locations.
Another significant patent focuses on the manufacturing of insulated via hole structures for semiconductors. This invention comprises a semiconductor substrate with two semiconductor layers of opposite conductivity types. The via hole structure includes a penetrating hole that is defined by the side walls of the semiconductor layers and the substrate. An electrically conducting material is applied to the side walls, in conjunction with an electrically isolating region formed with ion flux before or after the etching process.
