Latest Patents

Kamiya holds a patent for a semiconductor apparatus that features a unique design. In this 3-terminal package sealed semiconductor device, such as a transistor or a thyristor, an insulator formed between the respective lead conductors is made of alumina ceramic. The electrode conductor base, which is one of the lead conductors for mounting a semiconductor device, is made of a copper-tungsten sintered alloy containing 2% to 48% by volume of copper. This design allows the thermal expansion coefficient of the insulator to closely match that of the electrode conductor base. As a result, it eliminates the need for a conventionally used intermediate damping member, leading to a compact semiconductor apparatus with high packaging density. This innovation enables the device to switch large currents at high speeds, with the lead conductors designed to achieve high-speed large-current switching.
