Latest Patents

Omoto's latest patents include a semiconductor device and a method for manufacturing the semiconductor device. This innovative semiconductor device comprises an insulating substrate, a semiconductor chip, a plate member, and a cooler. The insulating substrate features insulating ceramics that serve as an insulating plate, with conductive plates positioned on opposite surfaces of the insulating ceramics. The semiconductor chip is mounted on the upper surface of the insulating substrate, while the plate member is bonded to the lower surface. The cooler is attached to the lower surface of the plate member. Notably, at least one of the bonding processes between the insulating substrate and the plate member, as well as between the plate member and the cooler, utilizes a bonding member primarily composed of tin. Additionally, the cyclic stress of the plate member is designed to be less than the tensile strength of the bonding member.

Another significant patent by Omoto is for an insulated circuit board, which includes an insulated substrate, a first electrode, and a second electrode. This design features a thin portion in a corner area, which occupies a portion of the length of the outer edges from a vertex of at least one of the electrodes. The thin portion has a thickness that is smaller than that of the surrounding regions. The planar shape of the thin portion is surrounded by first and second sides that are orthogonal to each other, along with a curved portion that extends away from the vertex.
