  • Patent number: 11923262
    Abstract: An electrical apparatus includes a semiconductor element, conductors and a covering resin. The conductors are connected to the semiconductor element. At least one of the conductors extends in a first direction. The covering resin covers the semiconductor element and a portion of each of the conductors. The conductors respectively include covering portions and exposing portions. Each of the covering portions is covered by the covering resin. Each of the exposing portions is exposed from the covering resin. The conductors are aligned in a second direction. Two of the exposing portions closest to each other are spaced apart in each of the second direction and a third direction. The third direction is perpendicular to the first direction and the second direction. A shortest separation distance between two closest covering portions is shorter than a shortest separation distance between two closest exposing portions.

  • Publication number: 20230298957
    Abstract: An electric apparatus includes: a first stacked body in which a first semiconductor chip having a first switch is stacked on a first mounting portion; a second stacked body in which a second semiconductor chip having a second switch is stacked on a second mounting portion; a temperature sensor provided in the first stacked body to detect a temperature of the first switch; and a current sensor provided in the second stacked body to detect a current flowing through the second switch. The second stacked body has a heat dissipation property higher than that of the first stacked body.

  • Publication number: 20230016437
    Abstract: In a semiconductor device, a first wiring member is electrically connected to a first main electrode on a first surface of a semiconductor element, and a second wiring member is electrically connected to a second main electrode on a second surface of the semiconductor element. An encapsulating body encapsulates at least a part of each of the first and second wiring members, the semiconductor element and a bonding wire. The semiconductor element has a protective film on the first surface of the semiconductor substrate, and the pad has an exposed surface exposed from an opening of the protective film. The exposed surface includes a connection area to which the bonding wire is connected, and a peripheral area on a periphery of the connection area. The peripheral area has a surface that defines an angle of 90 degrees or less relative to a surface of the connection area.

  • Patent number: 8518809
    Abstract: A manufacturing method of an SiC single crystal includes preparing an SiC substrate, implanting ions into a surface portion of the SiC substrate to form an ion implantation layer, activating the ions implanted into the surface portion of the SiC substrate by annealing, chemically etching the surface portion of the SiC substrate to form an etch pit that is caused by a threading screw dislocation included in the SiC substrate and performing an epitaxial growth of SiC to form an SiC growth layer on a surface of the SiC substrate including an inner wall of the etch pit in such a manner that portions of the SiC growth layer grown on the inner wall of the etch pit join with each other.

  • Publication number: 20080053643
    Abstract: A surface polyaniline layer comprising a polyaniline and/or a derivative thereof capable of generating active oxygen or hydrogen peroxide upon the reaction with the water component in external air that comes in contact therewith, is formed on at least a portion of the outermost surface of a base body constituting tubes and/or fins, wherein a benzenoid/quinoid ratio in the surface polyaniline layer (defined as a ratio of an absorbancy of the benzenoid structure to an absorbancy of the quinoid structure in the polyaniline and/or the derivative thereof) is in a range of about 0.5 to about 3.0.
