  • Publication number: 20210233949
    Abstract: Deformation of a semiconductor chip is to be prevented in a semiconductor device in which a heat releasing plate and a circuit board are disposed. The semiconductor device includes the semiconductor chip, the circuit board, the heat releasing plate, an adhesive member, and a conductive member. The circuit board transmits a signal of the semiconductor chip. The heat releasing plate has the semiconductor chip disposed thereon, and has an opening in a region on the outer side of a semiconductor chip placement region that is a region in which the semiconductor chip is disposed. The adhesive member is disposed in a region on the outer side of the opening on a different surface of the heat releasing plate from the surface on which the semiconductor chip is disposed, and bonds the circuit board and the heat releasing plate to each other. The conductive member connects the semiconductor chip and the circuit board to each other via the opening.

  • Patent number: 8092269
    Abstract: A decrease in yield and degradation of productivity can be avoided when a spark plug having an insulator with low mechanical strength is manufactured. In a second process, a terminal electrode 15 is inserted to a predetermined position in a state where an insulator 12 is heated to a temperature equal to or greater than the softening temperatures of first to third powder materials 16P, 17P, and 18P such that the first powder material 16P becomes a first conductive sealing material layer 16, the second powder material 17P becomes a resistor 17, and the third powder material 18P becomes a second conductive sealing material layer 18. In addition, a speed at which the terminal electrode 15 is inserted is reduced between the start and the end of the second process.
