  • Patent number: 9443784
    Abstract: A power semiconductor chip and a low-power portion that has power consumption lower than that of the power semiconductor chip are located on a predetermined surface side of a heat sink having conductivity. A first plate-shaped insulating member extends between the power semiconductor chip and the heat sink. A second plate-shaped insulating member extends between the low-power portion and the heat sink. A portion, which faces the low-power portion, of the second plate-shaped insulating member is thicker than a portion, which faces the power semiconductor chip, of the first plate-shaped insulating member.

  • Patent number: 9257542
    Abstract: A power semiconductor device includes a resistance control structure disposed in a central portion of a semiconductor substrate having a resistance to a current higher than in a peripheral portion of the substrate surrounding the central portion. The semiconductor includes a first semiconductor layer of a first conductivity type which extends laterally to run across the central portion and the peripheral portion, and a second semiconductor layer of a second conductivity type which faces the first semiconductor layer in a thickness direction and extends laterally to run across the central portion and the peripheral portion. A lifetime control layer is provided in the first semiconductor layer, extends laterally to run across the central portion and the peripheral portion and has a higher lifetime killer concentration in the central portion than the peripheral portion. The resistance control structure includes the lifetime control layer.
