  • POWER DEVICE
    Publication number: 20250120105
    Abstract: A power device includes a substrate, a drift layer disposed on the substrate, a terminal region and an active region disposed in the drift layer, an electrode layer disposed on the active region, a Schottky contact layer disposed between the electrode layer and the active region, a passivation layer including a first portion that is disposed on the drift layer, and a second portion that is connected to the first portion and that has an end surface distal from the drift layer. The end surface of the second portion is flush with a top surface of the electrode layer distal from the drift layer. Another two power devices are also provided.

  • Power device and method for making the same
    Patent number: 12191376
    Abstract: A power device includes a substrate, a drift layer disposed on the substrate, a terminal region and an active region disposed in the drift layer, an electrode layer disposed on the active region, a Schottky contact layer disposed between the electrode layer and the active region, a passivation layer disposed on the drift layer, and an isolation layer disposed between the passivation layer and the electrode layer so that the passivation layer and the electrode layer are at least partially separated from each other. The isolation layer, the electrode layer, and the passivation layer each respectively has a thermal expansion coefficient a, b, c, and a>b>c.
