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.
