Abstract
A semiconductor device has a substrate made of a first semiconductor material. The first semiconductor material is silicon carbide. A first semiconductor layer made of the first semiconductor material is disposed over the substrate. A second semiconductor layer made of a second semiconductor material dissimilar from the first semiconductor material is disposed over the first semiconductor layer. The second semiconductor material is silicon. A third semiconductor layer made of the second semiconductor material can be disposed between the first semiconductor layer and second semiconductor layer. A semiconductor device is formed in the second semiconductor layer. The semiconductor device can be a power MOSFET or diode. The second semiconductor layer with the electrical component provides a first portion of a breakdown voltage for the semiconductor device and the first semiconductor layer and substrate provide a second portion of the breakdown voltage for the semiconductor device.
