Patent ID: 8390091

Claim:
A monolithic semiconductor structure, including; a stack of layers including: a substrate; a first layer made from a first semiconductor material; and a second layer made from a second semiconductor material, said first layer being situated between the substrate and the second layer and at least one of said first semiconductor material and said second semiconductor material containing a III-nitride material; said structure including a power transistor, including: a body formed in said stack of layers; a first power terminal at a side of said first layer facing said second layer; a second power terminal at least partly formed in said substrate; and a gate structure for controlling the propagation through said body of electric signals between said first power terminal and said second power terminal; and said structure further including a Schottky diode, including: an anode; a cathode including said substrate; and a Schottky barrier between said cathode and said anode, said Schottky barrier being situated between said substrate and an anode layer in the stack of layers.
