Abstract:
A compound semiconductor device includes an electron transit layer, a spacer layer disposed on the electron transit layer, and an electron supply layer disposed on the spacer layer and containing a donor impurity. The electron supply layer has a concentration distribution of the donor impurity where the donor impurity is at a first concentration at an interface between the electron supply layer and the spacer layer and at a second concentration lower than the first concentration at an upper surface of the electron supply layer, and a concentration of the donor impurity at one of arbitrarily-selected two positions closer to the upper surface in a thickness direction of the electron supply layer is less than the concentration of the donor impurity at another one of the two positions closer to the interface in the thickness direction.

Claim (Index 3):
The compound semiconductor device as claimed in  claim 2 , wherein the concentration of the donor impurity in the first layer decreases as a distance from the interface increases.
