Abstract:
A semiconductor device includes a first gallium nitride layer disposed on a semiconductor substrate, and an aluminum gallium nitride layer disposed on the first gallium nitride layer. The semiconductor device also includes an upper recess and a lower recess disposed in the aluminum gallium nitride layer, wherein the upper recess adjoins the lower recess, and the upper recess has a width that is greater than that of the lower recess. The semiconductor device further includes a second gallium nitride layer disposed in the first recess and the second recess, and a gate structure disposed on the second gallium nitride layer. In addition, the semiconductor device includes a source electrode and a drain electrode disposed on the aluminum gallium nitride layer.

Claim (Index 12):
The semiconductor device as claimed in  claim 10 , wherein the aluminum gallium nitride layer has a first thickness under the first recess, a second thickness under the second recess, and a third thickness under the source electrode, and\n wherein the third thickness is greater than the first thickness, and the first thickness is greater than the second thickness.
