Abstract:
A method of forming a semiconductor device includes providing a heterojunction semiconductor body. The heterojunction semiconductor body includes a type III-V semiconductor back-barrier region, a type III-V semiconductor channel layer formed on the back-barrier region, and a type III-V semiconductor barrier layer formed on the back-barrier region. A first two-dimensional charge carrier gas is at an interface between the channel and barrier layers. A second two-dimensional charge carrier gas is disposed below the first two-dimensional charge carrier gas. A deep contact structure in the heterojunction semiconductor body that extends through the channel layer and forms an interface with the second two-dimensional charge carrier gas is formed. The first semiconductor region includes a first contact material that provides a conductive path for majority carriers of the second two-dimensional charge carrier gas at the interface with the second two-dimensional charge carrier gas.

Claim (Index 8):
The method of  claim 7 , further comprising forming a drain biasing structure, the drain biasing structure comprising: a third semiconductor region disposed on the upper surface of the barrier layer between the gate structure and the first input-output electrode, and an electrically conductive connection between the third semiconductor region and the first input-output electrode, wherein the third semiconductor region is formed together with the first contact material of the deep contact structure and the second semiconductor region from the first layer of the first semiconductor material that is epitaxially grown on the heterojunction semiconductor body and subsequently patterned in the common lithography step.
