Claim 15:
16. A structure comprising:
a gate comprising:
a first gate section on a barrier layer above a channel layer; and
a second gate section on the first gate section;

a source-side gate sidewall spacer positioned laterally adjacent to the first gate section, wherein the second gate section extends over the source-side gate sidewall spacer;
a source terminal comprising:
a first source region extending through the barrier layer, wherein the first source region has a proximal portion adjacent to the source-side gate sidewall spacer and a distal portion; and
a second source region on the distal portion of the first source region;

a source-side dielectric liner on the proximal portion of the first source region and positioned laterally between the second gate section and the second source region;
a drain-side gate sidewall spacer positioned laterally adjacent to the first gate section opposite the source-side gate sidewall spacer, wherein the source-side gate sidewall spacer and the drain-side gate sidewall spacer are asymmetric with the drain-side gate sidewall spacer being L-shaped and wider than the source-side gate sidewall spacer; and
a drain terminal extending through the barrier layer and positioned laterally adjacent to the drain-side gate sidewall spacer.
