Abstract:
Some embodiments of the present disclosure relate to a high electron mobility transistor (HEMT) which includes a heterojunction structure arranged over a semiconductor substrate. The heterojunction structure includes a first III/V semiconductor layer, and a second III/V semiconductor layer arranged over the first III/V semiconductor layer. Source and drain regions are arranged over the second III/V semiconductor layer and are spaced apart laterally from one another. A gate structure is arranged over the heterojunction structure and is arranged between the source and drain regions. The gate structure is made of a third III-nitride material. A first passivation layer is disposed about sidewalls of the gate structure and is made of a fourth III-nitride material.

Claim (Index 1):
A high electron mobility transistor (HEMT), comprising:\n a heterojunction structure arranged over a semiconductor substrate, the heterojunction structure comprising: a first III/V semiconductor layer, and a second III/V semiconductor layer arranged over the first III/V semiconductor layer and made of a second III-nitride material; source and drain regions arranged over an upper surface of the second III/V semiconductor layer and spaced apart laterally from one another; a gate structure arranged over the heterojunction structure and arranged between the source and drain regions, wherein the gate structure is arranged over the upper surface of the second III/V semiconductor layer; a first passivation layer disposed about sidewalls of the gate structure and extending over an upper surface of the gate structure, wherein the first passivation layer is made of a III-V material; and a second passivation layer overlying the first passivation layer, wherein a material composition of the second passivation layer is different from a material composition of the first passivation layer.
