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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Sidewall passivation for HEMT devices","description":"Some embodiments of the present disclosure relate to a high electron mobility transistor (HEMT) which includes a heterojunction structure arranged over a semiconductor substrate.
