This work investigates AlGaN/GaN heterostructure field-effect transistors (HFETs) processed by using a simple post-metallization etching (PME) treatment. Decreased gate length ( L G) can be achieved by using nitric acid (HNO 3) PME treatment owing to the high etching selectivity of HNO 3 of Ni against the Au and GaN layer.
