Tan dry etch
WebFeb 7, 2024 · We report on the study of tantalum nitride (TaN) gate-stack on p-GaN-based e-mode high electron mobility transistor (HEMT) on silicon. Besides offering an excellent etch selectivity of >1:30 over p-GaN under Cl2/O2/Ar-based dry etch, which is promising for self-aligned gate etch process, TaN-gated HEMTs exhibited three orders of lower forward gate …
