Abstract
Embodiments of the present disclosure describe apparatuses, methods, and systems of an integrated circuit (IC) device. The IC device may include a buffer layer disposed on a substrate, the buffer layer including gallium (Ga) and nitrogen (N) and a barrier layer disposed on the buffer layer, the barrier layer including aluminum (Al) and nitrogen (N). The IC device may further include a gate terminal and a gate dielectric layer disposed between the gate terminal and the barrier layer and/or between the gate terminal and the buffer layer. In various embodiments, the gate dielectric layer may include a fluoride- or chloride-based compound, such as calcium fluoride (CaF).
