PROJECT TITLE :

GaN-Based Metal-Insulator-Semiconductor High-Electron-Mobility Transistors Using Low-Pressure Chemical Vapor Deposition SiNx as Gate Dielectric

ABSTRACT:

During this letter, silicon nitride (SiNx) film deposited at 780 °C by low-pressure chemical vapor deposition (LPCVD) was utilized as gate dielectric for GaN-based metal-insulator-semiconductor high-electron-mobility transistors. The LPCVD-SiNx exhibit improved gate dielectric performance than the plasma enhanced chemical vapor deposition-SiNx, including smaller forward and reverse gate leakage, and higher forward gate breakdown voltage.
