We compare chemical vapor deposition (CVD) and physical vapor deposition (PVD) WSi2WSi2 metal gate process for In0.53Ga0.47AsIn0.53Ga0.47As n-metal-oxide-semiconductor field-effect transistors using 10 and 6.5 nm Al2O3Al2O3 as dielectric layer. The CVD-processed metal gate device with 6.5 nm Al2O3Al...
