N-type metal-oxide-semiconductor high electron mobility transistor (MOS-HEMT) devices with an InAs-channel using atomic-layer-deposited (ALD) Al2O3 as a gate dielectric have been fabricated and characterized. The device performances of a set of scaled transistors with and without high- k gate dielectric Al2O3 have been compared to determine the optimum device structure for low power and high speed applications. The measurement results revealed that the high performance InAs-channel MOS-HEMTs with the ALD Al2O3 gate dielectric can be achieved if the structure is designed properly.
