摘要: | GaSb is an attractive candidate for future high-performance III–V p-channel metal-oxide-semiconductor-field-effect-transistors (pMOSFETs) because of its high hole mobility. The effect of HCl based-chemical cleaning on removing the non-self limiting and instable native oxide layer of GaSb to obtain a clean and smooth surface has been studied. It is observed that the rms roughness of a GaSb surface is significantly reduced from 2.731nm to 0.693nm by using HCl:H2O (1:3) solution. The Ni/Pt/Au ohmic contact exhibits an optimal specific contact resistivity of about 6.89×10?7Ω·cm2with a 60s rapid thermal anneal (RTA) at 250°C. Based on the chemical cleaning and ohmic contact experimental results, inversion-channel enhancement GaSb pMOSFETs are demon- cleaning and ohmic contact experimental results, inversion-channel enhancement GaSb pMOSFETs are demon-on-off (ION/IOFF) ratio of >103, and a subthreshold swing of ~250mV/decade are achieved. Combined with on-off (ION/IOFF) ratio of >103, and a subthreshold swing of ~250mV/decade are achieved. Combined with22 pMOSFET. |
