Abstract

In_xGa_1-xAs FinFETs with varying indium percentage, x, and vertical body thicknesses, are fabricated in a closely packed fin configuration (10 fins per micron of layout area) and their relative performance analyzed and benchmarked. In_0.7Ga_0.3As quantum well FinFET (QWFF) exhibits peak field effect mobility of 3,000 cm²/V-sec at a fin width of 38nm with highest performance. Short channel In_0.7Ga_0.3As QWFF (L_g=120nm) exhibits I_DSAT of 1.16mA/μm at V_G-V_T=1V and extrinsic peak g_m=1.9mS/μm at V_DS=0.5V and I_OFF=30 nA/μm. Components of external resistance (R_Ext), side wall DIT, fin profile are analyzed to investigate feasibility of In_xGa_1-xAs FinFET for beyond 10nm technology node.
