|Abstract:||We report an In0.7Ga0.3As n-channel multiplegate field-effect transistor (MuGFET), featuring a lightly doped high-mobility channel with 70% indium and an epi-controlled retrograde-doped fin structure to suppress short-channel effects (SCEs). The retrograde well effectively reduces subsurface punch-through in the bulk MuGFET structure. The multiple-gate structure achieves good electrostatic control of the channel potential and SCEs in the In0.7Ga0.3As n-MuGFETs as compared with planar In0.7Ga0.3As MOSFETs. The In0.7Ga 0.3As n-MuGFET with 130-nm channel length demonstrates a drain-induced barrier lowering of 135 mV/V and a drive current exceeding 840 μA/ìm at VDS = 1.5 V and VGS . VT = 3 V. © 2010 IEEE.|
