Abstract
Back-gated InGaAs-on-insulator lateral N+NN+ MOSFETs are successfully fabricated by direct wafer bonding and selective epitaxial regrowth. These devices were characterized using a revisited pseudo-MOSFET configuration. Two different transport mechanisms are evidenced: volume conduction in the undepleted region of the film and surface conduction at the interface between InGaAs and buried insulator. We propose extraction techniques for the volume mobility and interface mobility. The impact of film thickness, channel width, and length is evaluated. Additional measurements reveal the variation of the transistor parameters at low temperature and under externally applied uniaxial tensile strain.
