Abstract: Monolithic FETs including a majority carrier channel in a first high carrier mobility semiconductor material disposed over a substrate. While a mask, such as a gate stack or sacrificial gate stack, is covering a lateral channel region, a spacer of a high carrier mobility semiconductor material is overgrown, for example wrapping around a dielectric lateral spacer, to increase effective spacing between the transistor source and drain without a concomitant increase in transistor footprint. Source/drain regions couple electrically to the lateral channel region through the high-mobility semiconductor spacer, which may be substantially undoped (i.e. intrinsic). With effective channel length for a given lateral gate dimension increased, the transistor footprint for a given off-state leakage may be reduced or off-state source/drain leakage for a given transistor footprint may be reduced, for example.
