    This work characterizes the effects of gate-length (LG) scaling in a self-aligned gate (SAG) β-Ga2O3 MOSFET process. Additional performance gains are expected by extending the SAG process from large LG to sub-micrometer dimensions.  This data incorporates LG scaling down to 200 nm to improve device performance in Ga2O3 SAG MOSFETs using a stepper lithography process to define sub-micron gate lengths.
