Abstract :
Novel optimization techniques for sub-half micron gate MODFET structures are thoroughly investigated based on accurate 2-D hydrodynamic hot-electron modeling. Some novel device design concepts to be implemented in submicron-MODFET knowledge-based systems are emphasized. Device design constraints and guidelines for achieving optimum millimeter-wave performance are considered. These cover gate-length miniaturization, optimal gate-recess dimensions, and optimized single-quantum-well MODFET geometries.<>
