Abstract
III-V semiconductor devices such as, e.g., MESFET, JFET, MOSFET, and IGFET devices are provided with relatively high-ohmic gates or wide gate finger widths as is desirable for maximum utilization of a semiconductor surface. For example, aluminum gate electrodes having a cross-sectional area of 1.2 square micrometer and a length of 300 micrometers or more are used. The resulting devices have unexpectedly high power handling capability.
