Abstract :
Results are presented from the first submicron gate length complementary heterostructure insulated gate field effect transistor (C-HIGFET) devices and circuits (n- and p-HIGFET gate lengths of 0.7 mu m). This reduction in gate length results in a factor of two increase in the switching speed of C-HIGFET gates, and a 35% reduction in switching-power/frequency without any corresponding increase in the standby power consumption. Fully functional 4Kbit SRAMs have been fabricated using this submicron C-HIGFET technology, and operation of 4Kbit SRAMs at clock frequencies of up to 360 MHz have been demonstrated.<>
