Abstract :
The radiation response of several GaAs technologies to ionizing radiation has been investigated. Self-aligned gate (SAG) E/D GaAs Metal Semiconductor FET (MESFET), SAG AlGaAs/GaAs Modulation Doped FET (MODFET), and complementary-AlGaAs/GaAs Heterostructure Insulated Gate FET (C-HIGFET) devices and circuits all demonstrated minimal sensitivity to total dose effects to 250 Mrad(GaAs). The heterostructure based technologies showed superior tolerance to high dose rate exposures, with upset levels exceeding 1Ã1010 rads(GaAs)/s.
