Direct correlation and simple overstress methods to estimate IC response in strategic and space environments from laboratory transistor and IC data are investigated. Transistors and ICs were irradiated at dose rates from 0.2 rad(SiO{sub 2})/s to 106 rad(SiO{sub 2})/s. Laboratory transistor and IC data are compared to IC data taken at high and low dose rates. Over a wide range of process conditions and hardness levels, laboratory measurements of {delta}Vot correlate well with IC leakage current at high dose rates for ICs with gate-oxide dominated response. For ICs whose response is dominated by parasitic field oxide structures, laboratory measurements of both transistor and IC leakage currents correlate well with IC hardness at high dose rates. For dose levels up to {approx equal}500 krad(SiO{sub 2}), it is shown that a simple factor-of-3 overtest can be used as a conservative estimate of radiation hardness of these technologies for strategic applications, provided that both functional and parametric testing is performed following x-ray irradiations at a dose rate of {approx equal} 2000 rad(SiO{sub 2})/s. For space environments, a laboratory irradiation to 1.5-times the required system level followed by a one week 100{degrees}C biased anneal gave conservative estimates of IC hardness.
