Abstract :
A study was initiated to investigate the effects of gamma (total ionizing dose), prompt gamma (gamma-dot), and neutron radiation on commercially available power integrated circuits. A dielectric-isolated bipolar-CMOS-DMOS (BCDMOS) technology was selected for this characterization. Total-ionizing-dose testing resulted in device failure at 30 krad(Si). Gamma-dot testing (30-ns pulsewidth) resulted in device failure due to transient upset of the CMOS logic at 109 rads(Si)/s. Neutron testing resulted in severe degradation in performance, but devices remained functional after receiving a fluence of 2×1014 n/cm2. An attempt was made to harden the BCDMOS technology to gamma radiation
