中文摘要	Changes in the typical electronic parameters of SiGe HBTs irradiated by pulse neutron and gamma rays from a reactor are measured. The DC common emitter static current gain of the SiGe HBTs only decreases by about 20% after being irradiated with 1 * 10/sup 13 / cm/sup -2/ neutron fluence and 256.85 Gy(Si) gamma total dose. The base current and the junction leakage current increase, while the collector current and the breakdown voltage decrease for SiGe HBTs after radiation. After irradiation, the cutoff frequency f/sub T/ is nearly unchanged, but the maximum oscillation frequency f/sub max / decreases a little. The mechanisms of the reactor pulse neutron and gamma rays irradiation damage for SiGe HBTs are preliminarily analyzed.
