Total Dose and Transient Response of SiGe HBTs from a New 4th-Generation, 90 nm SiGe BiCMOS Technology

The total ionizing dose and laser-induced transient response of a new 4th generation 90 nm IBM SiGe 9HP technology are investigated. Total dose testing was performed with 63.3 MeV protons at the Crocker Nuclear Laboratory at the University of California, Davis. Transient testing was performed on the two-photon absorption system at Naval Research Laboratory. Results show that the SiGe HBTs are dose-tolerant up to 3 Mrad(SiO2) and exhibit reduced single event transients compared to earlier SiGe generations.
