Abstract

Silicon germanium (SiGe) heterogeneous bipolar transistors (HBTs) in radio-frequency front-end low-noise amplifiers may confront a joint attack from swift heavy ions (SHIs) and strong electromagnetic pluses (EMPs) in complex nuclear and electromagnetic radiation circumstances. Herein, the coupled radiation effects of SHIs and strong EMPs on a SiGe HBT were investigated based on TCAD simulations. The results showed that the simultaneous impact originating from the SHIs and the EMPs could render the SiGe HBT more vulnerable than the impact of either factor alone. As the SHIs and the EMPs acted on the SiGe HBT simultaneously, the thermal effects of the base region were predominant and could finally cause damage to the device. The electron-hole pairs injected by the SHIs increased the lattice temperature and aggravated the thermal burnout dominated by the EMPs. This work may facilitate research on radiation effects of SiGe HBTs in the complex nuclear and electromagnetic radiation environment.

期刊介绍： Section B of Nuclear Instruments and Methods in Physics Research covers all aspects of the interaction of energetic beams with atoms, molecules and aggregate forms of matter. This includes ion beam analysis and ion beam modification of materials as well as basic data of importance for these studies. Topics of general interest include: atomic collisions in solids, particle channelling, all aspects of collision cascades, the modification of materials by energetic beams, ion implantation, irradiation - induced changes in materials, the physics and chemistry of beam interactions and the analysis of materials by all forms of energetic radiation. Modification by ion, laser and electron beams for the study of electronic materials, metals, ceramics, insulators, polymers and other important and new materials systems are included. Related studies, such as the application of ion beam analysis to biological, archaeological and geological samples as well as applications to solve problems in planetary science are also welcome. Energetic beams of interest include atomic and molecular ions, neutrons, positrons and muons, plasmas directed at surfaces, electron and photon beams, including laser treated surfaces and studies of solids by photon radiation from rotating anodes, synchrotrons, etc. In addition, the interaction between various forms of radiation and radiation-induced deposition processes are relevant.
