2 TASK DESCRIPTION Task SiGe and Advanced Mixed Signal - Radiation GOALS/OBJECTIVES Task SiGe and Advanced Mixed Signal - Radiation  FY07 activities involve test and modeling to characterize IBM 5HP 8HP and 9HP SiGe structures and devices, and other commercial processes (IHP)  Modeling activities include 3-D device physics charge collection and TCAD simulations of circuit response in 5HP, 7HP, and 8HP SiGe HBT technologies  We will generate and evaluate simulation based solutions to RHBD architectures and related test structures  We will assess the temperature dependence of HBT concerns under cryo conditions  Test activities will also characterize the companion CMOS circuits for these BiCMOS processes, as well as strained CMOS structures  SiGe microelectronics are a commercially available high-speed, mixed signal technology applicable to a diverse range of digital, RF, and mixed signal wideband systems. In FY04-06, we proved this technology is extremely well suited for space with respect to ionizing radiation and particle damage issues, but problems arise due to the extreme sensitivity to soft errors. Our research targets these issues using collaborative test chips (including DoD-funded hardening methods) to acquire radiation effects data and support device physics and circuit level modeling.
