Abstract :
Space applications using advanced foundry processes require device models that accurately include the dependence of total-ionizing dose (TID) response on process variability and layout. An automated flow is described for TID-aware process design kit generation using new test chips, modeling, and simulation. The variability of TID-induced leakage current and transistor mismatch both increase after irradiation.
