Abstract:The impact of shallow trench isolation (STI) mechanical stress on the hysteresis effect in the output characteristics is measured in partially depleted (PD) silicon-on-insulator (SOI) metal-oxide-semiconductor field effect transistors (MOSFETs). We develop ID hysteresis, which is defined as the difference between ID versus VD forward sweep and reverse sweep. The fabricated devices show positive and negative peaks in ID hysteresis. The experimental results show that ID hysteresis declined as the STI mechanical stress increases. We also elaborate on the impact of STI mechanical stress on the ID hysteresis of PD SOI n-type MOSFETs.
