Abstract :
Dose-rate effects are studied in shallow trench isolation regions. Increased damage is observed at low dose rate, with a different dose dependence compared to tests done at high dose rate. A three-dimensional modeling program was used to show that charge trapping occurs much deeper in the trench region when sufficient charge is present to reduce the field in the trench.
