Abstract

The influence of 0–1000 mJ/cm2 1–2 keV x-ray radiation on the MOSFET characteristics of submicron CMOS devices is investigated. Fully-integrated LOCOS- and STI-defined MOSFET structures, with abrupt- and LDD-junction geometries, are used to evaluate irradiation effects on different device design features for future (post-256 Mb DRAM) logic and DRAM technology considerations. The effects of x-ray irradiation on DRAM trench storage-node leakage are also investigated and compared to high energy ion implant-related leakage behavior.
