Abstract

We report results of very sensitive electron spin (ESR) and electrical measurements made on MOSFETs subjected to medium energy proton bombardment. We observe that the measured defect density levels are similar for both the ESR measurements and electrical measurements. The density of defects is observed to be larger for proton bombarded devices compared to devices irradiated with much larger doses of 60Co gammna rays. Initial ESR and electrical measurements were made on-site soon after bombardment in the cyclotron.
