Abstract : We have utilized electron spin resonance (ESR), including a new and much more sensitive ESR technique called spin dependent recombination (SDR), to study radiation damage in metal/oxide/silicon (MOS) field effect transistors (MOSFETS). Our study has led to a considerably greater understanding of the electronic properties of radiation induced interface state defect structure and the relationship of the atomic scale geometry of these defects to their electronic properties. We have also studied the role of atomic scale stress in the creation of E' centers in SiO2. The E' center is the dominant deep hole trap in MOS oxides. In addition, we have used ESR to study the role of hydrogen in the MOS radiation damage process. jg
