Abstract

Transformation of radiation-induced defects in p +-n-n + structures fabricated from highresistivity n-type silicon subjected to cyclic irradiation and annealing is investigated. The kinetic behavior of the increase in the concentration of the Ci-Oi defects is analyzed as a function of the detector fabrication process. During the second irradiation cycle a transformation of the defects, which were formed as a result of annealing of the original radiation defects, is observed. The appearance of “hidden” sources of deep center formation is revealed. It is established that the presence of a higher oxygen concentration, which arises in the samples as a result of the extended silicon oxidation process, results in a more active complex-formation of carbon-containing defects in comparison with samples with reduced oxygen content.
