Defect and Material Characterization
The photoconductivity spectrum in extrinsic regiono was measured in irradiated Si samples at 18
K temperature. The samples were treated by isochronal annealing in a range 80-250 C.
The deep levels were resolved by use of Lucovsky model.
A series of levels was observed and a number of deep centers and their contribution on the photoconductivity were dependent on annealing.
The comparison...

Defect and Material Characterization
Isochronal annealing studies have been performed on neutron-irradiated Epi-Do and MCz diodes. The MCz diode, irradiated with 3E11 n/cm², was investigated with DLTS. The annealing results of cluster related defects will be presented and compared to reverse current data. After injection of 1 Ampere forward current, a bistable effect of the cluster related defects E4 and E5 was observed. Further...

A comparative analysis of the recombination, generation and reverse recovery lifetime dependent on stopped protons fluence and isochronal anneal temperature is presented for FZ Si structures. In DLTS, heat treatments indicate transformations of majority and minority carrier traps. These changes are also revealed by variations of the excess carrier decay lifetime. The main transformations can...
