Abstract :
The effects of low dose 710 MeV Bi and 305 MeV Kr ion irradiation on boron redistribution and electric activation processes in silicon during furnace annealing have been studied. It was found that hundred MeV ion irradiation enhances the shift of boron depth distribution towards the depth of the material and significantly decreases the electrical activation of dopants. The difference in dynamics of boron activation between reference and high energy heavy ion irradiated silicon samples is attributed to formation of stable defect clusters in the ion track range
