摘要

Various ultra-shallow ~(11)B~+ and ~(49)BF_2~+ implanted Si wafers were annealed using xenon arc flash lamps. The duration of illumination was controlled between 0.1 ms and 10 ms. Characteristics of ultra-shallow ~(11)B~+ and ~(49)BF_2~+ implanted Si wafers were investigated in terms of electrical activation and dopant redistribution after annealing. Sheet resistance was measured after exposure under various flash annealing conditions. Changes in dopant depth profile and crystal defect density were investigated before and after flash anneal using secondary ion mass spectroscopy (SIMS) and cross-sectional transmission electron microscopy (XTEM).
