Effects of rapid thermal annealing (RTA) on sub-100 nm p/sup +/-n Si junctions fabricated using 10 kV FIB Ga/sup +/ implantation at doses ranging from 10/sup 13/ to 10/sup 15/ cm/sup -2/ are reported. Annealing temperature and time were varied from 550 to 700 degrees C and 30 to 120 s. It was observed that a maximum in the active carrier concentration is achieved at the critical annealing temperature of 600 degrees C. Temperatures above and below the critical temperature were followed by a decrease in the active concentration, leading to a 'reverse' annealing effect.<
