Rapid thermal process (RTP) sintering of aluminum metallization has been used in p+-n junction detector fabrication. For the same thickness of aluminum film and at the same RTP sintering condition, the leakage current of the p+-n junction detectors with sputtered Al metallization showed at least a 50% improvement after sintering, and no spiking phenomena were observed compared to the detectors with evaporated Al contacts. RTP sintering in 4% H2/N2 ambient passivates the defects introduced by sputtering and the damage caused by the 60Co irradiation
