TECHNIQUE FOR REDUCING CRYSTAL DEFECTS IN STRAINED TRANSISTORS BY TILTED PREAMORPHIZATION

摘要

By performing a tilted amorphization implantation (208, 308P, 308N) and a subsequent re-crystallization on the basis of a stressed overlying material (209, 211, 309, 311, 319S), a highly efficient strain-inducing mechanism is provided. The tilted amorphization implantation (208, 308P, 308N) may result in a significantly reduced defect rate during the re-crystallization process, thereby substantially reducing leakage currents in sophisticated transistor elements (200, 300N, 300P).
