摘要
Comparison of molecular implantation of SiF//3 and As//2 and their atomic constituents into semiconductors indicated that the molecular species amorphized to a depth 1. 2 to 2. 5 times greater than the atomic species. This effect resulted from selective molecular breakup due to collisions with residual gas atoms in the accelerator vacuum system, indicating the need for improved vacuum conditions in commercial ion implanters used for molecular implantation.
