Abstract
Evolution of extended defects during annealing of MeV ion-implanted p-type Si has been characterized using deep level transient spectroscopy and transmission electron microscopy. The p-type Si was implanted with Si, Ge, and Sn ions with varying energies and doses from 5×10¹² to 1×10¹⁴ cm⁻² then annealed at 800 °C for 15 min. For all implanted species, the critical dose for transformation from point to extended defects has been determined. The type of extended defects formed depends upon the mass of the implanted species even though the dose was adjusted to create a similar damage distribution for all implanted species.
