Physical Model for Surface Annihilation of Silicon Interstitials duringAnnealing

摘要：

Surface annihilation is the main mechanism through which implantation defects are annealed out from Si wafer. Surface annihilation possibility of silicon interstitials has obvious impact on total diffusion of dopant as well as junction depth. In this paper, a model on variation of surface annihilation possibility for silicon interstitials is proposed. By considering the surface annihilation rate and desorption rate and surface defect point, the analytical model for effective surface annihilation possibility is developed and verified. The impact of surface annihilation possibility on enhanced diffusion is simulated.
