Abstract

In this paper, the impact of the N₂ anneal on laser processed silicon was investigated using photoluminescence (PL) imaging through comparing the PL signal of laser processed samples before and after N₂ anneal. The samples capped with different dielectrics or without any dielectric (bare surface) prior to the laser processing were used, enabling the evaluation of the influence of the N₂ anneal on the defects caused both by laser thermal effect and by the existence of dielectrics. Generally, it was found that N₂ anneal is an effective way to reduce both the laser and dielectric induced defects.
