Abstract
Oxide voiding is eliminated was substantially reduced by laser thermal annealing. Embodiments include fabricating flash memory devices by depositing a BPSG over spaced apart transistors as the first interlayer dielectric with voids formed in gaps between the transistors and laser thermal annealing the BPSG layer in flowing nitrogen to eliminate or substantially reduce the voids by reflowing the BPSG layer.
