Abstract

A method for forming a semiconductor structure includes forming a gate structure on a substrate, performing a deposition process to form a nitride layer to cover the substrate and the gate structure, performing an in-situ annealing process to the nitride layer, and performing an anisotropic etching process to the nitride layer after the in-situ annealing process to form a spacer on a sidewall of the gate structure.
