摘要: A method for forming a semiconductor device structure is provided. The method includes providing a wafer having a central portion and a peripheral portion surrounding the central portion. The method includes forming a first dielectric layer over the central portion. The first dielectric layer has first contact openings exposing conductive regions of the wafer. The method includes forming a protective layer over the peripheral portion. The method includes after forming the protective layer, performing a metal silicide process to form metal silicide structures over the conductive regions of the wafer.
