摘要: A method for performing a CMOS Image Sensor (CIS) silicide process is provided to reduce pixel contact resistance. In one embodiment, the method comprises forming a Resist Protect Oxide (RPO) layer on the CIS, forming a Contact Etch Stop Layer (CESL), forming an Inter-Layer Dielectric (ILD) layer, performing contact lithography/etching, performing Physical Vapor Deposition (PVD) at a pixel contact hole area, annealing for silicide formation at pixel contact hole area, performing contact filling, and defining the first metal layer. The Resist Protect Oxide (RPO) layer can be formed without using a photo mask of Cell Resist Protect Oxide (CIRPO) photolithography for pixel array and/or without silicide process at pixel array. The method can include implanting N+ or P+ for pixel contact plugs at the pixel contact hole area. The contact filling can comprise depositing contact glue plugs and performing Chemical Mechanical Polishing (CMP).
