SALICIDE PROCESS USING CAPPING LAYER WITH DOUBLE LAYER STRUCTURE
A method for forming a salicide using a capping layer of a duplex structure is provided to prevent the malfunction of a semiconductor device by restricting current leakage such as GIDL in a high voltage gate structure by using a titanium nitride layer as the capping layer. In a salicide process for...
