Abstract:
1. A method of altering an integrated circuit structure, said method comprising: supplying an integrated circuit structure comprising at least one first-type field effect transistor and at least one second-type field effect transistor, said first-type field effect transistor and said second-type field effect transistor each comprising source and drain regions, a channel region between said source and drain regions, a gate conductor adjacent said channel region, a gate insulator between said channel region and said gate conductor, and a first-type silicide layer on said gate conductor and said source and drain regions; patterning a protective layer over said first-type field effect transistor; removing at least a portion of said first-type silicide layer from said second-type field effect transistor; and forming a second-type silicide layer on said gate conductor and said source and drain regions of said second-type field effect transistor, said second-type silicide layer being different than said first-type silicide layer.
