发明名称 Method of controlling metal silicide formation
摘要 Methods of processing silicon substrates to form metal silicide layers thereover having more uniform thicknesses are provided herein. In some embodiments, a method of processing a substrate includes providing a substrate having a plurality of exposed regions comprising silicon, wherein at least two of the plurality of exposed regions have a different rate of formation of a metal silicide layer thereover; doping at least one of the exposed regions to control the rate of formation of a metal silicide layer thereover; and forming a metal silicide layer upon the exposed regions of the substrate, wherein the metal silicide layer has a reduced maximum thickness differential between the exposed regions.
