Abstract:
1. A method of forming a transistor, said transistor having a gate structure comprised of a conductive material and a source/drain region, comprising: forming at least one layer of insulating material above said source/drain region; performing at least one etching process to form a contact opening in said at least one layer of insulating material above at least a portion of said source/drain region; wherein, after the completion of said etching process, a portion of said gate structure is exposed; selectively forming an oxidizable material on at least a portion of said exposed gate structure; after selectively forming the oxidizable material, performing an oxidation process to convert at least a portion of said oxidizable material to an oxide material; and forming a conductive contact in at least said contact opening that is conductively coupled to said source/drain region.
