| abstract |
One illustrative method disclosed herein includes, among other things, forming an opening in at least one layer of insulating material so as to thereby expose at least a portion of a conductive contact, performing a selective metal silicide formation process to selectively form a metal silicide layer in the opening and on the conductive contact, depositing at least one conductive material above the selectively formed metal silicide layer so as to over-fill the opening, and performing at least one planarization process so as to remove excess materials and thereby define a conductive via that is positioned in the opening and conductively coupled to the selectively formed metal silicide layer and to the conductive contact. |
