a method of forming an electrical conductor , comprising forming electrically conductive segments incorporating electromigration - inhibiting plugs . a row of windows is formed in a planar surface and electromigraation - inhibiting material is deposited over the planar surface and into the windows to provide electromigration - inhibiting plugs in the windows . the plugs may be formed by depositing an electromigration - inhibiting liner in the windows and then depositing electrically conductive material to fill the windows . portions of either or both of the plugs and conductive segments are removed such that the plugs and conductive segments have a coplanar surface . the plugs may be formed in windows in an electrically conductive layer defining the conductive segments . embodiments of the method may be employed in manufacture of integrated circuit conductor .
