Patent ID: 7062850

Claim:
A method for forming an electrical conductor, comprising: forming electrically conductive segments; forming a row of windows in a planar surface, wherein each window is separated from an adjacent window by a distance that is equal to or less than a predetermined critical length, L c , selected to inhibit electromigration; depositing electromigration-inhibiting material over the planar surface and into the windows to provide electro-migration inhibiting plugs in said windows; said plugs interposed between and abutting neighboring electrically conductive segments to connect and space neighboring segments by a distance significantly less than the length of a segment; and removing portions of either or both of said plugs and said conductive segments such that said plugs and conductive segments have a coplanar surface; wherein the conductor has a length, L, that is greater than the critical length, L c , and wherein the row includes a number of windows is equal to or more than (L/L c )−1.
