Abstract
Self aligned CuGeN barriers are used to improve the adhesion of Cu/SiC(N) interfaces at N45 technology. Eight times of electro-migration (EM) lifetime improvement has been demonstrated using thin CuGeN as a capping layer. Less than 5% metal lines Rs increase with a thin CuGeN capping layers were achieved at TSMC N45 node. CuGeN have more uniform films are the key to achieve low Rs increase successfully, which are important to N32/N22 and beyond technology.
