Low-resistance wiring and 2Xnm void-free fill with CVD ruthenium liner and direct seed copper

01/06/2011 

Direct seed copper for semiconductor fabricationJonathan Rullan et al compare resistance from chemical vapor deposited (CVD) ruthenium liners and direct seed (DS) copper used with advanced Electrofill processes to conventional methods, using different annealing temps and simulated back-end-of-line (BEOL) thermal stress builds. 2X nm trenches were shown to have complete gap fill, eliminating the need for conventional PVD Cu seed.
