摘要
The process of manufacturing copper damascene metallization for integrated circuits involves a series of interrelated process steps including dielectric deposition and etching, PVD barrier/seed layer deposition, feature filling by bottom-up electroplating ("electrofilling"), annealing, edge bevel copper removal, and chemical mechanical polishing. In this paper we discuss the interrelationship between the properties of the PVD seed layer, electroplating processes and plating bath additives in achieving void-free electrofill of high aspect ratio structures.
