As dimension shrinks the volume percent occupied by conventional barrier and liner increases and line resistance (Rs) and via resistance (Rc) increases dramatically. An ultrathin ALD MnN barrier is being evaluated as a single layer barrier for resistance reduction in small structures. >20% and >80% Rs and Rc reduction was demonstrated, while 4× better mean time to failure (MTTF) on the time...
In recent years, the cellular formation is attended with the increasingly fierce market competition, diversification and personalization of product demand and delivery conditions. Many researchers have put forward cell reconfiguration to meet the different demand in each period, but they don't consider the product can be processed in different routes in the same period to decrease the reconfiguration...
This study reports the effect of different barrier on Cu interconnect performance. A thin “enhancement” layer of Ru or Co film is deposited between a PVD Ta(N) liner barrier and a Cu seed layer to improve copper to barrier adhesion and copper gap fill. With the enhancement layer of either Ru or Co, no void is found in dual damascene structure with very thin seed. The electrical performance is improved...
