With the development of urbanization, the underground pipelines play an important role in ensuring the basic conditions of citizen life. However, construction activities are continuously increasing in the mainland of China nowadays, which lead to serious damages and threatens to the underground pipelines by excavation equipment. To this end, we focus on developing an automatically monitoring system...
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...
