摘要: A process is described for forming, over a silicon surface, titanium nitride barrier layer having surface of (111) crystallographic orientation. The comprises: depositing first surface; sputtering the layer; second sputtered and then annealing structure in presence nitrogen-bearing gas, absence an oxygen-bearing to form desired orientation sufficient thickness provide protection underlying against spiking aluminum. When aluminum subsequently formed oriented will assume same orientation, resulting enhanced resistance electromigration.
