摘要

We have developed a 50 A IMP Ti film for 300mm liner application. The process development was done on 300 mm iLB Endura Platform, which combines the high bottom converage andscalability of IMP Ti with the conformility of the CVD TXZ TiN process to address low contact resistance and good adhesion for W and Al application. The IMP technology has an advantage of significant imporving the step coverage but has a limitation on obtaining a good film uniformity due to high pressure operation and coil supttering non-uniformity. ICE technology was used to improve the coil sputtering non-uniformity and film uniformty was improved to approx 4
