Overview

Triase+™ W is a 300mm single-wafer CVD system that delivers high step coverage tungsten (W) film deposition using WF6. By combining rapid heat up and cool down of wafer temperatures and with plasma-less chamber cleaning technology, the system achieves higher productivity and lower CoO. Utilizing SFD and CVD methods respectively, the Triase+™ W provides in-situ deposition of both nucleation and bulk film. This ensures high step coverage, even with small geometry, contact holes. The system is also capable of depositing low-resistance film to meet further scaling needs, and is suitable for such applications as contact plug formation and via filling.
