Planar FinFet and beyond- Newer device structures tighter wafer specs and control
- Key wafer parameters and related fab signals There is still lot of room for improvement
- Future challenges to wafer manufacturers Are we are currently flying blind ? Think Differently

Fab Strategy
Focus on two key wafer parameters(a) Incoming wafer PC (b) Wafer Flatness
- Both included in wafer related ITRS Roadmap- Both behind what advanced nodes need as per ITRS*
ITRS Roadmap for critical particle size
ITRS Roadmap for wafer site flatness
* ITRS standards are referred here as a guide for bare wafers but in reality specs requirements are even tighter than that.

Critical Wafer Quality: FlatnessPhoto leveling dependence on wafer edge flatness
Work in Progress
Fab: Identify and understand critical wafer quality parameters dependence on fab performance, feedback to vendor for quality improvement
Vendor: Identify process knobs to achieve the desired improvement

Challenges to Wafer Vendor
Defect on High flyerwafers post pad films
Incoming CoA not catching wafer related defects.
- 50nm PC spec obsolete for advanced nodes. - Need to monitor and spec lower PC bins
- Which pc size is appropriate ? 37nm, 26nm, 19nm ?- Vendors need to install SP5 capability and capacity.
Challenge: Install appropriate PC monitoring capability and capacity for advanced nodes ?

Challenges to Wafer Vendor
Monitoring traditional wafer quality parameters is not enough.- Monitor chemical oxide thickness ?
Use non-traditional techniques like deposition of decoratingfilms to monitor and improve wafer quality
Challenge: Monitor non-traditional wafer parameters, Use non traditional techniques to improve quality

Challenges to Wafer VendorWafer Vendor raw material/site matching Impact on Quality
- How well do you monitor incoming chemical quality ?- How well do you monitor site UPW quality ?- Do you have the right chemical quality monitoring capability?- Tool to tool matching or manufacturing line to line matching ?
Challenge: Think like a HVM Fab
