Resist Removal Walks a Tightrope
At the 32 nm technology node and beyond, the most critical front-end-of-line (FEOL) cleans are during ultrashallow junction (USJ) formation, with an International Technology Roadmap for Semiconductors' (ITRS) target of 0.3 Å/clean of silicon loss. Meeting this challenge is most difficult for resist removal following high-dose implants.
