大綱: 1. Fundamental of Surface Cleaning Technology 2. Challenge and Solution of Particle Removal - defect adhesion vs. removal (scrubber, megasonic, hydrodynamics, aerosl etc.) 3. Cleaning Process Equipments - tool, monitor, non-conventional cleaning - wafer rinse/ dry technology- the deep trench application 4. Fundamental and Application of Wet Chemistries - APM, HF/ BOE-- surface condition and water mark etc. 5. Wet Etching Processes: - selective oxide/ nitride etch; poly, dielectric and metal stripper etc. 6. Applications of FEOL Wet Processes - HPM, SPM, pre-furnace clean—impact of roughness on electrical characteristics - Post implement/ etch PR strip—surface condition, Salicide selective etch 7. Application of BEOL Post Ash Cleaning - Solvent base PAC / Dilute acid PAC- galvanic effect and metal corrosion etc. 8. Challenges and Solution of nm Devices Cleaning Processes - Fragile/ HAR patterns- STI/ gate, spacer, contact/via clean - high K/ metal gate, MUG/ FIN FET, mobility engineering etc. 9. Summary
