摘要： A method for cleaning semiconductor substrate using ultra/mega sonic device comprising holding a semiconductor substrate by using a chuck, positioning a ultra/mega sonic device adjacent to the semiconductor substrate, injecting chemical liquid on the semiconductor substrate and gap between the semiconductor substrate and the ultra/mega sonic device, changing gap between the semiconductor substrate and the ultra/mega sonic device for each rotation of the chuck during the cleaning process. The gap can be increased or reduced by 0.5λ/N for each rotation of the chuck, where λ is wavelength of ultra/mega sonic wave, N is an integer number between 2 and 1000. The gap is varied in the range of 0.5λn during the cleaning process, where λ is wavelength of ultra/mega sonic wave, and n is an integer number starting from 1.

摘要： This invention relates to a method and apparatus by integrating semiconductor manufacturing processes of stress free electrochemical copper polishing (SFP), removal of the Tantalum oxide or Titanium oxide formed during SFP process and XeF2 gas phase etching barrier layer Ta/TaN or Ti/TiN process. Firstly, at least portion of plated copper film is polished by SFP. Secondly the barrier metal oxide film formed during SFP process is etched away by etchant. Finally, the barrier layer Ta/TaN or Ta/TiN is removed with XeF2 gas phase etching. The apparatus accordingly consists of three sub systems: stress free copper electropolishing system, barrier layer oxide film removal system and barrier layer Ta/TaN or Ti/TiN gas phase etching system.
