    摘要: An apparatus for cleaning and conditioning the surface of a semiconductor substrate such as wafer includes a rotatable chuck, a chamber, a rotatable tray for collecting cleaning solution with one or more drain outlets, multiple receptors for collecting multiple cleaning solutions, a first motor to drive chuck, and a second motor to drive the tray. The drain outlet in the tray can be positioned directly above its designated receptor located under the drain outlet. The cleaning solution collected by the tray can be guided into designated receptor. One characteristic of the apparatus is having a robust and precisely controlled cleaning solution recycle with minimum cross contamination.

    摘要: The present invention provides a plating apparatus with multiple anode zones and cathode zones. The electrolyte flow field within each zone is controlled individually with independent flow control devices. A gas bubble collector whose surface is made into pleated channels is implemented for gas removal by collecting small bubbles, coalescing them, and releasing the residual gas. A buffer zone built within the gas bubble collector further allows unstable microscopic bubbles to dissolve.

    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.
