Abstract:
A method for removing particles from a semiconductor wafer surface is disclosed. A wafer is being spun on a spin coater contained within a condensing environment. Liquid vapor is then infused into the condensing environment to allow some of the liquid vapor to be condensed onto a surface of the wafer on which particles may adhere while the wafer is being spun. Next, a set of light pulses is applied to the surface of the spinning wafer. Finally, an air stream is utilized to carry the particles off the surface of the wafer.
