Methods for application of two-phase contaminant removal medium
Abstract:
A method is provided for receiving the wafer on a support, the support being configured for movement along a direction. While moving the wafer, dispensing a cleaning material to clean contaminants from the surface of the wafer, the dispensing applied as a film over a diameter length of the wafer. The cleaning material contains a cleaning liquid, a plurality of solid components, and polymers of a polymeric compound. Each of the plurality of solid components and polymers being greater than zero and less than 3% of the cleaning material, and wherein the polymers become soluble in the cleaning liquid and the solubilized polymers having long polymer chains that capture and entrap solid components and contaminants in the cleaning liquid. Then, rinsing the film off of the wafer with a rinsing meniscus. The rinsing meniscus applied along the diameter length of the wafer and the film is rinsed after the dispensing.
