Abstract:
1. A method to remove contaminants from a substrate surface of a semiconductor substrate, comprising: placing the semiconductor substrate in a cleaning apparatus having a carrier to hold the semiconductor substrate; dispensing a cleaning material to clean the contaminants from the substrate surface, the dispensing applied as a film over a length of the semiconductor substrate, wherein 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, wherein the plurality of solid components and the polymers are dispersed in the cleaning liquid, and wherein the plurality of solid component interact with at least some of contaminants on the semiconductor substrate surface to remove the contaminants from the substrate surface, 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; rinsing the film off of the semiconductor substrate with a rinsing meniscus, the rinsing meniscus applied along the length of the semiconductor substrate so that the film is rinsed after the dispensing; moving the carrier linearly so as to move the semiconductor substrate, the moving acting to dispense the cleaning material over new areas over the surface of the substrate, the moving further acting to apply the rinsing meniscus over the new areas of the surface of the semiconductor substrate; wherein the rinsing meniscus is applied at a separation from the dispensing of the cleaning material to allow the cleaning material to rest over the surface of the substrate before being removed with the rinsing meniscus.
