Edge bead removal for spin-on materials containing low volatility solvents using carbon dioxide cleaning |
| abstract |
Methods are provided for removing edge beads from spin-on films. A spin-on film is removed from a region of a surface of a spin-coated substrate adjacent to an edge of the surface by spinning the spin-coated substrate, expanding a fluid through a nozzle to form a cryogenic aerosol stream, and directing the cryogenic aerosol stream against the spin-on film in the region as the substrate spins. In another aspect of the invention, a film is formed on a surface of a substrate by dispensing a liquid composition onto the surface, spinning the substrate to distribute the liquid composition to form a substantially uniform film on the surface, expanding a fluid through a nozzle to form a cryogenic aerosol stream, and directing the cryogenic aerosol stream against the film in a region of the surface adjacent to an edge of the surface as the substrate spins. The film may include an alkoxysilane and a low volatility solvent. The fluid may consists essentially of liquid carbon dioxide. A spin-on film containing low volatility solvents does not grow back into the region from which the film was removed, the edge bead removal process time can be reduced to less than about 10 seconds, and the volume of waste solvent is reduced. |
