Abstract:
1. A method for expelling a gas positioned between a substrate and a mold assembly, the substrate and the mold assembly further having a liquid positioned therebetween, the method comprising the steps of: positioning the mold assembly and the substrate such that the mold assembly is proximate to the substrate, the mold assembly having a first region at a periphery of the mold assembly and a second region at a center sub-portion of the mold; altering a shape of the mold assembly by bowing the first region away from the substrate to bow the second region toward the substrate to decrease a gap defined between the second region of the mold assembly and the substrate; and contacting a sub-portion of the liquid with the second region of the mold assembly such that the gas expels from between the substrate and the mold assembly and the liquid fills a volume defined between the mold assembly and substrate.
