Abstract
A processing method for use in the fabrication of fabrication of nanoscale electronic, optical, magnetic, biological, and fluidic devices and structures, for filling nanoscale holes and trenches, for planarizing a wafer surface, or for achieving both filling and planarizing of a wafer surface simultaneously. The method has the initial step of depositing a layer of a meltable material on a wafer surface. The material is then pressed using a transparent mold while shining a light pulse through the transparent mold to melt the deposited layer of meltable material. A flow of the molten layer material fills the holes and trenches, and conforms to surface features on the transparent mold. The transparent mold is subsequently removed.
