Abstract
Various embodiments of the present technology generally relate to substrate planarization. More specifically, some embodiments of the present technology relate a versatile systems and methods for precision surface topography optimization known as planarization on nominally planar substrates. In some embodiments, a method for planarization of a patterned substrate using inkjets can determine the global and nanoscale topography and pattern information of the patterned substrate. Based upon the global and nanoscale topography and pattern information, a drop pattern can be determined and then dispensed on the patterned substrate. A gap between the patterned substrate and a superstrate causing the dispensed drops can be closed to form a substantially contiguous film. The substantially contiguous film can be cured and the superstrate can be separated from the patterned substrate with substantially contiguous film on the patterned substrate.
