Abstract
The disclosure relates to a method of aligning a set of patterns on a substrate, which includes depositing on the substrate's surface a set of silicon nanoparticles, which includes a set of ligand molecules including a set of carbon atoms. The method involves forming a first set of regions where the nanoparticles are deposited, while the remaining portions of the substrate surface define a second set of regions. The method also includes densifying the set of nanoparticles into a thin film to form a set of silicon-organic zones on the substrate's surface, wherein the first and the second set of regions have respectively first and second reflectivity values, such that the ratio of the second reflectivity value to the first reflectivity value is greater than about 1.1.
