Abstract:
1. A micro-casted silicon carbide nano-imprinting stamp, comprising: a handling substrate; a glue layer connected with the handling substrate, wherein the glue layer comprises a material selected from the group consisting of tungsten, titanium, titanium nitride, cobalt, platinum, gold, a gold-tin alloy, silver, and a silicide; a foundation layer connected with the glue layer and including a base surface; and a plurality of nano-sized features connected with the foundation layer and extending outward of the base surface, the nano-sized features including an outer surface defining an imprint profile, the foundation layer and the nano-sized features are a micro-casted unitary whole and are made entirely from a material comprising silicon carbide, and wherein a hardness of the silicon carbide is operative to maintain the imprint profile of the nano-sized features over repeated engagements of the nano-imprinting stamp with a media to be imprinted.
