Method of forming a microstructure

摘要

The present invention relates to a method of forming a microstructure comprising, providing a transparent substrate having a structured surface region comprising one or more recessed features with recessed surfaces, the structured surface region substantially free of plateaus; disposing a fluid conductive ink composition comprising a functional material and a liquid onto the structured surface region; evaporating liquid from the fluid composition, the functional material collecting on the recessed surfaces such that the remainder of the structured surface region is substantially free of the functional material, wherein the functional material comprises conductive polymer, metal, or a combination thereof; and backfilling the recessed features with a transparent refractive index matching material.
