Photo Nano-Imprint Lithography (P-NIL)

UV or photo nano-imprint lithography (UV-NIL or P-NIL) is a versatile method for low-cost nano-scale device fabrication.   A resin is coated on a substrate, a stamper with patterns is pressed on, and the resin is cured by UV light as illustrated below.  The method gives embossed features on plastic, glass, silicon, or metal for many applications including optical storage, displays, semi-conductor devices.  ACW provides low viscosity, high hardness, high Tg, and optically clear resins for accurate nano-scale replications.
