This paper reports a novel pattern transfer method which can transfer two patterned metal films from one single mold to two separate polymer substrates. The first metallic film is defined by the top convex surface of a silicon mold and is transferred to a polymer substrate directly from roller-assisted contact printing and infrared heating. The second metallic film, which is defined by the bottom...
In this paper we report the fabrication of metallic nano-wired polarizer on polymer substrate based on infrared assisted and roller based direct metal contact transfer technology. This method effectively resolves several serious problems in conventional hot-embossing types of nano-imprinting such as uniformly applied pressure and thermal deformation of the flexible substrate due to over heating. In...
This paper presents a new roller-based nano-imprinting method based on the Infrared assisted metal transfer technique. It utilizes a silicon mold which is deposited with a thin metal film for pattern transferring. Another metal film which acts as an adhesion layer is also deposited on the substrate surface. An infrared light source incident from the substrate side heats up the metal films. After imprinting,...
