Patent ID: 8764431

Claim:
An apparatus for transcripting fine patterns, comprising: a resist application unit which applies resist to both sides of a substrate; an exposure unit which presses two stampers that make a pair with fine patterns formed therein against both sides of the substrate with resist applied to both sides thereof by the resist application unit and exposes the resist applied to both sides of the substrate with light and thereby transcripts the patterns formed in the two stampers to the resist; a substrate unloading unit which breaks the substrate away from one of the two stampers pressed against both sides of the substrate with the patterns transcripted to both sides thereof and unloading the substrate from the exposure unit together with the other of the two stampers; and a breakaway unit which receives the substrate unloaded from the exposure unit by the substrate unloading unit and breaks the substrate away from the other stamper, wherein the exposure unit includes: two stamper deforming means that make a pair respectively deforming the two stampers into a convex shape and releasing the convex shape deformation; two stamper driving means that make a pair respectively advancing or retreating the two stampers in a direction perpendicular to both sides of the substrate with the resist applied to both sides thereof; and two exposure means which expose both sides of the substrate with the resist applied to both sides thereof with UV light emitted from LEDs passed through each of the two stampers pressed against both sides of the substrate by the two stamper driving means, wherein each of the two stamper deforming means corresponds to one of the two stampers, and wherein at least one of the two stamper deforming means corresponding to one of the two stampers includes: an evacuation part which evacuates a space on an opposite side to a surface of the one of the two stampers opposed to the substrate; a first elastic member which supports the vicinity of a peripheral area of a surface of the one of the two stampers on the opposite side to the side where the one of the two stampers is opposed to the substrate with the space evacuated by the evacuation part; and a second elastic member which supports the vicinity of a central area of the surface of the one of the two stampers on the opposite side to the side where the one of the two stampers is opposed to the substrate with the space evacuated by the evacuation part.
