Abstract:
1. A method for forming a pattern comprising: providing a substrate having an etching target layer thereon; preparing a resist ink composed of 70% or less by weight of solvent, 10-15% by weight of base polymer, 10-15% by weight of tacktifier, 3% or less by weight of additive, and 1-10% by weight of silane coupling agent; forming the resist ink onto a roll; rotating the roll having the resist ink in a contact state with a cliché having convex patterns and removing the resist ink contacted with the convex patterns from the roll to form resist patterns on the roll surface; rotating the roll on the substrate to transcribe the resist patterns onto the etching target layer; baking the transcribed resist patterns; and etching the etching target layer by using the resist patterns, wherein the solvent includes carrier solvent and printing solvent mixed in the ratio of 9:1.
