Patent ID: 8012667

Claim:
A soft mold, comprising: a UV light cured product of a resin layer, the resin layer including a photo-curable material; and a photo-initiator combined with the photo-curable material wherein the soft mold is treated in a post-treatment process using UV light such that each surface of the soft mold satisfies an equation ( 0.3 × γ M d γ L ) 1 / 2 + ( 0.7 × γ M p γ L ) 1 / 2 ≤ 0.5 , wherein γ d M is a dispersion term of a surface energy of the soft mold, γ p M is a polar term of a surface energy of the soft mold, and γ L is a surface energy of deionized water. wherein the photo-curable material is one or more selected from diethylene glycol dimethacrylate (DGDMA), ethylene glycol dimethacrylate (EGDMA), ethylene glycol phenyletheracrylate (EGPEA), 2-ethoxy-(2-ethoxy)ethyl acrylate (EOEOEA), 1,6-hexanediol (EO) diacrylate (HD(EO)DA), polyurethane acrylate, glycidyl acrylate, or butyl methacrylate.
