Claim:
A method of fabricating a soft mold, comprising: providing a master plate having depressed or embossed portions formed at a region corresponding to a pattern desired to be formed on a soft mold; coating a hydrophilic resist material containing an acrylate prepolymer of 96 wt % or greater, a photoinitiator of about 1 wt % to 3 wt %, and a surface active agent of about 0.01 wt % to 1 wt % on the master plate; attaching a back-plane including an attachment material to the hydrophilic resist material such that the attachment material contacts the hydrophilic resist material after coating the hydrophilic resist material on the master plate; curing the hydrophilic resist material by irradiating ultraviolet (UV) light to the hydrophilic resist material; and detaching the cured hydrophilic resist material from the master plate, wherein the soft mold comprises the cured hydrophilic resist material.
