A method for fabricating a mold core ( 30 ) includes the following steps: mixing a silicone elastomer with a curing agent (S 901 ); defoaming bubbles of the mixture (S 902 ); forming a layer ( 10 ) of the mixture on a substrate ( 20 ) having a predetermined surface structure formed thereon (S 903 ); curing the layer of the mixture (S 904 ); and separating the cured layer from the substrate to provide the mold core (S 905 ). Unlike in the prior art, there is no need for steps of forming a photo-resist pattern, forming a Cu layer, and/or etching the Cu layer off. Thus, the method of the present invention has reduced complexity and costs compared with the method of the prior art. In addition, the obtained structure of the mold core corresponds more closely to the predetermined structure of the substrate. That is, the precision of the mold core is significantly increased.
