Patent ID: 8461048

Claim:
A fabrication method of a minute pattern, comprising: forming a first crystallizable material layer on a substrate; forming a patterned photoresist layer on the first crystallizable material layer, the patterned photoresist layer having a plurality of openings, the openings exposing a portion of the first crystallizable material layer; removing the exposed portion of the first crystallizable material layer with use of the patterned photoresist layer as a mask, so as to form a plurality of first patterns on the substrate, wherein a distance between every two adjacent first patterns of the first patterns is greater than a width of each of the first patterns; performing a first treatment process on the first patterns to crystallize the first patterns; forming a second crystallizable material layer on the substrate, the second crystallizable material layer covering the first patterns; and patterning the second crystallizable material layer to form a plurality of second patterns on the substrate, wherein each of the second patterns is respectively located between the first patterns adjacent thereto.
