Abstract:
A process for fabricating a non-gap 3-D microstructure array mold core, said process comprising the following steps of:(a) preparing a substrate; (b) coating on the substrate a high molecular buffer layer; (c) coating a photomask layer on the high molecular buffer layer; (d) forming a pattern of the photomask layer by lithography; (e) preparing a reflow by heating the patterned photomask layer at a temperature higher than the glass transformation temperature of a composite of which the photomask layer is formed, thereby resulting in formation of a microstructure array having a plurality of spaced apart microstructures; (f) cooling the microstructure array; (g) coating uniformly a metal conductive layer on the spaced apart microstructures of the microstructure array; and (h) eliminating microgaps of the microstructure array by coating the microstructure array with an electro-casting layer.
