Abstract:
1. A method of manufacturing an imprinting template using a semiconductor manufacturing process, comprising: providing a substrate; forming an oxide layer having a thickness in a range of 1000 angstroms to 8000 angstroms on the substrate; forming a photoresist layer on the oxide layer; performing a microlithography and etch process on the photoresist layer to form a pattern having a plurality of contact hole-like openings; etching the oxide layer through the openings to form a plurality of pillar-shaped holes; removing the photoresist layer; forming a barrier layer on surface of walls and bottoms of the pillar-shaped holes; depositing a material layer to fill up the pillar-shaped holes; performing a chemical mechanic polishing process to partly remove the material layer, thereby the height of the material layer is the same as the height of the oxide layer to expose the oxide layer; and partly removing the oxide layer to expose an upper part of the material layer to form a plurality of pillars, thereby forming an imprinting template.
