Abstract

Semiconductor devices and methods of fabricating the same are provided. The methods include preparing a template having a three dimensional (3D) stair type structure formed in intaglio, forming an imprint pattern having the stair type structure using the template, and simultaneously forming stair type patterns on a substrate using the imprint pattern.
