Abstract
According to one embodiment, there is provided a manufacturing method of a semiconductor device. The method includes forming a film to be processed on a substrate. The method includes forming a first resist pattern on the film, the first resist pattern having a first stepped structure including a plurality of steps. The method includes forming a second resist pattern on the first resist pattern by use of a template for nanoimprint. The second resist pattern has a second stepped structure, which is arranged corresponding to the first stepped structure and is formed such that a step-up surface extends perpendicularly to a flat surface. The method includes processing the film through the second resist pattern and the first resist pattern.
