According to a method for forming a pattern in one embodiment, a first pattern is formed on a substrate, and an upper part of the first pattern is irradiated with ultraviolet rays, to enhance a liquid-repellent property to an inversion resin material. Furthermore, according to the method for forming the pattern, the inversion resin material is applied to the substrate after the irradiation of the ultraviolet rays, the first pattern is removed after the inversion resin material has been applied to form a second pattern containing the inversion resin material, and the substrate is processed using the second pattern as a mask.
