Patent ID: 8883405

Claim:
A method for forming a pattern comprising: forming a lower layer film above a subject, the lower layer film including a photosensitive material; forming a resist film, on the lower layer film; dispersing the photosensitive material into the resist film from the lower layer film, and providing a concentration profile to the resist film, the concentration profile having a concentration of the photosensitive material being higher on a side of a bottom of the resist film than on a side of a surface of the resist film, a portion of the resist film having a maximum concentration of the photosensitive material existing closer to the side of the bottom than a center between the bottom and the surface of the resist film; irradiating the resist film having the concentration profile of the photosensitive material with a light from the side of the surface; and developing the resist film after the resist film being irradiated with the light.
