Abstract:
1. A pattern forming method comprising: forming a pattern film on a face of a first substrate, the face of the first substrate being substantially flat, the pattern film having a first pattern, the first pattern having first concave portions and first convex portions, the pattern film comprising a material containing a first to-be-imprinted agent; forming a material film on a second substrate, the material film containing a second to-be-imprinted agent having a higher etching rate than an etching rate of the first to-be-imprinted agent; applying pressure between the first substrate and the second substrate, with the pattern film being positioned to face the material film, and curing the second to-be-imprinted agent to form a second pattern having second concave portions and second convex portions in the material film, with each of the first convex portions fitting a corresponding one of the second concave portions and each of the second convex portions fitting a corresponding one of the first concave portions; detaching the first substrate from the pattern film and leaving the first pattern on the second pattern; and etching the second convex portions to leave the first pattern on the second substrate.
