Abstract

Official abstract text for this publication.

According to one embodiment, a pattern formation method includes forming a pattern on a layer. The layer has a first surface energy and includes a silicon compound. The pattern has a second surface energy different from the first surface energy. The method includes forming a block polymer on the layer and the pattern. The method includes forming a structure selected from a lamellar structure and a cylindrical structure of the block polymer containing polymers arranged by microphase separation. The lamellar structure is oriented perpendicularly to the layer surface. The cylindrical structure is oriented so as to have an axis parallel to a normal line of the layer surface. The second surface energy is not less than a maximum value of surface energies of the polymers or not more than a minimum value of the surface energies of the polymers.

First claim

Opening claim text (preview).

What is claimed is: 1. A pattern formation method comprising: forming an organic film on a film to be processed; forming a layer having a first surface energy and comprising a silicon compound on the organic film; forming a pattern, which has a second surface energy different from the first surface energy, on the layer using a photosensitive material pattern formed by light; forming a block polymer on the layer and the pattern; forming a structure selected from the group c…
