  • Patent number: 9017930
    Abstract: 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.

  • Publication number: 20120127454
    Abstract: According to one embodiment, a pattern including first and second block phases is formed by self-assembling a block copolymer onto a film to be processed. The entire block copolymer present in a first region is removed under a first condition by carrying out energy beam irradiation and development, thereby leaving a pattern including the first and second block phases in a region other than the first region. The first block phase present in a second region is selectively removed under a second condition by carrying out energy beam irradiation and development, thereby leaving a pattern including the first and second block phases in an overlap region between a region other than the first region and a region other than the second region, and leaving a pattern of second block phase in the second region excluding the overlap region. The film is etched with the left patterns as masks.

  • Patent number: 8101516
    Abstract: A block film is formed on a region which includes a region of an insulating layer where a first hole is to be formed, and in which no second hole is to be formed, and a resist film having openings for forming the first and second holes is formed on the block film and insulating layer. Etching is performed by using the resist film as a mask, thereby forming the first hole in the block film and insulating layer, and the second hole in the insulating layer. The depth of the first hole from the upper surface of the insulating layer is smaller than that of the second hole, so the first hole does not reach the semiconductor substrate.
