Claim:
1. A pattern forming method for forming a pattern using a near-field exposure mask manufactured by a manufacturing method, the manufacturing method of the near-field exposure mask comprising: forming a resist layer on a first substrate; forming a resist pattern on the first substrate by using a lithography, the resist pattern having lines and spaces; depositing a near-field light generating film on the resist pattern to fill the near-field light generating film in the spaces of the resist pattern; polishing the near-field light generating film to expose an upper surface of the resist pattern and forming a near-field light generating film pattern, the near-filed light generating film pattern having lines and spaces; and removing remaining parts of the resist pattern on the first substrate, the pattern forming method comprising: applying a light-curable resin on a second substrate; pressing the near-field exposure mask against the light-curable resin; injecting light to a side of the second substrate; causing the light-curable resin to react to near-field light generated from the near-field light generating film pattern to generate first portions of the light-curable resin in which the near-field light is generated and second portions of the light-curable resin in which no near-field light is generated, the near-field light being generated by the injected light; detaching the near-field exposure mask from the second substrate; removing the first portions of the light-curable resin and remaining the second portions of the light-curable resin on the second substrate; and etching the second substrate using the second portions of the light-curable resin.
