  • Publication number: 20090227111
    Abstract: A resist film made of a chemically amplified resist is formed on a substrate. Subsequently, a barrier film for preventing a component of the resist film from eluting into an immersion liquid or preventing the immersion liquid from permeating into the resist film is formed on the resist film. Thereafter, with an immersion liquid provided on the barrier film, pattern exposure is carried out by selectively irradiating the resist film with exposing light through the barrier film. Then, after removing the barrier film, the resist film having been subjected to the pattern exposure is developed, so as to form a resist pattern made of the resist film.

  • Publication number: 20090186484
    Abstract: After forming a resist film made from a chemically amplified resist material pattern exposure is carried out by selectively irradiating the resist film with exposing light while supplying, onto the resist film, water that includes triphenylsulfonium nonaflate, that is, an acid generator, and is circulated and temporarily stored in a solution storage. After the pattern exposure, the resist film is subjected to post-exposure bake and is then developed with an alkaline developer. Thus, a resist pattern made of an unexposed portion of the resist film can be formed in a good shape.

  • Publication number: 20090092930
    Abstract: After forming an underlying layer film and an intermediate layer film are formed over a substrate, a resist pattern formed by first pattern exposure using a first resist film and second pattern exposure using a second resist film is transferred onto the intermediate layer film. Furthermore, the underlying layer film is etched using the intermediate layer pattern as a mask, thereby obtaining an underlying layer film pattern. The underlying layer film includes as an adduct a fluorine-based surfactant or inorganic nano particles and is provided with a resistance against oxygen-based plasma.

  • Publication number: 20080233491
    Abstract: A barrier film material includes, in addition to an alkali-soluble polymer, a multivalent carboxylic acid compound having a plurality of carboxyl groups or a multivalent alcohol compound. Thus, the multivalent carboxylic acid compound or the multivalent alcohol compound is adhered onto the surface of a resist film, and hence, particles having been adhered to the surface of the resist film are removed in removing the barrier film. Also, in the case where the barrier film is removed simultaneously with development, the resist film can be prevented from remaining partly undissolved.

  • Publication number: 20080227038
    Abstract: After formation of an underlayer film and an intermediate layer film, a resist pattern formed by the first pattern exposure with the first resist film and the second pattern exposure with the second resist film is transferred to the intermediate layer film. The underlayer film is etched using an intermediate layer pattern as a mask to form an underlayer film pattern. Herein, the first and second resist films are chemically amplified resist films. The second resist film contains a greater amount of additive which improves the sensitivity of the resist or which improves the alkaline solubility of resist exposed part.
