摘要:
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.

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.

A first resist film is formed on a substrate, and first pattern exposure is performed such that the first resist film is irradiated with exposure light through a first mask. Then, the first resist film is developed, thereby forming a first resist pattern out of the first resist film. Subsequently, a nano-carbon material is attached to the surface of the first resist pattern, and then a second resist film is formed on the substrate including the first resist pattern. Thereafter, second pattern exposure is performed such that the second resist film is irradiated with exposure light through a second mask. Then, the second resist film is developed, thereby forming a second resist pattern out of the second resist film.

A block copolymer film is formed on a substrate. Then, the block copolymer film is annealed in an inert-gas atmosphere, for example, in a neon atmosphere. This places the outside (mainly the upper portion) of the block copolymer film in a nonpolar state, thereby strongly drawing, for example, a monomer unit having hydrophobic characteristics outside the block copolymer film to accelerate self-assembly. This results in an improvement in throughput in self-assembled pattern formation of the block copolymer film.

A photomask includes: a transparent substrate having a transparent property against exposing light; a first light-shielding pattern formed on the transparent substrate and having a first dimension; a second light-shielding pattern formed on the transparent substrate and having a second dimension larger than the first dimension; and an opening provided in part of the transparent substrate where the first light-shielding pattern and the second light-shielding pattern are not formed. The first light-shielding pattern includes a first semi-light-shielding portion and an auxiliary pattern which is arranged within the first semi-light-shielding portion and allows the exposing light to pass through in an opposite phase with respect to the first semi-light-shielding portion. The second light-shielding pattern includes a second semi-light-shielding portion and a light-shielding portion which does not substantially allow the exposing light to pass through.

A resist film is formed on a substrate, and a barrier film including a compound whose alkali-insoluble property is changed to an alkali-soluble property through molecular structure change caused by an alkaline solution is formed on the resist film. Thereafter, with an immersion liquid provided on the barrier film, pattern exposure is performed by selectively irradiating the resist film through the barrier film with exposing light. After the pattern exposure, the barrier film is removed and the resist film is developed. Thus, a resist pattern made of the resist film is formed.

A resist film is first formed on a substrate. Subsequently, a barrier film including a basic compound of, for example, dicyclohexylamine is formed on the resist film. Thereafter, with an immersion liquid including cesium sulfate 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 in a good shape.

In a pattern formation method, a resist film is formed on a substrate, an alkali-soluble first barrier film is formed on the resist film and an alkali-insoluble second barrier film is formed on the first barrier film. Subsequently, with a liquid provided on the second barrier film, pattern exposure is performed by selectively irradiating the resist film with exposing light through the second barrier film and the first barrier film. Then, after removing the second barrier film, the resist film having been subjected to the pattern exposure is developed, so as to remove the first barrier film and form a resist pattern made of the resist film.
摘要:
In a pattern formation method, a resist film is formed on a substrate and a barrier film including a plasticizer is then formed on the resist film. Thereafter, with a liquid provided on the barrier film, pattern exposure is carried out by selectively irradiating the resist film with exposing light through the barrier film. Subsequently, after the pattern exposure, the resist film is developed after removing the barrier film, so as to form a resist pattern in a good shape without producing residues.
