    摘要: In a pattern formation method of this invention, a resist film is formed on a substrate and pattern exposure is performed by selectively irradiating the resist film with exposing light. Subsequently, the resist film is developed after the pattern exposure, and the developed resist film is rinsed with an aqueous solution including cyclodextrin.
    Methods are also disclosed involving either developing with a solution including cyclodextrin or rinsing with an aqueous solution including a surfactant.
    Thus a fine resist pattern made of the resist film is formed without causing pattern collapse.

    摘要: After forming a TiN film on a semiconductor substrate, a surface treatment agent in a gas phase, which is obtained by bubbling trimethylsilyl methylsulfonate with a nitrogen gas, is supplied onto the TiN film. The TiN film is then coated with a chemically amplified positive resist including an acid generator and a compound which can attain alkali solubility through the function of an acid, and a pre-bake process is subsequently conducted, thereby forming a resist film. The resist film is then exposed with a KrF excimer laser by using a desired mask. Through this exposure, an acid is generated from the acid generator included in the resist film. Since sulfonic acid produced from trimethylsilyl methylsulfonate weakens the function as a base of a nitrogen atom having a lone pair, the acid generated from the acid generator is not deactivated at the bottom of the resist film. As a result, a resist pattern with a satisfactory shape free from footing can be formed.

    摘要: A resist film is formed on a semiconductor substrate by using a chemical amplification resist which generates a base in response to the radiation of KrF excimer laser light and which reacts with the base. If the resist film is irradiated with the KrF excimer laser light through a mask, the base is generated in the surface of an exposed portion of the resist film, so that the surface of the exposed portion is made hydrophilic by the base. If water vapor is supplied to the surface of the resist film, water is diffused from the surface of the exposed portion into a deep portion. If vapor of e.g. methyltriethoxysilane is sprayed onto the surface of the resist film in air at a relative humidity of 95%, an oxide film with a sufficiently large thickness is selectively formed on the surface of the exposed portion.

    摘要: In a clean room, after conducting a surface treatment on the surface of a semiconductor substrate with 4-trimethylsiloxy-3-penten-2-one, the treated surface of the semiconductor substrate is coated with a chemically amplified resist, thereby forming a first resist film. Then, the first resist film is successively subjected to exposure, PEB and development, thereby forming a first resist pattern of the chemically amplified resist. Next, in the same clean room, after conducting a surface treatment on the surface of the semiconductor substrate with 4-dimethyl-n-hexylsiloxy-3-penten-2-one, the treated surface of the semiconductor substrate is coated with a non-chemically amplified resist, thereby forming a second resist film. Then, the second resist film is successively subjected to the exposure, the PEB and the development, thereby forming a second resist pattern of the non-chemically amplified resist.

    摘要: An improved semiconductor device fabrication technique is disclosed. A resist layer, composed of a chemical compound which generates an acid when exposed to energy light and a resin which contains protecting groups that are removed from the resin by acid, is formed on top of a semiconductor substrate. The resist layer is subjected to a lithography and a development process and is formed into a resist pattern. This resist pattern is exposed to ultraviolet beams, and the chemical compound generates an acid and the protecting groups are removed from the resin. As a result of such an elimination reaction, the surface of the resist pattern becomes coarse. Thereafter, an implant of ions is carried out to the semiconductor substrate using the resist pattern as a mask. The surface of the semiconductor substrate is cleaned using a cleaning solution, and the resist pattern with a coarse surface can easily and completely be removed from the semiconductor substrate.

    摘要: The composition of a resist material is determined so that the film thinning quantity of the resist pattern is increased when the profile of a resist pattern which is formed in advance tends to be a T-top profile as compared with a reference pattern profile but so that the film thinning quantity of the resist pattern is decreased when the profile of the resist pattern which is formed in advance tends to be a round-shoulder profile as compared with the reference pattern profile. After coating a semiconductor substrate at its top with the resist material whose composition is determined as such to thereby form a resist film, the resist film is exposed through a mask. The exposed resist film is developed, whereby a resist pattern is obtained.

    摘要: A first correlation is obtained which is a correlation between latent image height produced after exposure on a resist layer, and resist pattern linewidth for a given length of develop time. Additionally, a second correlation is obtained which is a correlation between develop time for each exposure energy dose and resist pattern linewidth. The height of a latent image produced on an actually exposed resist layer is determined. From the first correlation, an estimated resist pattern linewidth, which is a resist pattern linewidth corresponding to a latent image height and to a given length of develop time, is found. From the second correlation, an estimated exposure energy dose, which is an exposure energy dose corresponding to a given length of develop time and to an estimated resist patten linewidth, is found. Additionally, also from the second correlation, develop time corresponding to a target resist pattern linewidth and to an estimated exposure energy dose is found, and according to the develop time found, a resist pattern is formed.
