摘要:
A resist film is formed from a chemically amplified resist material containing a base polymer including at least one ester out of acrylate and methacrylate and an acid generator that generates an acid when irradiated with light. The resist film is selectively irradiated for pattern exposure with extreme UV of a wavelength of a 1 nm through 30 nm band, and is developed after the pattern exposure, so as to form a resist pattern from an unexposed portion of the resist film. The resist pattern is then annealed, so as to smooth roughness having been caused on the resist pattern.

摘要:
A resist film is formed from a chemically amplified resist material including a base polymer having a lactone group and having neither a hydroxyl group nor a carboxylic group as an adhesion group bonded to a polymer side chain; and an acid generator for generating an acid through irradiation with light. The resist film is irradiated with extreme UV of a wavelength of a 1 nm through 30 nm band for pattern exposure. The resist film is developed after the pattern exposure, so as to form a resist pattern from an unexposed portion of the resist film.
摘要:
A resist film is formed on a semiconductor substrate by using a chemical amplification resist which generates an acid in response to the radiation of KrF excimer laser light and which reacts with the acid. If the resist film is irradiated with the KrF excimer laser light through a mask, the acid 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 acid. 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 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.

More particularly, in the exposure apparatus using an excimer laser, the beam splitter, mirror and lens for correction for chromatic aberration are combined in the alignment optical system. Furthermore, a mirror is disposed at the opposite side of the image pickup camera of the alignment key by way of the beam splitter.
摘要:
After forming a lower layer film, an intermediate layer film and a first resist film on a substrate, a first resist pattern is formed by performing first exposure. Then, after a first intermediate layer pattern is formed by transferring the first resist pattern onto the intermediate layer film, a second resist film is formed thereon, and a second resist pattern is formed by performing second exposure. Thereafter, a second intermediate layer pattern is formed by transferring the second resist pattern onto the intermediate layer film. After removing the second resist film, the lower layer film is etched by using the second intermediate layer pattern as a mask, so as to form a lower layer pattern.
摘要:
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.
