Patent number: 6794112Abstract: The negative resist composition comprises (1) a film-forming polymer which is itself soluble in basic aqueous solutions, and contains a first monomer unit with an alkali-soluble group in the molecule and a second monomer unit with an alcohol structure on the side chain which is capable of reacting with the alkali-soluble group, and (2) a photo acid generator which, when decomposed by absorption of image-forming radiation, is capable of generating an acid that can induce reaction between the alcohol structure of the second monomer unit and the alkali-soluble group of the first monomer unit, or protect the alkali-soluble group of the first monomer unit. The resist composition can form intricate negative resist patterns with practical sensitivity and no swelling.Type: GrantFiled: November 12, 2002Date of Patent: September 21, 2004Assignee: Fujitsu LimitedInventors: Koji Nozaki, Takahisa Namiki, Ei Yano, Junichi Kon, Miwa Kozawa

Patent number: 6764811Abstract: 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.Type: GrantFiled: January 2, 2002Date of Patent: July 20, 2004Assignee: Matsushita Electric Industry Co., Ltd.Inventors: Masayuki Endo, Masaru Sasago

Patent number: 6746827Abstract: A method for structuring a photoresist layer includes the steps of providing a substrate on which a photoresist layer has been applied at least in some areas. The photoresist layer includes a film-forming polymer that contains molecule groups that can be converted into alkali-soluble groups by acid-catalyzed elimination reactions. The polymer further includes a photoacid generator that, on exposure to light from a defined wavelength range, releases an acid. The polymer additionally has a thermobase generator that releases a base when the temperature is raised. The photoresist layer is initially exposed, in some areas, to light from the defined wavelength range. The photoresist layer is then heated to a temperature at which the elimination reaction catalyzed by the photolytically generated acid takes place and the thermobase generator releases a base. Finally, the photoresist layer is developed.Type: GrantFiled: April 29, 2002Date of Patent: June 8, 2004Assignee: Infineon Technologies AGInventors: Ernst-Christian Richter, Michael Sebald

Publication number: 20040067441Abstract: An improved light attenuating compound for use in the production of microdevices is provided. Broadly, the light attenuating compound is non-aromatic and can be directly incorporated (either physically or chemically) into photolithographic compositions such as bottom anti-reflective coatings (BARC) and contact or via hole fill materials. The preferred non-aromatic compounds of the invention are conjugated aliphatic and alicyclic compounds which greatly enhance the plasma etch rate of the composition. Furthermore, the light attenuating compounds are useful for absorbing light at shorter wavelengths. In one embodiment, the inventive compounds can be polymerized so as to serve as both the polymer binder of the composition as well as the light absorbing constituent.Type: ApplicationFiled: October 20, 2003Publication date: April 8, 2004Inventors: Xie Shao, Robert Cox, Shreeram V.
