Abstract: A co-polymer of benzophenone and bisphenol A has been shown to have DUV absorption properties. Therefore, the co-polymer has particular utility as an antireflective coating in microlithography applications. Incorporating anthracene into the co-polymer backbone enhances absorption at 248 nm. The endcapper used for the co-polymer can vary widely depending on the needs of the user and can be selected to promote adhesion, stability, and absorption of different wavelengths.

Abstract: A composition and methods for the use and manufacture thereof are provided for a polymeric dye. The composition comprises one or more aminoaromatic chromophores in conjunction with polymers having an anhydride group or the reaction products thereof. The composition is particularly useful as an underlaying antireflective coating with microlithographic photoresists for the absorbtion of near or deep ultraviolet radiation.

Abstract: Resists for use in photon, electron beam and x-ray exposure devices comprise a polymeric or molecular composition the solubility of which is dependent upon the presence of acid removable protecting groups and a sulfonic acid precursor which generates a strong acid upon exposure to such radiation. The preferred sulfonic acid precursors are triflate salts of imides.

Abstract: Production of an image on a high-resolution radiation sensitive positive resist material, by comprises (1) applying a film of a poly-(alpha-lower-alkenyl ketone) on a substrate (2) irradiating in a pre-determined pattern, and (3) treating the film with a solvent for the breakdown product formed in the irradiated areas. Used in mfr. of integrated printed circuits, printing plates etc. Post hardening of the photo-resist image is not required. The image has a high resolution, below the film thickness e.g. 0.5 um lines with the same separation can be obtained in 1 um films.

Abstract: 1515330 Electron sensitive polymers INTERNATIONAL BUSINESS MACHINES CORP 5 Dec 1975 [29 Jan 1975] 49960/75 Heading G2C Positive resist masks are formed by exposing a supported film of a non-crosslinked polymeric material to electron beam radiation in a predetermined pattern so as to degrade the polymeric material in the exposed areas, and removing the degraded products in the exposed areas. The polymeric material used is selected from (1) polyalkyl methacrylates and copolymers of alkyl methacrylates with halogen - or cyano - containing monomers and (2) post halogenated derivatives of the polymers in (1). The coated polymers may be baked prior to exposure and also after development.

Abstract: 1500403 Sensitized olefin-sulphone polymers INTERNATIONAL BUSINESS MACHINES CORP 21 May 1975 [26 Sept 1974] 21838/75 Addition to 1421805 Heading G2C A radiation sensitive positive resist comprises an olefin-sulphone polymer sensitized by a charge transfer agent or a free radical source. The polymer is preferably poly (hexene-1-sulphone) and sensitizers include azulene, 2, 4, 7-trinitrofluorenone, fluorene, diphenylamine, p-nitroaniline, CCl4, CBr4, Cl4, phenyl disulphide, azobenzene, and poly(alpha-chloromethylacrylate). The resist is degraded on exposure to U.V., visible light, x-rays, gamma radiation and low energy electron beams of from 10 to 30 KeV. The exposed areas of the polymer are removed using a solvent such as 1,4- dichlorobutane.
