Title: Photosensitive material
Inventor: AOKI NOBUO
IPC: H01L21/027
Filed: 1992-06-30
Abstract: PURPOSE:To provide a resist which satisfies the requirement for high resolution and high sensitivity by adding photosensitive group to Fullerene. CONSTITUTION:Photosensitive groups are added to Fullerene which is a carbon allotrope called as a carbon cluster. Fullerene expressed by molecular formula C60 or C70 is preferably used. Any functional groups which can cause chemical reaction by irradiation of UV rays, for UV rays, X-rays, electron beams or the like can be used as the photosensitive groups. To introduce photosensitive groups to Fullerene, normal chemical reaction is used. For example, Fullerene is stirred in alkyl amine at room temp. for several hours to add alkyl amino to the Fullerene and then the reaction with methacryl chloride is effected at room temp. for several hours. Thus, a photosensitive material having methacrylamide group as photosensitive groups can be synthesized. This photosensitive material has high dry etching resistance and can be used in a thin film state, so that the film has high resolution and high sensitivity.

Abstract: PURPOSE:To give high oxygen permeability and to reduce tendency to protein deposi tion by forming a contact lens made of a copolymer of a monomer contg. a specified methyl or methylsiloxy group and a hydrophilic monomer and a comonomer essentially composed of polyfunctional acrylate or methacrylate. CONSTITUTION:The copolymer is composed of units of at least one kind of the hydrophilic monomers, a comonomer essentially composed of polyfunctional acrylate or methacrylate, and at least one kind of monomers represented by formula I [in which R<1> is H or methyl; l is 0 or 1; m is an integer of 1-3; x<1>, x<2> are each indepen dently methyl, a group of bis(trimethylsiloxy)methylsiloxane] or a group of formula II [p, n are each independently an integer of 1-3; j is an integer of 2-18; and k is an integer of 2-2j-2]. The value of l depends on the content of the hydrophilic units by considering hydrophilicness, and the high value of j increases the content of fluoroalkyl chains and lowers refractive index and increases oxygen permeability. The presence of the bulky siloxanyl groups improves oxygen permeability, and since the combined polyfluoroalkyl groups have high affinity to gases, the presence of them also improves oxygen permeability. Further, the low surface energy of the poly fluoroalkyl groups extremely lowers the tendency of deposition of protein, etc., to the surface of the lens.
