    摘要: A resist mask having a satisfactory resolution effect may be obtained even in the case of use of exposure light having a wavelength of 200 nm or more. An opaque pattern 2a comprising an organic layer for transferring a pattern is constituted by a multi-layer formed by a photo-absorptive organic layer 3a having an light shielding effect or a light attenuating effect even relative to exposure light having a wavelength of 200 nm or more, and a resist layer 4a for chiefly patterning this.

    摘要: Disclosed are methods for forming a resist pattern which solve a problem caused by halation and interference phenomena due to reflected light from the substrate. A first method forms between the substrate and resist film an anti-reflective film whose photoabsorbance of the exposure light is greater on the substrate surface side than on the resist surface side. A second method forms between the substrate and resist film a two-layer anti-reflective film made up of an upper interference film for the exposure light and a lower film having higher exposure light absorbance than the upper film and functions as a light shielding film. A third method forms between the substrate and resist film a two-layer anti-reflective film consisting of a lower film that reflects exposure light and an upper film that is an interference film for the exposure light.

    摘要: Disclosed are methods for forming a resist pattern which solve a problem (dimensional precision degradation) caused by halation and interference phenomena due to reflected light from the substrate, and which are fine and have high precision even with substrates having high reflectivity or substrates having a transparent film or substrates with an uneven surface. A first method forms between the substrate and resist film an anti-reflective film whose photoabsorbance of the exposure light is greater on the substrate surface side than on the resist surface side. A second method forms between the substrate and resist film a two-layer anti-reflective film made up of an upper-layer film which is an interference film for the exposure light and a lower-layer film which has higher exposure light absorbance than the upper-layer film and functions as a light shielding film. A third method forms between the substrate and resist film a two-layer anti-reflective film consisting of a lower-layer film that reflects the exposure light and an upper-layer film that is an interference film for the exposure light. A very high anti-reflection effect can be obtained without aspect ratio problems during the process of forming the anti-reflective film and without being influenced by the kind of substrate including those having a transparent film. With these methods, it is possible to form a fine and highly precise resist pattern. These methods can be used to form patterned resist films to etch object films, e.g., in forming microcircuits and/or gates (and word lines) of semiconductor devices.

    摘要: An inflatable seatbelt system designed so that the thickness of the webbing, when maintained in a strap-like configuration, is minimized, and it is possible to eliminate the webbing folding process and to reduce the amount of base fabric used and yet possible to reliably inflate the webbing when an emergency situation occurs. A shoulder belt (2) is formed from a tubular webbing (17), a tube (16) inserted in the webbing (17), and a cover (15) covering the webbing (17). The tube (16) is made of an elastic material which can be formed relatively thin and which has heat resistance and relatively high strength, e.g., urethane rubber or silicone rubber. The cover (15) is made of a resin material, e.g., polyester. The webbing (17) is made of a knitted fabric formed into a tubular configuration by weft knitting. By the use of the knitted fabric, the webbing (17) is stretchable to a large extent in the lateral direction but does not practically stretch in the longitudinal direction.

    摘要: A color picture tube device equipped with a static convergence adjuster for outer electron beams. The magnetic lines of force of the quadrupole field produced by the adjuster have substantially straight vertical portions. The device is capable of suppressing broadening of the vertical diameters of the spots of the outer beams. Deterioration in the resolution concomitant with adjustment of the convergence of the outer beams can be suppressed.
