    摘要: A pattern forming method, comprising the steps of providing a resist film on a substrate; providing a photosensitive film containing a photosensitive diazonium salt on the resist film; and then subjecting the resultant composite to pattern exposure by use of a light to which both of the resist film and the photosensitive diazonium salt are sensitive, can employ a composition for pattern formation which comprises a photosensitive diazonium salt, a resin binder and a solvent. By this method, a minute pattern of 1 .mu.m or less can be formed, utilizing effectively the UV-ray exposure technique of the prior art, with good dimensional precision and stability.

    摘要: Disclosed are a safe slurry photosensitive composition superior in image formation capabilities such as resolution and sensitivity and containing no harmful compound, and a safe water-soluble photosensitive composition capable of being dissolved in water without using any organic solvent while maintaining a sufficient sensitivity as a resist and containing no harmful substance. The slurry photosensitive composition contains a compound which generates an acid when irradiated with light or ionizing radiation, at least one type of a resin with acid-crosslinkability or acid-decomposability, and a powder. Various devices can be manufactured by forming a layer of this photosensitive composition on a substrate, exposing the layer to light in accordance with a desired pattern, and heating the layer. The water-soluble photosensitive composition contains a compound which generates an acid when irradiated with light or ionizing radiation, and an acetal resin. This water-soluble photosensitive composition is coated on a substrate and irradiated with light or ionizing radiation in accordance with a desired pattern. The resultant substrate is chemically amplified by heating and developed with water. This makes it possible to safely form a pattern without using any ventilator.

    摘要: In a reticle, a semi-transparent film pattern in place of a light blocking film pattern is used as a mask pattern having a size within a certain range, whereby an exposure system can be improved in resolution limit and faithful pattern transfer can be realized with a constant light quantity. A reticle may be of a stacked layer structure which comprises a shift film for providing a different optical path to exposure light, a mask substrate formed on the top or bottom of the shift film, and a transmissivity ratio adjustment layer having a predetermined transmissivity ratio to the exposure light. The material of a phase shifter may be adjusted in amplitude transmissivity ratio so that a shifter width for effectively improving a contrast can be made large and an accuracy necessary for a shifter width can be loosened. The mask pattern may include a semi-transparent film pattern which is made of silicon, a silicon compound, a mixture containing silicon, germanium, a germanium compound or a mixture containing germanium to provide a different optical path from that of the transparent part with respect to lithographic light. A silicon compound, a mixture containing silicon, germanium, a germanium compound or a mixture containing germanium is controlled in its composition ratio to form a semi-transparent film pattern on a transparent substrate.

    摘要: An exposure mask for lithography, a method of manufacturing the same, and an exposure method using the same are disclosed. A light-transmitting opening of the exposure mask has a main light-transmitting region located in the middle of the opening and having a first optical path length, and phase shift regions adjacent to a light-shielding layer and having a second optical path length, different from the first optical path length. Light transmitted through each phase shift region interferes with light transmitted through the main light-transmitting region at the edges of the light-transmitting opening, thus enabling a sharp photo-intensity distribution of total transmitted light to be obtained. As a result, the resolution of the exposure mask is improved.
