摘要： A proposal is made for the photolithographic formation of a patterned resist layer on a substrate without the troubles due to reflection of the exposure light on the substrate surface. Thus, patterning is conducted on a photo-resist laminate comprising (a) a substrate; (b) a specific anti-reflection coating layer formed on one surface of the substrate; and (c) a photoresist layer formed on the anti-reflection coating layer from a specific negative-working chemical-sensitization photoresist composition. The patterning procedure comprises the steps of: (A) exposing, pattern-wise to actinic rays, the photoresist layer of the photoresist laminate; (B) subjecting the photoresist layer to a heat treatment; (C) subjecting the photoresist layer to a development treatment to dissolve away the photoresist layer in the areas unexposed to actinic rays in step (A) so as to expose bare the anti-reflection coating layer in the areas unexposed to the actinic rays leaving a patterned resist layer in the areas exposed to the actinic rays; and (D) removing the pattern-wise exposed anti-reflection coating layer by dry etching with the patterned photoresist layer as a mask.

摘要： The invention proposes an improved method for the pre-treatment of a photoresist layer formed on a substrate surface prior to pattern-wise exposure of the photoresist layer to actinic rays, in which extraneous portions of the resist layer formed by overspreading of the photoresist solution as in the marginal zone of the patterning area and on the peripheral and back surfaces of the substrate, by dissolving away with a cleaning solution. In contrast to the conventional cleaning solutions consisting entirely or mainly of an organic solvent capable of dissolving the photoresist composition, the cleaning solution used in the inventive method is an aqueous alkaline solution containing a water-soluble alkaline compound dissolved in an aqueous medium consisting of water and a limited amount of a water-miscible organic solvent such as monohydric alcohols, alkyleneglycol monoalkyl ethers and aprotic solvents. The cleaning solution may optionally contain an anti-corrosion agent.

摘要： Stock developer solutions for photoresists contain an organic base free from metal ions and at least one compound having a specified weight average molecular weight that is selected from among polyethylene oxide compounds, polypropylene oxide compounds and ethylene oxide/propylene oxide adducts. The stock developer solutions may be diluted to requisite concentrations to prepare developer solutions for photoresists. By adding one or more of the specified compounds to the organic base free from metal ions, one can produce highly compatible stock developer solutions for photoresists that are concentrated, that have high stability in quality and that permit ease in handling and quality control. The stock developer solutions may be diluted to prepare developer solutions that are small in the tendency to foam and effective in defoaming, that assure uniform wetting and that are capable of forming resist patterns faithful to mask patterns.
