Patent ID: 11573489

Abstract:
An object of the present invention is to provide a solution which contains an organic solvent as a main component (content: equal to or greater than 98% by mass) and has an excellent defect inhibition ability.Another object of the present invention is to provide a solution storage body storing the solution, an actinic ray-sensitive or radiation-sensitive resin composition containing the solution, and a pattern forming method and a manufacturing method of a semiconductor device using the solution.The solution of the present invention is a solution containing at least one kind of organic solvent having a boiling point lower than 200° C. and an organic impurity having a boiling point equal to or higher than 250° C., in which a content of the organic solvent with respect to a total mass of the solution is equal to or greater than 98% by mass, and a content of the organic impurity with respect to the total mass of the solution is equal to or greater than 0.1 mass ppm and less than 100 mass ppm.
