Abstract:
An object of the present invention is to provide a treatment liquid for manufacturing a semiconductor with which the deterioration of lithographic performance or the occurrence of defects is suppressed such that a fine resist pattern or a fine semiconductor element can be manufactured.A treatment liquid for manufacturing a semiconductor according to an embodiment of the present invention includes: one compound (A) that satisfies the following requirement (a);one compound (B) or two or more compounds (B) that satisfy the following requirement (b); and one inorganic matter (C) or two or more inorganic matters (C) having any element selected from the group consisting of Al, B, S, N, and K. Here, a total content of the compound (B) in the treatment liquid is 10−10 to 0.1 mass %, and a ratio P of the inorganic matter (C) to the compound (B) represented by the following Expression I is 103 to 10−6.Requirement (a): a compound that is selected from the group consisting of an alcohol compound, a ketone compound, and an ester compound and of which a content in the treatment liquid is 90.0 to 99.9999999 mass %Requirement (b): a compound that is selected from the group consisting of an alcohol compound having 6 or more carbon atoms, a ketone compound, an ester compound, an ether compound, and an aldehyde compound and of which a content in the treatment liquid is 10−11 to 0.1 mass % P=[Total Mass of Inorganic Matter (C)]/[Total Mass of Compound (B)]   Expression I.
