- a chemically amplified resist which is an essential material in common technology for lithography utilizing light or charged particle beams such as electron beams or ion beams, is a resist which is easily influenced by the use environment and is difficult to handle.
- a resist patterned through a developing step is subsequently used for a pattern transfer to a substrate by a dry etching step, and dry-etching resistance of the resist in this process is becoming more important, so that requirements for the prevention of a film thickness loss phenomenon of the resist caused by a charge-up preventing film and for the maintenance of a resist profile are becoming stricter in recent years.
- the liquid components show mutual penetration.
- a mixing layer is formed at the interface between the resist and the antistatic treatment film.
- Such an undesired chemical change at the interface generates a profile called a bowing or a T-top in the resist after patterning.
- a profile called a bowing or a T-top in the resist after patterning.
- the development of such profile detrimentally affects control of variation in the line width and the depth and shape of etching, thus constituting a serious problem in fine patterning.

- Br ⁇ nsted acids present in anionic surfactant and/or amphoteric surfactant together with Br ⁇ nsted acids present in the aqueous solvent-soluble electroconductive polymer, are neutralized by a diamine (divalent) or polyamine (polyvalent) aliphatic basic compound, and thereby crosslinking-like ionic bonds are formed between arbitrary Br ⁇ nsted acid sites of the electroconductive polymer and the anionic surfactant and the basic compound.
- the mobility of the electroconductive polymer and the surfactant can be suppressed to thereby exhibit an effect of preventing film thinning and also to exhibit an unprecededly excellent wettability.

- the amount of the anionic surfactant to be added to the antistatic treatment agent of the present invention is preferably from 0.001 to 1 mass%, based on the entire antistatic treatment agent as 100 mass %. If the blending amount is 0.001 mass % or more, the effect of the invention can be obtained. If the blending amount is 1 % or less, the resist profile such as film thickness is not affected.

- the antistatic treatment agent of the present invention can be regulated to an arbitrary pH value from acidic to alkaline state, by varying an addition amount of an amine used for neutralizing the Br ⁇ nsted acid of the aqueous solvent-soluble electroconductive polymer and the anionic surfactant contained in the solution.
- the number of moles of the basic group contained in the diamine (divalent) or polyamine (polyvalent) aliphatic basic compound preferably is from 0.05 to 50 mol % by molar ratio, based on the number of moles of the Br ⁇ nsted acid group of the aqueous solvent-soluble electroconductive polymer. If the number of moles is less than 0.05, an effect of the present invention cannot be obtained. If it exceeds 50 mol %, it may cause reduction in the conductivity and insolubilization of the aqueous solvent-soluble electroconductive polymer.
