Abstract: PURPOSE:To suppress the damage of the board to be processed so as to exfoliate a resist by applying a far ultraviolet ray to the positive EB resistor to be exfoliated so as to expose the resist, and then developing it in an organic solvent. CONSTITUTION:A far ultraviolet ray 18 is applied to the positive EB resistor to be exfoliated to expose the positive EB resist, and then it is developed in an organic solvent. That is, by applying the far ultraviolet ray 18, the positive EB resist at the irradiated part is exposed, so the part irradiated with an far ultraviolet ray 18 changes to the structure that it dissolves in the organic solvent being developer. Accordingly, when it is developed in the organic solvent, the resist at the exposed part dissolves in the organic solvent, and is removed from on the board 14 to be processed. Hereby, while suppressing the damage of the board 14 to be processed to the minimum, the resist can be removed completely, and also the board to be processed can be maintained in clean condition after removal.

Abstract: PURPOSE:To use the title anisotropic etchant during an IC process, to improve workability and the accuracy of finishing and to form an etching surface in a mirror surface by containing one kind of a specific ammonium hydroxide at specific content. CONSTITUTION:At least one kind of a quaternary ammonium hydroxide shown in (R1R2R3R4N)<+>OH<-> contained within a range from 20wt.% to 50wt.% in the relaxation of content. (where R1-4 represents an arbitrary alkyl group of IC to 10C) A micro-pyramid is generated in an etching surface and irregularities are increased when the concentration of tetraalkyl ammonium hydroxide in an etching solution is brought to 20wt.% or less. When the content is made larger than 50wt.%, the viscosity of the etchant is augmented, a diffusion is delayed and an etching rate is decreased. When a methyl group and an ethyl group are used particularly as a substituent group as an alkyl substituent group, a specular effect is improved. When the number of carbon exceeds ten, molecular weight is increased, and the etching rate is reduced with the delay of the diffusion resulting from the viscosity of the liquid.
