Summary:PURPOSE:To control the developing rate during development and to obtain a positive fine polyimide pattern with likelihood by preparing an alkali soln. containing amino alcohols and other alkali. CONSTITUTION:This developer is an alkali soln. containing 0.5-30wt.% aminoalcohols and other alkali except for aminoalcohols. The aminoalcohols in the developer are pereferably, monoethanolamine, diethanolamine, and isopropanolamine. The alkali except for aminoalchols is preferably tetramethylammonium hydroxide soln. tetraethylammonium hydroxide soln., choline soln., and these alkalis are used in a single or mixed form. Further, a potassium chloride soln., lithium chloride soln. etc., may be used as a controlling agent. This developer may contain an additive component as far as the effect is not decreased.
