ETCHING METHOD, EVALUATION METHOD FOR METALLOGRAPHIC STRUCTURE INCLUDING EXECUTION OF THE ETCHING METHOD AND ETCHING SOLUTION

摘要

PROBLEM TO BE SOLVED: To enable sufficient etching of the surface of an object even when the angle of the surface of the object to the upward horizontal surface is large and facilitate work in e.g. an etching application step. ! SOLUTION: An etching method includes an etching solution formation step of forming an etching solution 20 by mixing an acetic acid alcohol 21 serving as a metal corrosion liquid with glycerol 22 and an etching solution application step of applying the etching solution 20 to the surface 11 of an object 10. !
