Abstract:
An etching liquid composition that contains (A) 0.1 to 15 mass % of hydrogen peroxide, (B) 0.01 to 1 mass % of a fluoride ion source, (C) an organic sulfonic acid compound represented by general formula (I) described in the specification or a salt thereof in an amount of 0.1 to 20 mass % in terms of organic sulfonic acid, (D) 0.01 to 5 mass % of at least one type of compound selected from among azole-based compounds and compounds having a structure that has a 6-membered heterocycle including at least one nitrogen atom and three double bonds, and (E) water; and an etching method that includes using the etching liquid composition are provided.

Claim (Index 10):
An etching method, comprising: using the etching liquid composition of  claim 2  to etch a titanium-based layer and a copper-based layer of a material to be etched in one step, which is a laminate that is disposed on a base material and includes at least one titanium-based layer and at least one copper-based layer; and thereafter using the etching liquid composition again to etch another material to be etched.
