Patent ID: 7226806

Claim:
A process for producing an electronic component, comprising the steps of: providing (A) a laminate of a conductive inorganic material later, an insulating layer, and a conductive inorganic material layer, or (B) a laminate of a conductive inorganic material later and an insulating layer; wet etching the conductive inorganic material layer in the laminate thereby patterning the conductive inorganic material layer; laminating a dry film resist onto said laminate in which the conductive inorganic material layer has been patterned; patterning the dry film resist, the dry film resist being developable with an aqueous solution and being able to be separated by the aqueous solution; treating the thus patterned dry film resist with ultraviolet light irradiation and/or heat thereby improving the resistance of the dry film resist to the etchant for the insulating layer; and wet etching the insulating layer through the patterned dry film resist by an aqueous basic solution.
