Abstract:
A process for producing an electronic component, comprising the steps of: wet etching a laminate of conductive inorganic material layerâ€”insulating layerâ€”conductive inorganic material layer or a laminate of conductive inorganic material layerâ€”insulating layer to pattern the conductive inorganic material layer; and then performing wet etching to pattern the insulating layer, whereinthe insulating layer in the laminate is wet etchable and has a single-layer structure or a laminate structure of two or more insulation unit layers, after the patterning of the conductive inorganic material layer in the laminate, the patterning of the insulating layer by wet etching is carried out in a continuous form in a continuous feed, continuous production line using a dry film resist, and in patterning the insulating layer using the dry film resist, the dry film resist is laminated by roll pressing onto the laminate under a reduced pressure of not more than 80 KPa.
