Patent ID: 8196296

Claim:
A method for manufacturing a wiring board, comprising: an insulation layer generation member preparation step of preparing an insulation layer generation member having a support film and a semi-cured insulation layer provided on a surface of the support film; an insulation layer generation member affixing step of affixing the insulation layer generation member to a pad such that the pad contacts the semi-cured insulation layer; an insulation layer curing step of curing the semi-cured insulation layer after the insulation layer generation member affixing step; and an opening generation step of exposing the cured insulation layer to a laser by way of the support film, wherein the laser is irradiated onto a top surface of the support film thereby opening an opening in the support film and an opening in the cured insulation layer, the support film preventing exposure of the insulation layer to a portion of the laser corresponding to a low energy region such that a portion of the laser corresponding to a high energy region forms the opening in the cured insulation layer.
