Abstract

A method of manufacturing a semiconductor device includes (a) forming a first resin layer on a semiconductor substrate including an electrode pad and a passivation film, (b) curing the first resin layer, (c) forming a second resin layer which slopes more gently than the cured first resin layer on at least a lower portion of the first resin layer, (d) curing the second resin layer to form a resin protrusion including the first and second resin layers, and (e) forming a conductive layer which is electrically connected with the electrode pad and passes over the resin protrusion.
