A semiconductor device includes an electrode pad and a protective insulating film having an opening to expose the electrode pad. The semiconductor device further includes a bump (resin core bump) that includes a bump core (resin core) formed on the protective insulating film and a conductive layer formed on the bump core. The semiconductor device further includes an interconnect that connects the conductive layer and the electrode pad. The bump core is in the form of a laminate of plural resin layers (for example, first and second resin layers) that have different elastic modulus. |
