There are included a semiconductor substrate provided with a desirable
element region, an electrode pad formed to come in contact with a surface
of the semiconductor substrate or a wiring layer provided on the surface
of the semiconductor substrate, a bump formed on a surface of the
electrode pad through an intermediate layer, and a resin insulating film
formed in at least a peripheral portion of the bump to cover an interface
of the bump and the intermediate layer which is exposed to a side surface
of the bump.
