Abstract:
1. A semiconductor device comprising: a semiconductor substrate; a low dielectric constant film and wiring laminated structure section having a laminated structure including a low-dielectric film having a dielectric constant of 3.0 or less and a wiring, which is provided on one surface of the semiconductor substrate excluding a periphery thereof; an insulating film provided on the low dielectric constant film and wiring laminated structure section; an electrode connection pad section provided on the insulating film; an external connection bump electrode provided on the electrode connection pad section; a sealing film made of organic resin provided on the insulating film around a periphery of the external connection bump electrode, a side surface of the insulating film, and a side surface of the low dielectric constant film and wiring laminated structure section; a side-section protective film made of organic resin provided on a side surface of the sealing film and at least an upper section of a side surface of the semiconductor substrate; and a lower-layer protective film made of organic resin provided on at least a bottom surface of the semiconductor substrate.
