It is an object to enhance an adhesion strength of a bonding pad in a semiconductor device having a fluorine doped silicon oxide film as an interlayer insulating film. A second interlayer insulating film (4) provided with a bonding pad (6) on an upper surface has a three-layered structure including an F doped silicon oxide film (4a), a TEOS based silicon oxide film (4b) and an SiH4 based silicon oxide film (4c). A dummy pattern (10) having an equal size to that of the bonding pad (6) is provided in a region right under the bonding pad (6), and the F doped silicon oxide film (4a) and the SiH4 based silicon oxide film (4c) are in contact with each other in a region right on the dummy pattern (10). More specifically, an interface of the TEOS based silicon oxide film (4b) and the SiH4 based silicon oxide film (4c) is hardly present in a region right under the bonding pad (6). Consequently, pile-up of fluorine is hardly generated in the region right under the bonding pad (6) so that an adhesion strength of the bonding pad (6) can be enhanced.
