摘要:
A semiconductor device includes a semiconductor substrate having bump electrodes and a sealing film formed thereon, the sealing film having laminated layers. The sealing film interposed between adjacent bump electrodes is prepared by laminating a protective film and each layer of the sealing film on the lower surface of the base film, on the bump electrodes, followed by allowing the bump electrodes to project through the sealing film under pressure and heat. The thickness of the sealing film is smaller than the height of the bump electrode, and thus the bump electrode projects through the sealing film. Particles for lowering the thermal expansion coefficient are dispersed in the sealing film to allow the sealing layers to exhibit a thermal expansion coefficient differing in its thickness direction such that the thermal expansion coefficient in the layer which is close to the semiconductor substrate is close to that of the semiconductor substrate.

In a semiconductor device, re-wiring is provided on a circuit element formation region of a semiconductor substrate. A columnar electrode for connection with a circuit board is provided on the rewiring. A first insulating film is provided over the semiconductor substrate excluding a connection pad, and a ground potential layer connected to a ground potential is provided on an upper surface of the first insulating film. A re-wiring is provided over the ground potential layer with a second insulating film interposed. The ground potential layer serves as a barrier layer for preventing crosstalk between the re-wiring and circuit element formation region. A thin-film circuit element is provided on the second insulating film, and a second ground potential layer is provided as a second barrier layer over the thin-film circuit element with an insulating film interposed. Re-wiring is provided over the second ground potential layer.

A photosensor comprises a photoelectric conversion device region and a connection pad on the lower surface of a semiconductor substrate, and also comprises a wiring line connected to the connection pad via insulating film under the semiconductor substrate, and a columnar electrode as an external connection electrode connected to the wiring line. As a result, as compared with the case where the photoelectric conversion device region and the connection pad connected to the photoelectric conversion device region are formed on the upper surface of the semiconductor substrate, a piercing electrode for connecting the connection pad and the wiring line does not have to be formed in the semiconductor substrate. Thus, the number of steps can be smaller, and a fabrication process can be less restricted.
