Abstract:
A semiconductor device comprising:a semiconductor substrate having an upper surface on which a circuit element and a plurality of connection pads which are connected to an external device and which include at least one first connection pad and at least one second connection pad are formed; a first insulating film formed on the upper surface of the semiconductor substrate to expose a central portion of each of the connection pads, the first insulating film having the same area as that of the upper surface of the semiconductor substrate; a first columnar electrode which is formed on the first connection pad so as to be electrically connected to the first connection pad and connected to an external device, the first columnar electrode having an upper end surface externally exposed; at least one first conductive layer which is formed on the first insulating layer so as to be electrically connected to the second connection pad; a second insulating film which is formed at least around the first columnar electrode, on the first insulating film and on the first conductive layer, the second insulating film having the same area as that of the surface of the semiconductor substrate; a second conductive layer which is formed on the second insulating film so as to face the first conductive layer; and at least one passive element which is formed to include the first and second conductive layers.
