A semiconductor integrated circuit device in accordance with the present invention is provided with first electrode pads, a first insulation layer and a second insulation layer. The first electrode pad are formed on the circuit formation face side of an IC chip. The first insulation layer is placed on areas other than the upper portions of the first electrode pads.

Here, the wire and the second electrode are formed by filling the opening section of the second insulation layer with particles of a conductive material. Thus, it is possible to provide a semiconductor integrated circuit device to which a fine wire processing technique is applied while maintaining the same functions as conventional devices at low costs, and a manufacturing method for such a device.
