Abstract
On the lower surface of a semiconductor construct having an external connection electrode, there are formed an insulating film having a planar size greater than that of the semiconductor construct, and a metal layer and a mask metal layer having a connection pad portion in which a first opening corresponding to the external connection electrode is formed. A laser beam is applied using the mask metal layer as a mask, and a second opening is thereby formed in a part of the insulating film corresponding to the external connection electrode. Then, a connection conductor is formed to connect a wiring line to the external connection electrode via the second opening of the insulating film.
