Abstract
An insulating film covering the lower surface of an external connection electrode of a semiconductor construct is formed. A mask metal layer in which there is formed an opening having a planar size smaller than that of the external connection electrode is formed on the insulating film. The mask metal layer is used as a mask to apply a laser beam to the insulating film, such that a connection opening reaching the external connection electrode is formed in the insulating film. A wiring line is formed on the insulating film in such a manner as to be connected to the external connection electrode via the connection opening.
