Abstract
A plurality of wiring layers are laminated on an LSI chip. Each wiring layer includes an electrode to which is applied a mechanical pressure, a first insulating film formed in a region where it is necessary to have a high mechanical strength and having the electrode formed therein, a second insulating film formed in the same layer as the layer of the first insulating film and formed in a region where a mechanical strength higher than that of the first insulating layer is not required, and a wiring layer formed on the surface of the second insulating film.
