Abstract:
A semiconductor device comprising:a semiconductor substrate having a circuit element formation region in which an integrated circuit is formed and a plurality of connection pads, said plurality of connection pads including: (i) at least one first connection pad connected to a barrier layer which is provided on said circuit element formation region, through a first insulating film interposed therebetween and connected to a ground potential, said barrier layer comprising a first conductor layer which covers the circuit element formation region and which is electrically connected to at least one first straight-shaped columnar electrode which is coupled to an outer circuit; and (ii) at least one second connection pad electrically connected to a second conductor layer on said barrier layer, through a second insulating film interposed therebetween, said second conductor layer being connected to at least one second straight-shaped columnar electrode which is coupled to an outer circuit.
