Abstract:
A semiconductor device comprising:a first semiconductor chip having, on an active surface, a first internal connection electrode and a first lateral-deviation confirming electrode; and a second semiconductor chip connected opposed at an active surface thereof to the active surface of the first semiconductor chip and having, on the active surface thereof, a second internal connection electrode corresponding to the first internal connection electrode and a second lateral-deviation confirming electrode corresponding to the first lateral-deviation confirming electrode; whereby the first lateral-deviation confirming electrode and the second lateral-deviation confirming electrode are arranged on the respective active surfaces of the first and second semiconductor chips in a positional relationship that mutual connection is made when the first internal connection electrode and the second internal connection electrode are connected together in a predetermined relative position in an on-plane direction of the active surface but mutual connection is not made when the first internal connection electrode and the second internal connection electrode deviate by a constant distance or greater in a predetermined lateral-deviation detecting direction on the plane of the active surface within a range to keep mutual connection thereof.
