Abstract
Detecting defective joining parts between semiconductor substrates is disclosed. In one example, a semiconductor device includes a first semiconductor substrate and a second semiconductor substrate stacked and joined together, a connection line having a plurality of pairs of connection pads connected to each other with a joint surface between the substrates interposed therebetween, the connection line being routed from one of the first and second semiconductor substrates to the other alternately a plurality of times via the pairs of the connection pads, and a detection circuit configured to detect whether or not the connection line has failed.
