Abstract
The degree of freedom of an abnormality detection target location in a solid-state imaging device in which a plurality of substrates are joined is improved. A semiconductor device includes a connection line and a detection circuit. A plurality of semiconductor substrates are joined in the semiconductor device. Then, in the semiconductor device, the connection line is wired across the plurality of semiconductor substrates. The detection circuit detects the presence or absence of an abnormality in a joint surface of the plurality of semiconductor substrates based on an energization state of the connection line when enable has been set by a predetermined control signal.
