Classification: CPC H | IPC H

Claim 19:
20. A semiconductor device, comprising:
a first seal-ring surrounding a circuit region;
a crack detection ring surrounding the first seal-ring;
a second seal-ring surrounding the first seal-ring and the crack detection ring;
a connection part connecting the first seal-ring and the crack detection ring;
a crack detection structure disposed in the circuit region and electrically connected to the crack detection ring,
an upper interlayer insulating layer formed on the first surface of the upper substrate and surrounding the first seal-ring, the second seal-ring, and the crack detection ring;
a bonding insulating layer on a surface of the upper interlayer insulating layer;
a lower interlayer insulating layer on a surface of the bonding insulating layer; and
a lower substrate on a surface of the lower interlayer insulating layer,
wherein the crack detection structure includes a control unit and an operation unit,
wherein the control unit provides voltage or current to the crack detection ring,
wherein the operation unit detects the voltage or current from the crack detection ring, and
wherein the control unit and the operation unit are disposed on the lower substrate.
