Assignee: SK HYNIX INC.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 1:
2. The semiconductor device of claim 1,
wherein the crack detection ring includes:
a crack detection doped region formed in the upper substrate;
a multilayer of crack detection pad patterns formed on a first surface of the upper substrate; and
a multilayer of crack detection via patterns electrically connecting the crack detection doped region and the crack detection pad patterns,
wherein the crack detection doped region horizontally and electrically connects two crack detection via patterns adjacent to each other among the crack detection via patterns, and
wherein one of the crack detection pad patterns, which is spaced apart farthest from the upper substrate, horizontally and electrically connects two crack detection via patterns adjacent to each other among the crack detection via patterns.
