Structures for measuring misalignment of patterns
Abstract:
A structure for measuring misalignment of patterns may include a first wiring and a second wiring. The first wiring may include a first lower pattern and a first upper pattern. The first upper pattern may extend in a y-direction, and a first end portion of the first upper pattern that is relatively further toward (proximal to) a negative y-direction may contact the first lower pattern. The second wiring may include a second lower pattern and a second upper pattern. The second upper pattern may extend in the y-direction, a second end portion of the second upper pattern that is relatively further toward (proximal to) a positive y-direction may contact the second lower pattern. The second wiring may be spaced apart from the first wiring along the negative y-direction.
