Abstract:
A device structure includes an array of semiconductor devices located in an array region over a substrate, metal lines laterally extending from the device region to a peripheral interconnection region, and interconnect via structures located in the peripheral interconnection region, and contacting a portion of a respective one of the plurality of metal lines. The metal lines include a first metal line and a second metal line each having a serpentine region which contacts a respective interconnect via structure.

Claim (Index 12):
A method of forming a metal contact structure, comprising:\n forming a metal layer on surfaces of interconnect via structures; forming a matrix material layer over the metal layer; patterning the matrix material layer with a matrix pattern to form matrix pattern structures that includes a plurality of shapes, wherein each of the plurality of shapes include a first extension line pattern and a second extension line pattern that laterally extend along a first horizontal direction and laterally offset along a second horizontal direction, and a fishbone pattern that includes parallel stripe portions that laterally extend along the first horizontal direction and spaced apart along the second horizontal direction and further includes an interconnecting portion that intersects each of the parallel stripe patterns and extends along the second horizontal direction and connecting the first extension line pattern and the second extension line pattern; forming sidewall spacers on sidewalls of the matrix pattern structures by conformally depositing and anisotropically etching a spacer material; removing the matrix pattern structures selective to the sidewall spacers; and forming a plurality of metal lines having a serpentine region which contacts a respective interconnect via structure by etching the metal layer using the sidewall spacers as a mask.
