Abstract:
An eFuse structure of a semiconductor device may include a first metal formed at a first level on a substrate, a second metal formed at a second level between the first level and the substrate, a third metal formed at a third level between the second level and the substrate, a first via connecting the first metal to the second metal, and a second via connecting the second metal to the third metal. The first metal may include a first portion extending in a first direction, a second portion extending in the first direction and being adjacent to the first portion, and a third portion connecting the first portion to the second portion. A first distance between the first portion and the second portion may be greater than a width of the second portion in a second direction perpendicular to the first direction.

Claim (Index 1):
A semiconductor device, comprising:\n a substrate including a first region and a second region; an eFuse structure formed in the first region; and an interconnect structure formed in the second region, wherein: the eFuse structure includes a first metal pattern formed at a first vertical level on the substrate, a second metal pattern formed at a second vertical level between the first vertical level and the substrate, a third metal pattern formed at a third vertical level between the second vertical level and the substrate, a first via physically connecting the first metal pattern to the second metal pattern, and a second via physically connecting the second metal pattern to the third metal pattern, the first metal pattern includes a first bent portion in a U shape, and a first auxiliary pattern extending in a first direction and being adjacent to and electrically isolated from the first bent portion, the first bent portion includes a first portion which extends in the first direction and is electrically connected to the first via, and a second portion extending in the first direction and being adjacent to the first portion, the second portion is disposed between the first portion and the first auxiliary pattern, and a first distance between the first portion and the second portion spaced apart from the first portion is greater than a width of the second portion in a second direction perpendicular to the first direction.
