Patent attributes
An integrated circuit includes at least one cell. The at least one cell includes a cell region defined by a cell boundary; a power line structure extending in a first direction parallel to and along the cell boundary and including a first power line extending in the first direction along the cell boundary, a plurality of metal islands spaced apart from one another over the first power line in the first direction, and a second power line extending in the first direction over the plurality of metal islands; and a signal line structure disposed in the cell region at the same level as the first power line and the plurality of metal islands. Separation distances between each of the plurality of metal islands and a part of the signal line structure at the same level as the plurality of metal islands are equal to or greater than a critical separation distance.
