Cooling device semiconductor device including end curved interconnection lines

Abstract

A semiconductor device may include a substrate including a first logic cell and a second logic cell, which are adjacent to each other in a first direction and shares a cell border, a first metal layer on the substrate, the first metal layer including a power line, which is disposed on the cell border to extend in a second direction crossing the first direction and has a center line parallel to the second direction, and a second metal layer on the first metal layer. The second metal layer may include a first upper interconnection line and a second upper interconnection line, which are provided on each of the first and second logic cells. The first upper interconnection line may extend along a first interconnection track and the first direction. The second upper interconnection line may extend along a second interconnection track and in the first direction.
