Abstract
A semiconductor device includes metal layers, first dummy conductive cells, and groups of second dummy conductive cells. The metal layers include empty areas and are grouped into pairs of neighboring metal layers. The first dummy conductive cells are each formed in each of the empty areas in each of the pairs of neighboring metal layers that is overlapped by another empty area or a line in the same pair of neighboring metal layers. Each group of the second dummy conductive cells is formed in each of the empty areas in each of the pairs of neighboring metal layers that is overlapped by a signal line in the same pair of neighboring metal layer.
