Abstract

A semiconductor device including a plurality of cells having an antenna protection element and a cell other than the antenna protection element; and a first dummy pattern and a second dummy pattern arranged in a layer above the plurality of cells. Further, the first dummy pattern overlaps with the antenna protection element, the second dummy pattern overlaps with the cell other than the antenna protection element, and a first layout rule of the first dummy pattern is different from a second layout rule of the second dummy pattern.

Dependent claims

A semiconductor device, comprising:

a plurality of cells including a first cell which is an antenna protection element and a second cell which is a cell other than the antenna protection element;
and
at least one dummy pattern arranged in a same layer above the plurality of cells,
wherein the at least one dummy pattern overlaps with both the first cell and the second cell,
an area where the first cell and the at least one dummy pattern overlap with each other is smaller than an area where the second cell and the at least one dummy pattern overlap with each other.
