| 摘要 |
The present invention discloses a semiconductor device having a pad structure for preventing a stress of a silicon nitride film. The semiconductor device includes a semiconductor substrate, a lower structure formed on the semiconductor substrate, a first insulation film formed on the lower structure, a first metal layer coupled to the lower structure through a first metal contact in the first insulation film, a second metal layer formed on the first metal layer, and a plurality of dummy gates having a concentric square structure formed at the lower portion of the pad region on the second metal layer.
