A semiconductor device has a structure that is capable of reducing warping of a semiconductor wafer when the semiconductor device is manufactured. The semiconductor device is manufactured by a method including the steps for forming an interlayer dielectric film having an internal compression stress and an interlayer dielectric film having an internal tensile stress. As a result, when semiconductor devices are manufactured, the tensile stress and the compression stress act on the semiconductor wafer. As a consequence, the overall stress that acts on the semiconductor wafer are reduced to a small level or to zero, and thus warping of the semiconductor wafer is reduced or eliminated when semiconductor devices are manufactured.
