Abstract
The present invention discloses a semiconductor device and a manufacturing method thereof which improves its characteristics even though it is miniaturized. According to one aspect of the present invention, it is provided a semiconductor device comprising a first semiconductor element device including a pair of first diffusion layers formed in the semiconductor substrate with a first gate electrode therebetween, and a first conductor layer formed in the first diffusion layer and having an internal stress in a first direction, and a second semiconductor element device including a pair of second diffusion layers formed in the semiconductor substrate with a second gate electrode therebetween, and a second conductor layer formed in the second diffusion layer, having an internal stress in a second direction opposite to the first direction, and constituted of the same element as that of the first conductor layer.
