Abstract
In each of a p-channel MOS transistor and an n-channel MOS transistor, a channel direction is set in the <100> direction and a first stressor film accumulating therein a tensile stress is formed in a STI device isolation structure. Further, a second stressor film accumulating therein a tensile stress is formed on a silicon substrate so as to cover the device isolation structure.
