Abstract
In order to provide a semiconductor device having a field effect transistor with a low power consumption and a high speed by use of the combination of Si and an element such as Ge, C or the like of the same group as Si, a strain is applied by a strain applying semiconductor layerto a channel forming layer I having a channel of the field effect transistor formed therein so that the mobility of carriers in the channel is made larger than the mobility of carriers in that material of the channel forming layer which is unstrained.
