Abstract
The present invention provides novel structures of MOS field effect transistor which operate with high speed and low power consumption. This has been achieved through providing epitaxial growth layers on a substrate of high impurity doping concentration in which the thickness of epitaxial growth layers is controlled with a degree of accuracy on the order of a single atom layer.
