The present invention provides a semiconductor material that has enhanced
electron and hole mobilities that comprises a Si-containing layer having
a <110> crystal orientation and a biaxial compressive strain. The
term "biaxial compressive stress" is used herein to describe the net
stress caused by longitudinal compressive stress and lateral stress that
is induced upon the Si-containing layer during the manufacturing of the
semiconductor material. Other aspect of the present invention relates to
a method of forming the semiconductor material of the present invention.
The method of the present invention includes the steps of providing a
silicon-containing <110> layer; and creating a biaxial strain in
the silicon-containing <110> layer.
