Abstract:
Some embodiments of the present disclosure provide a method for fabricating a semiconductor structure. The method includes forming a recess in a substrate and forming an epitaxy region, comprising a multilayer structure with a substance having a first lattice constant larger than a second lattice constant of the substrate. Forming the epitaxy region further includes forming a first layer in proximity to an interface between the epitaxy region and the substrate with an average concentration of the substance from about 20 to about 32 percent by an in situ growth, and forming a second layer over the first layer, a bottom portion of the second layer having a concentration of the substance from about 27 percent to about 37 percent by an in situ growth operation.

Claim (Index 13):
A method for fabricating a semiconductor structure, comprising:\n forming a recess in a substrate; and forming an epitaxy region comprising a substance having a first lattice constant larger than a second lattice constant of the substrate, comprising: forming a first layer on a bottom and a sidewall of the recess, the first layer having an average concentration of the substance from about 20 to about 32 percent by an in situ growth; and forming a second layer over the first layer, a bottom portion of the second layer having a concentration of the substance from about 27 percent to about 37 percent by an in situ growth operation.
