Patent ID: 7223640

Claim:
A method for manufacturing a semiconductor component, comprising: providing a Semiconductor-on-Insulator (SOI) substrate having a major surface, the SOI substrate comprising a first layer of semiconductor material, a layer of dielectric material disposed on the first layer of semiconductor material, and a second layer of semiconductor material disposed on the layer of dielectric material; forming first and second trenches in the SOI substrate, the first and second trenches laterally spaced apart horn each other and extending from the major surface into the first layer of semiconductor material; forming first and second epitaxial semiconductor materials in the first and second trenches, respectively, wherein a portion of the first epitaxial semiconductor material in the first trench contacts the first layer of semiconductor material and has a first dopant concentration and a portion of the first epitaxial semiconductor material in the first trench that is spaced apart from the first layer of semiconductor material has a second dopant concentration and wherein a portion of the second epitaxial semiconductor material in the second trench contacts the first layer of semiconductor material and has a first dopant concentration and a portion of the second epitaxial semiconductor material that is spaced apart from the first layer of semiconductor material has a second dopant concentration; forming a first semiconductor device from the portion of the first epitaxial semiconductor material in the first trench; and forming a second semiconductor device from a portion of the second layer of semiconductor material.
