Abstract:
1. A method of forming an integrated semiconductor structure comprising: providing a hybrid substrate comprising a first semiconducting layer of a first crystallographic orientation, a buried insulating layer located on a surface of the first semiconducting layer and a second semiconducting layer of a second crystallographic orientation which is different from the first crystallographic orientation located on said buried insulating layer; forming a first opening that exposes a surface of the first semiconducting layer; forming a second opening in said hybrid substrate that exposes a surface of the buried insulating layer after forming said first opening, wherein said second opening defines a second area, that is located next to a first area, wherein said second opening has a greater area than an entirety of said first opening and includes all areas of said entirety of said first opening; growing a semiconductor material having the first crystallographic orientation on said first semiconducting layer in said first opening by epitaxy; planarizing the hybrid substrate containing the semiconductor material so that an upper surface of the second semiconducting layer is substantially coplanar with an upper surface of the semiconductor material; and forming at least one first semiconductor device in said first area, while forming at least one second semiconductor device on said semiconductor material in said second area.
