Abstract:
1. A method of forming a semiconductor structure, the method comprising: bonding a first dielectric layer carried on a first semiconductor layer of a first crystal orientation with a second dielectric layer carried on a second semiconductor layer of a second crystal orientation differing from the first crystal orientation; defining a plurality of openings each having sidewalls extending from a top surface of the first semiconductor layer through the first and second dielectric layers to the second semiconductor layer; applying dielectric regions to the sidewalls of each of the openings; epitaxially growing an island of semiconductor material having the second crystal orientation of the second semiconductor layer to fill each of the openings; forming an insulating layer at a depth that divides the first semiconductor layer into a plurality of device regions between the insulating layer and the top surface and a plurality of body regions between the insulating layer and the first and second dielectric layers such that each of the body regions is aligned with one of the device regions between an adjacent pair of the dielectric regions; forming a shallow trench isolation region extending from the top surface of the first semiconductor layer to the insulating layer; and forming a contact extending through the shallow trench isolation region and the insulating layer to one of the body regions.
