    摘要: Three-dimensional (3D) integration schemes of fabricating a 3D integrated circuit in which the pFETs are located on an optimal crystallographic surface for that device and the nFETs are located on a optimal crystallographic surface for that type of device are provided. In accordance with a first 3D integration scheme of the present invention, first semiconductor devices are pre-built on a semiconductor surface of a first silicon-on-insulator (SOI) substrate and second semiconductor devices are pre-built on a semiconductor surface of a second SOI substrate. After pre-building those two structures, the structure are bonded together and interconnect through wafer-via through vias. In a second 3D integration scheme, a blanket silicon-on-insulator (SOI) substrate having a first SOI layer of a first crystallographic orientation is bonded to a surface of a pre-fabricating wafer having second semiconductor devices on a second SOI layer that has a different crystallographic orientation than the first SOI layer; and forming first semiconductor device on the first SOI layer.

    摘要: A structure and method of fabrication for PFET devices in a compressively strained Ge layer is disclosed. The fabrication method of such devices is compatible with standard CMOS technology and it is fully scalable. The processing includes selective epitaxial depositions of an over 50% Ge content buffer layer, a pure Ge layer, and a SiGe top layer. Fabricated buried channel PMOS devices hosted in the compressively strained Ge layer show superior device characteristics relative to similar Si devices.

    摘要: The present invention provides integrated semiconductor devices that are formed upon an SOI substrate having different crystal orientations that provide optimal performance for a specific device. Specifically, an integrated semiconductor structure including at least an SOI substrate having a top semiconductor layer of a first crystallographic orientation and a semiconductor material of a second crystallographic orientation, wherein the semiconductor material is substantially coplanar and of substantially the same thickness as that of the top semiconductor layer and the first crystallographic orientation is different from the second crystallographic orientation is provided. The SOI substrate is formed by wafer bonding, ion implantation and annealing.

    摘要: A double-gate transistor has front (upper) and back gates aligned laterally by a process of forming symmetric sidewalls in proximity to the front gate and then oxidizing the back gate electrode at a temperature of at least 1000 degrees for a time sufficient to relieve stress in the structure, the oxide penetrating from the side of the transistor body to thicken the back gate oxide on the outer edges, leaving an effective thickness of gate oxide at the center, aligned with the front gate electrode. Optionally, an angled implant from the sides of an oxide enhancing species encourages relatively thicker oxide in the outer implanted areas and an oxide-retarding implant across the transistor body retards oxidation in the vertical direction, thereby permitting increase of the lateral extent of the oxidation.

    摘要: An integrated semiconductor structure containing at least one device formed upon a first crystallographic surface that is optimal for that device, while another device is formed upon a second different crystallographic surface that is optimal for the other device is provided. The method of forming the integrated structure includes providing a bonded substrate including at least a first semiconductor layer of a first crystallographic orientation and a second semiconductor layer of a second different crystallographic orientation. A portion of the bonded substrate is protected to define a first device area, while another portion of the bonded substrate is unprotected. The unprotected portion of the bonded substrate is then etched to expose a surface of the second semiconductor layer and a semiconductor material is regrown on the exposed surface. Following planarization, a first semiconductor device is formed in the first device region and a second semiconductor device is formed on the regrown material.
