摘要： The present invention provides a semiconductor structure in which different types of devices are located upon a specific crystal orientation of a hybrid substrate that enhances the performance of each type of device. In the semiconductor structure of the present invention, a dual trench isolation scheme is employed whereby a first trench isolation region of a first depth isolates devices of different polarity from each other, while second trench isolation regions of a second depth, which is shallower than the first depth, are used to isolate devices of the same polarity from each other. The present invention further provides a dual trench semiconductor structure in which pFETs are located on a (110) crystallographic plane, while nFETs are located on a (100) crystallographic plane. In accordance with the present invention, the devices of different polarity, i.e., nFETs and pFETs, are bulk-like devices.

摘要： The present invention provides an integrated semiconductor circuit containing a planar single gated FET and a FinFET located on the same SOI substrate. Specifically, the integrated semiconductor circuit includes a FinFET and a planar single gated FET located atop a buried insulating layer of an silicon-on-insulator substrate, the planar single gated FET is located on a surface of a patterned top semiconductor layer of the silicon-on-insulator substrate and the FinFET has a vertical channel that is perpendicular to the planar single gated FET. A method of forming a method such an integrated circuit is also provided. In the method, resist imaging and a patterned hard mask are used in trimming the width of the FinFET active device region and subsequent resist imaging and etching are used in thinning the thickness of the FET device area. The trimmed active FinFET device region is formed such that it lies perpendicular to the thinned planar single gated FET device region.

摘要： Hybrid orientation substrates allow the fabrication of complementary metal oxide semiconductor (CMOS) circuits in which the n-type field effect transistors (nFETs) are disposed in a semiconductor orientation which is optimal for electron mobility and the p-type field effect transistors (pFETs) are disposed in a semiconductor orientation which is optimal for hole mobility. This invention discloses that the performance advantages of FETs formed entirely in the optimal semiconductor orientation may be achieved by only requiring that the device's channel be disposed in a semiconductor with the optimal orientation. A variety of new FET structures are described, all with the characteristic that at least some part of the FET's channel has a different orientation than at least some part of the FET's source and/or drain. Hybrid substrates into which these new FETs might be incorporated are described along with their methods of making.
