Abstract: 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.

Abstract: In the claimed mixed-crystal-orientation channel FET, source/drain regions above the bonded interface 360 have the orientation of the upper semiconductor 350 and source/drain regions below the bonded interface 360 have the orientation of the lower semiconductor 370, so that each part of the source/drain has the same crystal orientation as the semiconductor material laterally adjacent to it. Optional source/drain extensions 392 are disposed entirely in the upper semiconductor layer 350. Optionally, the bonded interface 360 is situated towards the bottom of source/drain regions 380, leaving source/drains 380 mostly in upper semiconductor layer 350.

Abstract: This invention teaches methods of combining ion implantation steps with in situ or ex situ heat treatments to avoid and/or minimize implant-induced amorphization (a potential problem for source/drain (SfD) regions in FETs in ultrathin silicon on insulator layers) and implant-induced plastic relaxation of strained S/D regions (a potential problem for strained channel FETs in which the channel strain is provided by embedded S/D regions lattice mismatched with an underlying substrate layer). In a first embodiment, ion implantation is combined with in situ heat treatment by performing the ion implantation at elevated temperature. In a second embodiment, ion implantation is combined withex situ heat treatments in a "divided-dose-anneal-in-between" (DDAB) scheme that avoids the need for tooling capable of performing hot implants.
