    摘要: A device and method for inducing stress in a semiconductor layer includes providing a substrate having a dielectric layer formed between a first semiconductor layer and a second semiconductor layer. A removable buried layer is provided on or in the second semiconductor layer. A gate structure with side spacers is formed on the first semiconductor layer. Recesses are formed down to the removable buried layer in areas for source and drain regions. The removable buried layer is etched away to form an undercut below the dielectric layer below the gate structure. A stressor layer is formed in the undercut, and source and drain regions are formed.

    摘要: Methods for fabricating FET device structures are disclosed. The methods include receiving a fin of a Si based material, and converting a region of the fin into an oxide element. The oxide element exerts pressure onto the fin where a Fin-FET device is fabricated. The exerted pressure induces compressive stress in the device channel of the Fin-FET device. The methods also include receiving a rectangular member of a Si based material and converting a region of the member into an oxide element. The methods further include patterning the member that N fins are formed in parallel, while being abutted by the oxide element, which exerts pressure onto the N fins. Fin-FET devices are fabricated in the compressed fins, which results in compressively stressed device channels. FET devices structures are also disclosed. An FET devices structure has a Fin-FET device with a fin of a Si based material. An oxide element is abutting the fin and exerts pressure onto the fin. The Fin-FET device channel is compressively stressed due to the pressure on the fin. A further FET device structure has Fin-FET devices in a row each having fins. An oxide element extending perpendicularly to the row of fins is abutting the fins and exerts pressure onto the fins. Device channels of the Fin-FET devices are compressively stressed due to the pressure on the fins.

    摘要: A method for fabricating an FET device is disclosed. The method includes Fin-FET devices with fins that are composed of a first material, and then merged together by epitaxial deposition of a second material. The fins are vertically recesses using a selective etch. A continuous silicide layer is formed over the increased surface areas of the first material and the second material, leading to smaller resistance. A stress liner overlaying the FET device is afterwards deposited. An FET device is also disclosed, which FET device includes a plurality of Fin-FET devices, the fins of which are composed of a first material. The FET device includes a second material, which is epitaxially merging the fins. The fins are vertically recessed relative to an upper surface of the second material. The FET device furthermore includes a continuous silicide layer formed over the fins and over the second material, and a stress liner covering the device.
