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.
