    摘要： A method for fabricating FET devices is disclosed. The method includes forming continuous fins of a semiconductor material and fabricating gate structures overlaying the continuous fins. After the fabrication of the gate structures, the method uses epitaxial deposition to merge the continuous fins to one another. Next, the continuous fins are cut into segments. The fabricated FET devices are characterized as being non-planar devices. A placement of non-planar FET devices is also disclosed, which includes non- planar devices that have electrodes, and the electrodes contain fins and an epitaxial layer which merges the fins together. The non-planar devices are so placed that their gate structures are in a parallel configuration separated from one another by a first distance, and the fins of differing non-planar devices line up in essentially straight lines. The electrodes of differing FET devices are separated from one another by a cut defined by opposing facets of the electrodes, with the opposing facets also defining the width of the cut. The width of the cut is smaller than one fifth of the first distance which separates the gate structures.

    摘要： A semiconductor device and method for forming the semiconductor device include forming structures in a semiconductor substrate. The structures have two or more different spacings between them. A dielectric material is deposited in the spacings. Ion species are implanted to a depth in the dielectric material to change an etch rate of the dielectric material down to the depth. The dielectric material having the ion species is etched selective to the dielectric material below the depth such that a substantially uniform depth in the dielectric material is created across the at least two spacings.

    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 device and method for fabrication of fin devices for an integrated circuit includes forming fin structures in a semiconductor material of a semiconductor device wherein the semiconductor material is exposed on sidewalls of the fin structures. A donor material is epitaxially deposited on the exposed sidewalls of the fin structures. A condensation process is applied to move the donor material through the sidewalls into the semiconductor material such that accommodation of the donor material causes a strain in the semiconductor material of the fin structures. The donor material is removed, and a field effect transistor is formed from the fin structure.
