20130069171 | Controlled Fin-Merging for Fin Type FET Devices - A placement of non-planar FET devices is 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. | 03-21-2013 |

The method may include forming a strained channel region in a semiconductor-on-insulator (SOI) substrate including a buried insulator (BOX) layer above a base substrate layer and a SOI layer above the BOX layer by first etching the SOI layer and the BOX layer to form a first isolation recess region and a second isolation recess region. A portion of the SOI layer between the first isolation recess region and the second isolation recess region defines a channel region in the SOI layer. A portion of the base substrate layer below the first isolation recess region and below the second isolation recess region may then be oxidized to form a first oxide region and a second oxide region, respectively, that apply compressive strain to the channel region. | 06-05-2014 |
