摘要： An embodiment of the invention includes an epitaxial layer that directly contacts, for example, a nanowire, fin, or pillar in a manner that allows the layer to relax with two or three degrees of freedom. The epitaxial layer may be included in a channel region of a transistor. The nanowire, fin, or pillar may be removed to provide greater access to the epitaxial layer. Doing so may allow for a “all-around gate” structure where the gate surrounds the top, bottom, and sidewalls of the epitaxial layer. Other embodiments are described herein.

摘要： Techniques are disclosed for enabling multi-sided condensation of semiconductor fins. The techniques can be employed, for instance, in fabricating fin-based transistors. In one example case, a strain layer is provided on a bulk substrate. The strain layer is associated with a critical thickness that is dependent on a component of the strain layer, and the strain layer has a thickness lower than or equal to the critical thickness. A fin is formed in the substrate and strain layer, such that the fin includes a substrate portion and a strain layer portion. The fin is oxidized to condense the strain layer portion of the fin, so that a concentration of the component in the strain layer changes from a pre-condensation concentration to a higher post-condensation concentration, thereby causing the critical thickness to be exceeded.

摘要： Contacts to n-type source/drain regions comprise a phosphide or arsenide metal compound layer. The phosphide or arsenide metal compound layers can aid in forming thermally stable low resistance contacts. A phosphide or arsenide metal compound layer is positioned between the source/drain region and the contact metal layer of the contact. A phosphide or arsenic metal compound layer can be used in contacts contacting n-type source/drain regions comprising phosphorous or arsenic as the primary dopant, respectively. The phosphide or arsenide metal compound layers prevent diffusion of phosphorous or arsenic from the source/drain region into the metal contact layer and dopant deactivation in the source/drain region due to annealing and other high-temperature processing steps that occur after contact formation. Phosphide and arsenide metal contact layers can also reduce the amount of silicide that forms in source/drain regions during processing by limiting the amount of contact metal that diffuses into source/drain regions.

摘要： A transistor includes a semiconductor fin with a subfin layer of a subfin material selected from a first group III-V compound a channel layer of a channel material directly on the subfin layer and extending upwardly therefrom, the channel material being a second group III-V compound different from the first group III-V compound. A gate structure is in direct contact with the channel layer of the semiconductor fin, where the gate structure is further in direct contact with one of (i) a top surface of the subfin layer, the top surface being exposed where the channel layer meets the subfin layer because the channel layer is narrower than the subfin layer, or (ii) a liner layer of liner material in direct contact with opposing sidewalls of the subfin layer, the liner material being distinct from the first and second group III-V compounds.

摘要： An embodiment uses a very thin layer nanostructure (e.g., a Si or SiGe fin) as a template to grow a crystalline, non-lattice matched, epitaxial (EPI) layer. In one embodiment the volume ratio between the nanostructure and EPI layer is such that the EPI layer is thicker than the nanostructure. In some embodiments a very thin bridge layer is included between the nanostructure and EPI. An embodiment includes a CMOS device where EPI layers covering fins (or that once covered fins) are oppositely polarized from one another. An embodiment includes a CMOS device where an EPI layer covering a fin (or that once covered a fin) is oppositely polarized from a bridge layer covering a fin (or that once covered a fin). Thus, various embodiments are disclosed from transferring defects from an EPI layer to a nanostructure (that is left present or removed). Other embodiments are described herein.
