Abstract: Deep gate-all-around semiconductor devices having germanium or group III-V active layers are described. For example, a non-planar semiconductor device includes a hetero-structure disposed above a substrate. The hetero-structure includes a hetero-junction between an upper layer and a lower layer of differing composition. An active layer is disposed above the hetero-structure and has a composition different from the upper and lower layers of the hetero-structure. A gate electrode stack is disposed on and completely surrounds a channel region of the active layer, and is disposed in a trench in the upper layer and at least partially in the lower layer of the hetero-structure. Source and drain regions are disposed in the active layer and in the upper layer, but not in the lower layer, on either side of the gate electrode stack.

Abstract: An embodiment includes depositing a material onto a substrate where the material includes a different lattice constant than the substrate (e.g., III-V or IV epitaxial (EPI) material on a Si substrate). An embodiment includes an EPI layer formed within a trench having walls that narrow as the trench extends upwards. An embodiment includes an EPI layer formed within a trench using multiple growth temperatures. A defect barrier, formed in the EPI layer when the temperature changes, contains defects within the trench and below the defect barrier. The EPI layer above the defect barrier and within the trench is relatively defect free. An embodiment includes an EPI layer annealed within a trench to induce defect annihilation. An embodiment includes an EPI superlattice formed within a trench and covered with a relatively defect free EPI layer (that is still included in the trench). Other embodiments are described herein.

Abstract: 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.

Abstract: Techniques are disclosed for forming a non-planar germanium quantum well structure. In particular, the quantum well structure can be implemented with group IV or III-V semiconductor materials and includes a germanium fin structure. In one example case, a non-planar quantum well device is provided, which includes a quantum well structure having a substrate (e.g. SiGe or GaAs buffer on silicon), a IV or III-V material barrier layer (e.g., SiGe or GaAs or AlGaAs), a doping layer (e.g., delta/modulation doped), and an undoped germanium quantum well layer. An undoped germanium fin structure is formed in the quantum well structure, and a top barrier layer deposited over the fin structure. A gate metal can be deposited across the fin structure. Drain/source regions can be formed at respective ends of the fin structure.
