Abstract: A non-planar transistor including partially melted raised semiconductor source/drains disposed on opposite ends of a semiconductor fin with the gate stack disposed there between. The raised semiconductor source/drains comprise a super-activated dopant region above a melt depth and an activated dopant region below the melt depth. The super-activated dopant region has a higher activated dopant concentration than the activated dopant region and/or has an activated dopant concentration that is constant throughout the melt region. A fin is formed on a substrate and a semiconductor material or a semiconductor material stack is deposited on regions of the fin disposed on opposite sides of a channel region to form raised source/drains. A pulsed laser anneal is performed to melt only a portion of the deposited semiconductor material above a melt depth.

Abstract: Integrated circuit structures having source or drain structures and germanium N-channels are described. In an example, an integrated circuit structure includes a fin having a lower fin portion and an upper fin portion, the upper fin portion including germanium. A gate stack is over the upper fin portion of the fin. A first source or drain structure includes an epitaxial structure embedded in the fin at a first side of the gate stack. A second source or drain structure includes an epitaxial structure embedded in the fin at a second side of the gate stack. Each epitaxial structure includes a first semiconductor layer in contact with the upper fin portion, and a second semiconductor layer on the first semiconductor layer. The first semiconductor layer comprises silicon, germanium and phosphorous, and the second semiconductor layer comprises silicon and phosphorous.

Abstract: Embodiments of the disclosure are in the field of advanced integrated circuit structure fabrication and, in particular, integrated circuit structures having germanium-based channels are described. In an example, an integrated circuit structure includes a fin having a lower silicon portion, an intermediate germanium portion on the lower silicon portion, and a silicon germanium portion on the intermediate germanium portion. An isolation structure is along sidewalls of the lower silicon portion of the fin. A gate stack is over a top of and along sidewalls of an upper portion of the fin and on a top surface of the isolation structure. A first source or drain structure is at a first side of the gate stack. A second source or drain structure is at a second side of the gate stack.

Abstract: Embodiments herein describe techniques, systems, and method for a semiconductor device. Embodiments herein may present a semiconductor device including a substrate with a surface that is substantially flat. A channel area including an III-V compound may be above the substrate, where the channel area is an epitaxial layer directly in contact with the surface of the substrate. A gate dielectric layer is adjacent to the channel area and in direct contact with the channel area, while a gate electrode is adjacent to the gate dielectric layer. Other embodiments may be described and/or claimed.

Abstract: A buffer layer is deposited on a substrate. A first III-V semiconductor layer is deposited on the buffer layer. A second III-V semiconductor layer is deposited on the first III-V semiconductor layer. The second III-V semiconductor layer comprises a channel portion and a source/drain portion. The first III-V semiconductor layer acts as an etch stop layer to etch a portion of the second III-V semiconductor layer to form the source/drain portion.
