Disclosed herein are source/drain regions in integrated circuit (IC) structures, as well as related methods and components. For example, in some embodiments, an IC structure may include: a channel region including a semiconductor material; and a source/drain region at a side face of the channel region, wherein the source/drain region includes a semiconductor portion and a contact metal, and the semiconductor portion is between the contact metal and the semiconductor material.

Source/drain regions in integrated circuit structures

Vertical integration schemes and circuit elements architectures for area scaling of semiconductor devices are described. In an example, an inverter structure includes a semiconductor fin separated vertically into an upper region and a lower region. A first plurality of gate structures is included for controlling the upper region of the semiconductor fin. A second plurality of gate structures is included for controlling the lower region of the semiconductor fin. The second plurality of gate structures has a conductivity type opposite the conductivity type of the first plurality of gate structures.

Vertical integration scheme and circuit elements architecture for area scaling of semiconductor devices

Gate-all-around integrated circuit structures having an insulator fin on an insulator substrate, and methods of fabricating gate-all-around integrated circuit structures having an insulator fin on an insulator substrate, are described. For example, an integrated circuit structure includes an insulator fin on an insulator substrate. A vertical arrangement of horizontal semiconductor nanowires is over the insulator fin. A gate stack surrounds a channel region of the vertical arrangement of horizontal semiconductor nanowires, and the gate stack is overlying the insulator fin. A pair of epitaxial source or drain structures is at first and second ends of the vertical arrangement of horizontal semiconductor nanowires and at first and second ends of the insulator fin.

Gate-all-around integrated circuit structures having insulator fin on insulator substrate

Embodiments disclosed herein include forksheet transistor devices having a dielectric or a conductive spine. For example, an integrated circuit structure includes a dielectric spine. A first transistor device includes a first vertical stack of semiconductor channels spaced apart from a first edge of the dielectric spine. A second transistor device includes a second vertical stack of semiconductor channels spaced apart from a second edge of the dielectric spine. An N-type gate structure is on the first vertical stack of semiconductor channels, a portion of the N-type gate structure laterally between and in contact with the first edge of the dielectric spine and the first vertical stack of semiconductor channels. A P-type gate structure is on the second vertical stack of semiconductor channels, a portion of the P-type gate structure laterally between and in contact with the second edge of the dielectric spine and the second vertical stack of semiconductor channels.

Forksheet transistors with dielectric or conductive spine

Fin doping, and integrated circuit structures resulting therefrom, are described. In an example, an integrated circuit structure includes a semiconductor fin. A lower portion of the semiconductor fin includes a region having both N-type dopants and P-type dopants with a net excess of the P-type dopants of at least 2E18 atoms/cm. A gate stack is over and conformal with an upper portion of the semiconductor fin. A first source or drain region is at a first side of the gate stack, and a second source or drain region is at a second side of the gate stack opposite the first side of the gate stack.

Fin doping and integrated circuit structures resulting therefrom

Material systems for source region, drain region, and a semiconductor body of transistor devices in which the semiconductor body is electrically insulated from an underlying substrate are selected to reduce or eliminate a band to band tunneling ('BTBT') effect between different energetic bands of the semiconductor body and one or both of the source region and the drain region. This can be accomplished by selecting a material for the semiconductor body with a band gap that is larger than a band gap for material(s) selected for the source region and/or drain region.

Reducing off-state leakage in semiconductor devices

Embodiments of the present disclosure are based on extending a nanocomb transistor architecture to implement gate all around, meaning that a gate enclosure of at least a gate dielectric material, or both a gate dielectric material and a gate electrode material, is provided on all sides of each nanoribbon of a vertical stack of lateral nanoribbons of a nanocomb transistor arrangement. In particular, extension of a nanocomb transistor architecture to implement gate all around, proposed herein, involves use of two dielectric wall materials which are etch-selective with respect to one another, instead of using only a single dielectric wall material used to implement conventional nanocomb transistor arrangements. Nanocomb-based transistor arrangements implementing gate all around as described herein may provide improvements in terms of the short-channel effects of conventional nanocomb transistor arrangements.

Extension of nanocomb transistor arrangements to implement gate all around

Semiconductor nanowire devices having (111)-plane channel sidewalls and methods of fabricating semiconductor nanowire devices having (111)-plane channel sidewalls are described. For example, an integrated circuit structure includes a first semiconductor device including a plurality of vertically stacked nanowires disposed above a substrate, each of the nanowires comprising a discrete channel region having <111> lateral sidewalls along a <110> carrier transport direction. The integrated circuit structure also includes a second semiconductor device including a semiconductor fin disposed above the substrate, the semiconductor fin having a channel region with a top and side surfaces, the channel region having <111> lateral sidewalls along a <110> carrier transport direction.

Semiconductor nanowire device having (111)-plane channel sidewalls

Embodiments herein describe techniques for a thin-film transistor (TFT) above a substrate. The transistor includes a gate electrode above the substrate, and a channel layer above the substrate, separated from the gate electrode by a gate dielectric layer. The transistor further includes a contact electrode above the channel layer and in contact with a contact area of the channel layer. The contact area has a thickness determined based on a Schottky barrier height of a Schottky barrier formed at an interface between the contact electrode and the contact area, a doping concentration of the contact area, and a contact resistance at the interface between the contact electrode and the contact area. Other embodiments may be described and/or claimed.

Channel structures for thin-film transistors

Nanowire structures having wrap-around contacts are described. For example, a nanowire semiconductor device includes a nanowire disposed above a substrate. A channel region is disposed in the nanowire. The channel region has a length and a perimeter orthogonal to the length. A gate electrode stack surrounds the entire perimeter of the channel region. A pair of source and drain regions is disposed in the nanowire, on either side of the channel region. Each of the source and drain regions has a perimeter orthogonal to the length of the channel region. A first contact completely surrounds the perimeter of the source region. A second contact completely surrounds the perimeter of the drain region.

Nanowire structures having wrap-around contacts

An apparatus is provided which comprises: a first region over a substrate, wherein the first region comprises a first semiconductor material having a L-valley transport energy band structure, a second region in contact with the first region at a junction, wherein the second region comprises a second semiconductor material having a X-valley transport energy band structure, wherein a &#x3c;111&#x3e; crystal direction of one or more crystals of the first and second semiconductor materials are substantially orthogonal to the junction, and a metal adjacent to the second region, the metal conductively coupled to the first region through the junction. Other embodiments are also disclosed and claimed.
