Abstract: A DRAM integrated circuit device is described in which at least some of the peripheral circuits associated with the memory arrays are provided on a first substrate. The memory arrays are provided on a second substrate stacked on the first substrate, thus forming a DRAM integrated circuit device on a stacked-substrate assembly. Vias that electrically connect the memory arrays on the second substrate to the peripheral circuits on the first substrate are fabricated using high aspect ratio via fabrication techniques.

Abstract: Embodiments herein describe techniques for a semiconductor device over a semiconductor substrate. A first bonding layer is above the semiconductor substrate. One or more nanowires are formed above the first bonding layer to be a channel layer. A gate electrode is around a nanowire, where the gate electrode is in contact with the first bonding layer and separated from the nanowire by a gate dielectric layer. A source electrode or a drain electrode is in contact with the nanowire, above a bonding area of a second bonding layer, and separated from the gate electrode by a spacer, where the second bonding layer is above and in direct contact with the first bonding layer.

Abstract: The present description relates to the fabrication of microelectronic transistor source and/or drain regions using angled etching. In one embodiment, a microelectronic transistor may be formed by using an angled etch to reduce the number masking steps required to form p-type doped regions and n-type doped regions. In further embodiments, angled etching may be used to form asymmetric spacers on opposing sides of a transistor gate, wherein the asymmetric spacers may result in asymmetric source/drain configurations.

Abstract: Multiple non-silicon semiconductor material layers may be stacked within a fin structure. The multiple non-silicon semiconductor material layers may include one or more layers that are suitable for P-type transistors. The multiple non-silicon semiconductor material layers may further include one or more one or more layers that are suited for N-type transistors. The multiple non-silicon semiconductor material layers may further include one or more intervening layers separating the N-type from the P-type layers. The intervening layers may be at least partially sacrificial, for example to allow one or more of a gate, source, or drain to wrap completely around a channel region of one or more of the N-type and P-type transistors.

Abstract: Stacked transistor structures and methods of forming same. In an embodiment, a stacked transistor structure has a wide central pedestal region and at least one relatively narrower channel region above and/or below the wider central pedestal region. The upper and lower channel regions are configured with a non-planar architecture, and include one or more semiconductor fins, nanowires, and/or nanoribbons. The top and bottom channel regions may be configured the same or differently, with respect to shape and/or semiconductor materials. In some cases, an outermost sidewall of one or both the top and/or bottom channel region structures, is collinear with an outermost sidewall of the wider central pedestal region. In some such cases, the outermost sidewall of the top channel region structure is collinear with the outermost sidewall of the bottom channel region structure. Top and bottom transistor structures (NMOS/PMOS) may be formed using the top and bottom channel region structures.

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.
