    摘要: A semiconductor structure for a dynamic random access memory (DRAM) cell array that includes a plurality of vertical memory cells built on a semiconductor-on-insulator (SOI) wafer and a body contact electrically coupling a semiconductor body and a semiconductor substrate of the SOI wafer. The semiconductor body includes a channel region for the access device of one of the vertical memory cells. The body contact, which extends through a buried dielectric layer of the SOI wafer, provides a current leakage path that reduces the impact of floating body effects upon the vertical memory cell. The body contact may be formed by etching a via that extends through the semiconductor body and buried dielectric layer of the SOI wafer and extends into the substrate and partially filling the via with a conductive material that electrically couples the semiconductor body with the substrate.

    摘要: Embodiments of the invention generally relate to methods, systems and design structures for semiconductor devices, and more specifically to interconnecting semiconductor devices. A silicide layer may be formed on selective areas of a fin structure connecting one or more semiconductor devices or semiconductor device components. By providing silicided fin structures to locally interconnect semiconductor devices, the use of metal contacts and metal layers may be obviated, thereby allowing formation of smaller, less complex circuits.

    摘要: A semiconductor structure that includes a monocrystalline germanium-containing layer, preferably substantially pure germanium, a substrate, and a buried insulator layer separating the germanium-containing layer from the substrate. A porous layer, which may be porous silicon, is formed on a substrate and a germanium-containing layer is formed on the porous silicon layer. The porous layer may be converted to a layer of oxide, which provides the buried insulator layer. Alternatively, the germanium-containing layer may be transferred from the porous layer to an insulating layer on another substrate. After the transfer, the insulating layer is buried between the latter substrate and the germanium-containing layer.

    摘要: Semiconductor device structures that integrate field effect transistors and bipolar junction transistors on a single substrate, such as a semiconductor-on-insulator substrate, and methods for fabricating such hybrid semiconductor device structures. The field effect and bipolar junction transistors are fabricated using adjacent electrically-isolated semiconductor bodies. During fabrication of the device structures, certain fabrication stages strategically rely on block masks for process isolation. Other fabrication stages are shared during the fabrication process for seamless integration that reduces process complexity.

    摘要: Semiconductor device structures with self-aligned doped regions and methods for forming such semiconductor device structures. The semiconductor structure comprises first and second doped regions of a first conductivity type defined in the semiconductor material of a substrate bordering a sidewall of a trench. An intervening region of the semiconductor material separates the first and second doped regions. A third doped region is defined in the semiconductor material bordering the sidewall of the trench and disposed between the first and second doped regions. The third doped region is doped to have a second conductivity type opposite to the first conductivity type. Methods for forming the doped regions involve depositing either a layer of a material doped with both dopants or different layers each doped with one of the dopants in the trench and, then, diffusing the dopants from the layer or layers into the semiconductor material bordering the trench sidewall.
