An example embodiments are structures and methods for forming an FET with embedded stressor S/D regions (e.g., SiGe), a doped layer below the embedded S/D region adjacent to the isolation regions, and a stressor liner over reduced spacers of the FET gate. An example method comprising the following. We provide a gate structure over a first region in a substrate. The gate structure is comprised of gate dielectric, a gate, and sidewall spacers. We provide isolation regions in the first region spaced from the gate structure; and a channel region in the substrate under the gate structure. We form S/D recesses in the first region in the substrate adjacent to the sidewall spacers. We form S/D stressor regions filling the S/D recesses. The S/D stressor regions can be thicker adjacent to the gate structure than adjacent to the isolation regions; We implant dopant ions into the S/D stressor regions and into the substrate below the S/D stressor regions adjacent to the isolation regions to form upper stressor doped regions.

An opto-thermal annealing method for forming a field effect transistor uses a reflective metal gate so that electrical properties of the metal gate and also interface between the metal gate and a gate dielectric are not compromised when opto-thermal annealing a source/drain region adjacent the metal gate. Another opto-thermal annealing method may be used for simultaneously opto-thermally annealing: (1) a silicon layer and a silicide forming metal layer to form a fully silicided gate; and (2) a source/drain region to form an annealed source/drain region. An additional opto-thermal annealing method may use a thermal insulator layer in conjunction with a thermal absorber layer to selectively opto-thermally anneal a silicon layer and a silicide forming metal layer to form a fully silicide gate.
摘要:
Integrated circuits are oriented on a substrate at an angle that is rotated between 0 to 45 degrees from a direction parallel or perpendicular to a preferred crystalline plane direction, such as the cleavage plane, of the substrate. Parameters such as stress and mobility of transistors may be optimized by adjusting the angle of rotation of the substrate. For a rotated substrate CMOS device design, other stress control measures may be used, such as a stress control or tensile liner, over an NMOS transistor, PMOS transistor, or both, to further adjust the stress and improve performance.

Integrated circuits are oriented on a substrate at an angle that is rotated between 5 to 40 degrees from a direction parallel or perpendicular to a preferred crystalline plane direction, such as the cleavage plane, of the substrate. Parameters such as stress and mobility of transistors may be optimized by adjusting the angle of rotation of the substrate. For a rotated substrate CMOS device design, other stress control measures may be used, such as a stress control or tensile liner, over an NMOS transistor, PMOS transistor, or both, to further adjust the stress and improve performance.

A system for using recent activity information to select backup versions of storage objects for restoration comprises a processor and memory coupled to the processor, where the memory stores program instructions computer-executable by the processor to implement a backup manager. The backup manager is configured to maintain one or more backup versions of a plurality of storage objects and a plurality of access history records, where each access history record is associated with a particular backup version. Each access history record includes information indicative of an access to the corresponding storage object by a user. The backup manager may be configured to select a particular backup version as a restoration candidate using at least the contents of the access history record associated with the backup version.

A semiconducting material that has all the advantages of prior art SOI substrates including, for example, low parasitic capacitance and leakage, without having floating body effects is provided. More specifically, the present invention provides a Semiconductor-on-Pores (SOP) material that includes a top semiconductor layer and a bottom semiconductor layer, wherein the semiconductor layers are separated in at least one region by a porous semiconductor material. Semiconductor structures including the SOP material as a substrate as well as a method of fabricating the SOP material are also provided. The method includes forming a p-type region with a first semiconductor layer, converting the p-type region to a porous semiconductor material, sealing the upper surface of the porous semiconductor material by annealing, and forming a second semiconductor layer atop the porous semiconductor material.

A chip is provided which includes an active semiconductor region and a field effect transistor (“FET”) having a channel region, a source region and a drain region all disposed within the active semiconductor region. The FET has a longitudinal direction in a direction of a length of the channel region, and a transverse direction in a direction of a width of the channel region. A first dielectric stressor element having a horizontally extending upper surface extends below a portion of the active semiconductor region, such as a northwest portion of the active semiconductor region. A second dielectric stressor element having a horizontally extending upper surface extends below a second portion of the active semiconductor region, such as a southeast portion of the active semiconductor region. Each of the first and second dielectric stressor elements shares an edge with the active semiconductor region, the edges extending in directions away from the upper surface.
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.
