摘要： Methodologies and gate etching processes are presented to enable the fabrication of gate conductors of semiconductor devices, such as NFETs and/or PFETs, which are equipped with nano-channels. In one embodiment, a sacrificial spacer of equivalent thickness to the diameter of the gate nano-channel is employed and is deposited after patterning the gate conductor down to the gate dielectric. The residue gate material that is beneath the nano-channel is removed utilizing a medium to high density, bias-free, fluorine-containing or fluorine- and chlorine-containing isotropic etch process without compromising the integrity of the gate. In another embodiment, an encapsulation/passivation layer is utilized. In yet further embodiment, no sacrificial spacer or encapsulation/passivation layer is used and gate etching is performed in an oxygen and nitrogen-free ambient.

摘要： A method includes receiving a signal, which carries data that is encoded with an Error Correction Code (ECC), and correcting the received signal with an adaptive receiver loop. Soft input metrics for the data are computed over the corrected signal. The ECC is decoded using a decoder, which estimates soft output metrics based on the soft input metrics, by operating the decoder in an alternating pattern of external iterations that update one or more of the soft input metrics based on one or more of the soft output metrics, and internal iterations that update the soft output metrics but not the soft input metrics. The adaptive receiver loop is adjusted in a schedule that is defined relative to the pattern of the external and the internal iterations of the decoder.

摘要： Techniques for fabricating nanowire-based devices are provided. In one aspect, a method for fabricating a semiconductor device is provided comprising the following steps. A wafer is provided having a silicon-on-insulator (SOI) layer over a buried oxide (BOX) layer. Nanowires and pads are etched into the SOI layer to form a ladder-like structure wherein the pads are attached at opposite ends of the nanowires. The BOX layer is undercut beneath the nanowires. The nanowires and pads are contacted with an oxidizing gas to oxidize the silicon in the nanowires and pads under conditions that produce a ratio of a silicon consumption rate by oxidation on the nanowires to a silicon consumption rate by oxidation on the pads of from about 0.75 to about 1.25. An aspect ratio of width to thickness among all of the nanowires may be unified prior to contacting the nanowires and pads with the oxidizing gas.

摘要： A method of fabricating a FET device is provided which includes the following steps. Nanowires/pads are formed in a SOI layer over a BOX layer, wherein the nanowires are suspended over the BOX. A HSQ layer is deposited that surrounds the nanowires. A portion(s) of the HSQ layer that surround the nanowires are cross-linked, wherein the cross-linking causes the portion(s) of the HSQ layer to shrink thereby inducing strain in the nanowires. One or more gates are formed that retain the strain induced in the nanowires. A FET device is also provided wherein each of the nanowires has a first region(s) that is deformed such that a lattice constant in the first region(s) is less than a relaxed lattice constant of the nanowires and a second region(s) that is deformed such that a lattice constant in the second region(s) is greater than the relaxed lattice constant of the nanowires.

摘要： Techniques for embedding silicon germanium (e-SiGe) source and drain stressors in nanoscale channel-based field effect transistors (FETs) are provided. In one aspect, a method of fabricating a FET includes the following steps. A doped substrate having a dielectric thereon is provided. At least one silicon (Si) nanowire is placed on the dielectric. One or more portions of the nanowire are masked off leaving other portions of the nanowire exposed. Epitaxial germanium (Ge) is grown on the exposed portions of the nanowire. The epitaxial Ge is interdiffused with Si in the nanowire to form SiGe regions embedded in the nanowire that introduce compressive strain in the nanowire. The doped substrate serves as a gate of the FET, the masked off portions of the nanowire serve as channels of the FET and the embedded SiGe regions serve as source and drain regions of the FET.

摘要： The present disclosure provides a semiconductor structure including a nanoribbon-containing layer of alternating graphene nanoribbons separated by alternating insulating ribbons. The alternating graphene nanoribbons are parallel to a surface of an underlying substrate and, in some embodiments, might be oriented along crystallographic directions of the substrate. The alternating insulating ribbons may comprise hydrogenated graphene, i.e., graphane, fluorinated graphene, or fluorographene. The semiconductor structure mentioned above can be formed by selectively converting portions of an initial graphene layer into alternating insulating ribbons, while the non-converted portions of the initial graphene form the alternating graphene nanoribbons. Semiconductor devices such as, for example, field effect transistors, can be formed atop the semiconductor structure provided in the present disclosure.
