    摘要: An interconnection between a sublithographic-pitched structure and a lithographic pitched structure is formed. A plurality of conductive lines having a sublithographic pitch may be lithographically patterned and cut along a line at an angle less than 45 degrees from the lengthwise direction of the plurality of conductive lines. Alternately, a copolymer mixed with homopolymer may be placed into a recessed area and self-aligned to form a plurality of conductive lines having a sublithographic pitch in the constant width region and a lithographic dimension between adjacent lines at a trapezoidal region. Yet alternately, a first plurality of conductive lines with the sublithographic pitch and a second plurality of conductive lines with the lithographic pitch may be formed at the same level or at different.

    摘要: A method (that produces a structure) patterns at least two wires of semiconductor material such that a first wire of the wires has a larger perimeter than a second wire of the wires. The method performs an oxidation process simultaneously on the wires to form a first gate oxide on the first wire and a second gate oxide on the second wire. The first gate oxide is thicker than the second gate oxide. The method also forms gate conductors over the first gate oxide and the second gate oxide, forms sidewall spacers on the gate conductors, and dopes portions of the first wire and the second wire not covered by the sidewall spacers and the gate conductors to form source and drain regions within the first wire and the second wire.

    摘要: Disclosed are methods and materials including carbon nanotubes which have a strong Raman and/or fluorescent signal and which have been modified with an amphiphilic molecule having available functional linking groups for linking to a biological compound. Exemplified are surface-functionalized SWNTs (single walled nanotubes) as highly sensitive bio-labels based on the detection of their spectroscopic Raman signature. By solubilizing the nanotubes with polyethylene glycol (PEG)-containing phospholipids, aqueous-stable as well as biocompatible SWNT labels are produced. Specificity in biological detection is then attained by immobilizing reporting molecules off this PEG layer. Highly selective detection of surface immobilized proteins is achieved with detection limit of ˜10 femtomolar, three orders of magnitude higher than the fluorescent technique. Signal stability upon Raman readout as well as compatibility of the SWNT-tagged proteins to the microarray protocols are also demonstrated, making these biocompatible SWNTs highly attractive as novel, alternative bio-labels for ultrasensitive detection of proteins. When excited with a near infrared laser, the nanoparticles give off a distinctive fluorescence signal.

    摘要: Techniques for the fabrication of field-effect transistors (FETs) having nanowire channels are provided. In one aspect, a method of fabricating a FET is provided comprising the following steps. A substrate is provided having a silicon-on-insulator (SOI) layer. At least one nanowire is deposited over the SOI layer. A sacrificial gate is formed over the SOI layer so as to cover a portion of the nanowire that forms a channel region. An epitaxial semiconductor material is selectively grown from the SOI layer that covers the nanowire and attaches the nanowire to the SOI layer in a source region and in a drain region. The sacrificial gate is removed. An oxide is formed that divides the SOI layer into at least two electrically isolated sections, one section included in the source region and the other section included in the drain region. A gate dielectric layer is formed over the channel region. A gate is formed over the channel region separated from the nanowire by the gate dielectric layer. A metal-semiconductor alloy is formed over the source and drain regions.
