  • Patent number: 7955886
    Abstract: A method and apparatus is provided for use in an integrated circuit or printed circuit board for reducing or minimizing interference. An inductance is formed using two or more inductors coupled together and configured such that current flows through the inductors in different directions, thus at least partially canceling magnetic fields. When designing a circuit, the configuration of the inductors, as well as the relative positions of portions of the circuit, can be tweaked to provide optimal interference or noise control.

  • Patent number: 7955972
    Abstract: The present invention addresses this need by providing methods for depositing low resistivity tungsten films in small features and features having high aspect ratios. The methods involve depositing very thin tungsten nucleation layers by pulsed nucleation layer (PNL) processes and then using chemical vapor deposition (CVD) to deposit a tungsten layer to fill the feature. Depositing the tungsten nucleation layer involves exposing the substrate to alternating pulses of a boron-containing reducing agent and a tungsten-containing precursor without using any hydrogen gas, e.g., as a carrier or background gas. Using this process, a conformal tungsten nucleation layer can be deposited to a thickness as small as about 10 Angstroms. The feature may then be wholly or partially filled with tungsten by a hydrogen reduction chemical vapor deposition process. Resistivities of about 14 ??-cm for a 500 Angstrom film may be obtained.

  • Patent number: 7951684
    Abstract: A semiconductor device (1) and a method are disclosed for obtaining on a substrate (2) a multilayer structure (3) with a quantum well structure (4). The quantum well structure (4) comprises a semiconductor layer (5) sandwiched by insulating layers (6,6?), wherein the material of the insulating layers (6,6?) has preferably a high dielectric constant. In a FET the quantum wells (4,9) function as channels, allowing a higher drive current and a lower off current. Short channel effects are reduced. The multi-channel FET is suitable to operate even for sub-35 nm gate lengths. In the method the quantum wells are formed by epitaxial growth of the high dielectric constant material and the semiconductor material alternately on top of each other, preferably with MBE.

  • Patent number: 7951688
    Abstract: A method for obtaining individual dies from a semiconductor structure is disclosed. The semiconductor structure includes a device layer, and the device layer in turn includes active regions separated by predefined spacings. Thick metal is selectively formed on backside of the device layer such that thick metal is formed on backside of active regions but not on backside of the predefined spacings. The semiconductor structure is then cut along the predefined spacings to separate the active regions with thick metal on their backside into individual dies.

  • Patent number: 7948042
    Abstract: A multi-level lithography processes for the fabrication of suspended structures are presented. The process is based on the differential exposure and developing conditions of several a plurality of resist layers, without harsher processes, such as etching of sacrificial layers or the use of hardmasks. These manufacturing processes are readily suited for use with systems that are chemically and/or mechanically sensitive, such as graphene. Graphene p-n-p junctions with suspended top gates formed through these processes exhibit high mobility and control of local doping density and type. This fabrication technique may be further extended to fabricate other types of suspended structures, such as local current carrying wires for inducing local magnetic fields, a point contact for local injection of current, and moving parts in microelectromechanical devices.

  • Patent number: 7943412
    Abstract: A method of formation of a microelectromechanical system (MEMS) resonator or filter which is compatible with integration with any analog, digital, or mixed-signal integrated circuit (IC) process, after or concurrently with the formation of the metal interconnect layers in those processes, by virtue of its materials of composition, processing steps, and temperature of fabrication is presented. The MEMS resonator or filter incorporates a lower metal level, which forms the electrodes of the MEMS resonator or filter, that may be shared with any or none of the existing metal interconnect levels on the IC. It further incorporates a resonating member that is comprised of at least one metal layer for electrical connection and electrostatic actuation, and at least one dielectric layer for structural purposes. The gap between the electrodes and the resonating member is created by the deposition and subsequent removal of a sacrificial layer comprised of a carbon-based material.
