Abstract:
A film bulk acoustic resonator filter may be formed with a plurality of interconnected series and shunt film bulk acoustic resonators formed on the same membrane. Each of the film bulk acoustic resonators may be formed from a common lower conductive layer which is defined to form the bottom electrode of each film bulk acoustic resonator. A common top conductive layer may be defined to form each top electrode of each film bulk acoustic resonator. A common piezoelectric film layer, that may or may not be patterned, forms a continuous or discontinuous film.
Abstract:
The methods, compositions and apparatus disclosed herein are of use for nucleic acid sequence determination. The methods involve isolation of one or more nucleic acid template molecules and polymerization of a nascent complementary strand of nucleic acid, using a DNA or RNA polymerase or similar synthetic reagent. As the nascent strand is extended one nucleotide at a time, the disappearance of nucleotide precursors from solution is monitored by Raman spectroscopy or FRET. The nucleic acid sequence of the nascent strand, and the complementary sequence of the template strand, may be determined by tracking the order of incorporation of nucleotide precursors during the polymerization reaction. Certain embodiments concern apparatus comprising a reaction chamber and detection unit, of use in practicing the claimed methods. The methods, compositions and apparatus are of use in sequencing very long nucleic acid templates in a single sequencing reaction.
Abstract:
This invention relates to inductive inertial sensors employing a magnetic drive and/or sense architecture. In embodiments, translational gyroscopes utilize a conductive coil made to vibrate in a first dimension as a function of a time varying current driven through the coil in the presence of a magnetic field. Sense coils register an inductance that varies as a function of an angular velocity in a second dimension. In embodiments, the vibrating coil causes first and second mutual inductances in the sense coils to deviate from each other as a function of the angular velocity. In embodiments, self-inductances associated with a pair of meandering coils vary as a function of an angular velocity in a second dimension. In embodiments, package build-up layers are utilized to fabricate the inductive inertial sensors, enabling package-level integrated inertial sensing advantageous in small form factor computing platforms, such as mobile devices.

Abstract:
A method and apparatus for forming a polymer array on a substrate suitable for synthesizing polymer sequences. This includes forming an array, each location of the array having at least one strand end, forming photosensitive protection on the strand ends, and selectively scanning and modulating at least one energy beam to expose a pattern on the photosensitive protection. In some embodiments, the method further includes removing a protective group from selected strand ends based on the exposed pattern. The method then includes adding a predetermined one or more polymeric subunits to the deprotected strand ends. In some embodiments the photosensitive protection includes a layer of photoresist to cover the strand ends. Some embodiments use an ultra-violet laser.
Abstract:
A MEMS device may be formed in a hermetic cavity by sealing a pair of semiconductor structures to one another, enclosing the MEMS device. The two structures may be coupled using surface mount techniques as one example, so that the temperatures utilized may be compatible with many MEMS applications. Electrical interconnection layers in one or the other of these structures may be utilized to allow electrical interconnections from the exterior world to the MEMS components within the cavity.
Abstract:
A film bulk acoustic resonator is formed on a substrate having a major surface. The film bulk acoustic resonator includes an elongated stack. The elongated stack includes a layer of piezoelectric material positioned between a first conductive layer deposited on a first surface of the layer of piezoelectric material, and a second conductive layer deposited on a second surface of the layer of piezoelectric material. The elongated stack is positioned substantially perpendicular with respect to the major surface of the substrate. The first and second conductive layers are placed on the layer of piezoelectric material substantially simultaneously and in one processing step. The major surface of the substrate is in a horizontal plane and the stack of the film bulk acoustic resonator is in a substantially vertical plane. The resonator structure formed may be used either as a resonator or a filter.

Abstract:
Ein-Chip-System-(SoC-)Lösungen, die einen RFIC in einen PMIC mithilfe einer Transistortechnologie integrieren, die auf Gruppe III-Nitriden (III-N) beruht und die in der Lage ist, eine hohe Ft und ebenfalls eine ausreichend hohe Durchschlagsspannung (BV) zu erzielen, um Hochspannungs- und/oder Hochleistungsschaltungen auszuführen. In Ausführungsformen ist die III-N-Transistor-Architektur skalierbar, um Leistungsverbesserungen über viele nachfolgende Gerätegenerationen tragen zu können. In Ausführungsformen ist die III-N-Transistor-Architektur in Gruppe IV-Transistor-Architekturen monolithisch integrierbar, wie Planare und nichtplanare Silicium-CMOS-Transistortechnologien. Planare und nichtplanare HEMT-Ausführungsformen mit einem oder mehreren vertieften Gates, symmetrischer Source und symmetrischem Drain, neu gewachsenen Source/Drain werden mit einem Austausch-Gate-Verfahren gebildet, das einen Betrieb im Anreicherungsmodus und gute Gate-Passivierung gestattet.
Abstract:
Multiple FBARs may be manufactured on a single wafer and later diced. Ideally, all devices formed in a wafer would have the same resonance frequency. However, due to manufacturing variances, the frequency response of the FBAR devices may vary slightly across the wafer. An RF map may be created to determine zones over the wafer where FBARs in that zone all vary from a target frequency by a similar degree. A tuning layer may be deposited over the wafer. Lithographically patterned features to the tuning layer based on the zones identified by the RF map may be used to correct the FBARs to a target resonance frequency with the FBARs still intact on the wafer.
