    摘要: A method for adjusting the frequency of a piezoelectic resonator such as a quartz crystal is disclosed. The resonator is placed within its enclosure facing a metallic surface. The atmosphere within the enclosure is made suitable for supporting a glow discharge. An electrical potential is then established between the resonator electrode and the metallic surface causing mass to sputter between the electrode and to the metallic surface to vary the characteristics of the resonator.

    摘要: A cognitive radio (CR) system (102) includes CR units (108, 110) that determine and update location-based system operating parameters to avoid interference with other systems operating in the same frequency band. Operational Location Uncertainty region and Allowed Location Error regions can be applied. The CR unit trades off between both, available channels and maximum system operating parameters, such that as Location Uncertainty of the CR device increases, available CR channels and location-based CR system operating parameters decrease over a maximum network reach.

    摘要: A three-dimensional inductor coil is fabricated on top of a semiconductor substrate. The fabrication process includes the steps of depositing a first photoresist layer (406), forming a trench therein, and filling the trench with electroplated metal (404). A second photoresist layer (408) is deposited, and first and second trenches (410) are formed therein and filled with electroplated metal (412). A third photoresist layer (416) is deposited and a trench (418) formed therein, and then filled with electroplated metal (420). The first, second, and third photoresist layers (406, 408, 416) are then removed to expose a multi-loop inductor coil (500, 550).

    摘要: One method for fabricating solderable pads (406) onto a substrate (220) for direct chip attachment uses a multilayer metallization coating (500). The coating has a bottom layer (202) of indium-tin oxide, with an intermediate layer (204) of copper and a top layer (206) of indium-tin oxide. A masking layer (208) is deposited on the active display area (402) of the substrate, leaving the bonding pads uncovered. The revealed bonding pads are then plasma etched, using the polyimide as an etch resist, and the top layer of ITO is selectively removed to reveal the underlying copper layer. The exposed copper layer (204) is then plated with a solderable metal to the desired thickness to form bonding pads that may be used with direct chip attachment schemes.

    摘要: A method of forming high resolution circuit features on a substrate. A `seed` layer of copper (110) is deposited on a dielectric substrate (100). A dielectric layer (120) is then deposited on the copper layer, and an aluminum `mask` layer (130) is deposited on the dielectric layer. A photoresist layer (140) is spun on or laminated to the aluminum. The photoresist layer is imaged and developed to define a circuit pattern such that portions (230) of the aluminum `mask` layer are revealed, and these revealed portions are further etched so as to reveal portions (320) of the dielectric layer that are directly underneath. The remaining portions of the photoresist layer are stripped away, along with the revealed underlying portions of the dielectric film, exposing portions (410) of the copper layer in the image of the circuit pattern. The remaining portions of the aluminum mask are then removed, and the exposed copper is then electroplated to form the desired circuit traces (600). The remaining portions of the dielectric layer are stripped to expose the unplated portions of the copper layer, and these unplated portions are etched away with acid.

    摘要: A twisted-pair conductor line structure is formed on a substrate (22) having insulated conductive layers (10, 11). The conductive layers are used to form first, second, third, and fourth conductive planar segments (16). A first conductive link (17) joins the first and second planar conductive segments to provide a first signal path. Similarly, a second conductive link (17) joins the third and fourth planar conductive segments to provide a second signal path. The first and second conductive links are operatively arranged to form a twist (17)in the first and second signal paths, such that the resulting magnetic fields (57, 59) around the twisted conductive segments will be opposite to each other for cancelling each other out, in order to reduce the magnetic field radiation to the surrounding environment.
