20100181648LOCALIZED SYNTHESIS AND SELF-ASSEMBLY OF NANOSTRUCTURES - Systems and methods for local synthesis of silicon nanowires and carbon nanotubes, as well as electric field assisted self-assembly of silicon nanowires and carbon nanotubes, are described. By employing localized heating in the growth of the nanowires or nanotubes, the structures can be synthesized on a device in a room temperature chamber without the device being subjected to overall heating. The method is localized and selective, and provides for a suspended microstructure to achieve the thermal requirement for vapor deposition synthesis, while the remainder of the chip or substrate remains at room temperature. Furthermore, by employing electric field assisted self-assembly techniques according to the present invention, it is not necessary to grow the nanotubes and nanowires and separately connect them to a device. Instead, the present invention provides for self-assembly of the nanotubes and nanowires on the devices themselves, thus providing for nano- to micro-integration.07-22-2010
20100214185PLASTIC WAVEGUIDE-FED HORN ANTENNA - A plastic, waveguide-fed, horn antenna is manufactured using a three-dimensional (3D), polymeric micro hot embossing process. Two cavity resonators may be designed to reduce the impedance mismatch between the pyramidal horn antenna and the feeding waveguide. The waveguide-fed antenna may be fabricated using a self-aligned 3D plastic hot embossing process followed by a selective electroplating and sealing process to coat an approximately 8 μm-thick gold layer around the internal surfaces of the system. As such, this plastic, low-cost manufacturing process may be used to replace the expensive metallic components for millimeter-wave systems and provides a scalable and integrated process for manufacturing an array of antenna.08-26-2010
20100238085PLASTIC WAVEGUIDE SLOT ARRAY AND METHOD OF MANUFACTURE - The present invention discloses a waveguide antenna structure and a method of manufacture. The waveguide antenna structure can include a non-metallic substrate having a waveguide channel extending along a first direction and an inlet channel extending along a second direction. The inlet channel intersects with the waveguide channel and both channels are at least partially coated with a metallic material. The waveguide channel can have a generally U-shaped cross-section with an open side that is at partially enclosed by a slot plate that is attached to the non-metallic substrate.09-23-2010
20110241201Radiate Under-Bump Metallization Structure for Semiconductor Devices - An under-bump metallization (UBM) structure for a semiconductor device is provided. The UBM structure has a center portion and extensions extending out from the center portion. The extensions may have any suitable shape, including a quadrangle, a triangle, a circle, a fan, a fan with extensions, or a modified quadrangle having a curved surface. Adjacent UBM structures may have the respective extensions aligned or rotated relative to each other. Flux may be applied to a portion of the extensions to allow an overlying conductive bump to adhere to a part of the extensions.10-06-2011

20080317464Base Station System - The present invention discloses a base station system, including an indoor part and a remote RF subsystem (RRS). The indoor part includes a RIU, a CCU, a BBU, a GPSU and a local interface unit. The RRS includes a remote interface unit, a RF transceiver unit (TRU) and an antenna. The local interface unit and the remote interface unit are for signal intercommunicating between the indoor part of the base station and the RSS. The TRU is a RF transceiver module of the conventional RFU, for amplifying an analog RF signal from the remote interface unit and transmitting the signal to the antenna. By flexibly selecting between an optical cable and an If cable, the interface unit of the present invention provides a digital baseband remote manner and an IF remote manner. According to the structure of the base station of the present invention, the number of the base station sites and the network operating cost decreases; on the other side, since one base station may cover a cell by smart antenna with only one optical cable or IF cable, the difficulty in mounting is reduced.12-25-2008
