摘要: A semiconductor device is presented which is composed of two adjacent semiconductor chips. Each semiconductor chip has an integrated half-wave dipole antenna structure located thereon. The semiconductor chips are oriented so that the half-wave dipole antenna segments extend away from each other, allowing the segments to be effectively mated and thus form a complete full-wave dipole antenna. The two solder bumps which form the antenna are separated by a gap of approximately 200 microns. The length of each solder bump antenna is based on the wavelength and the medium of collection. Phased array antenna arrays may also be constructed from a plurality of these semiconductor chip antennae.

摘要: A micro-electro mechanical switch having a restoring force sufficiently large to overcome stiction is described. The switch is provided with a deflectable conductive beam and multiple electrodes coated with an elastically deformable conductive layer. A restoring force which is initially generated by a single spring constant k0 upon the application of a control voltage between the deflectable beam and a control electrode coplanar to the contact electrodes is supplemented by adding to k0 additional spring constants k1, . . . , kn provided by the deformable layers, once the switch nears closure and the layers compress. In another embodiment, deformable, spring-like elements are used in lieu of the deformable layers. In an additional embodiment, the compressible layers or deformable spring-like elements are affixed to the deflecting beam facing the switch electrodes

摘要: Disclosed is a capacitive electrostatic MEMS RF switch comprised of a lower electrode that acts as both a transmission line and as an actuation electrode. Also, there is an array of one or more fixed beams above the lower electrode that is connected to ground. The lower electrode transmits the RF signal when the top beam or beams are up and when the upper beams are actuated and bent down, the transmission line is shunted to ground ending the RF transmission. A high dielectric constant material is used in the capacitive portion of the switch to achieve a high capacitance per unit area thus reducing the required chip area and enhancing the insertion loss characteristics in the non-actuated state. A gap between beam and lower electrode of less than 1 &mgr;m is incorporated in order to minimize the electrostatic potential (pull-in voltage) required to actuate the switch.

摘要: A micro-electromechanical (MEM) RF switch provided with a deflectable membrane (60) activates a switch contact or plunger (40). The membrane incorporates interdigitated metal electrodes (70) which cause a stress gradient in the membrane when activated by way of a DC electric field. The stress gradient results in a predictable bending or displacement of the membrane (60), and is used to mechanically displace the switch contact (30). An RF gap area (25) located within the cavity (250) is totally segregated from the gaps (71) between the interdigitated metal electrodes (70). The membrane is electrostatically displaced in two opposing directions, thereby aiding to activate and deactivate the switch. The micro-electromechanical switch includes: a cavity (250); at least one conductive path (20) integral to a first surface bordering the cavity; a flexible membrane (60) parallel to the first surface bordering the cavity (250), the flexible membrane (60) having a plurality of actuating electrodes (70); and a plunger (40) attached to the flexible membrane (60) in a direction away from the actuating electrodes (70), the plunger (40) having a conductive surface that makes electric contact with the conductive paths, opening and closing the switch.

摘要: A method and structure that provides a battery within an integrated circuit for providing voltage to low-current electronic devices that exist within the integrated circuit. The method includes Front-End-Of-Line (FEOL) processing for generating a layer of electronic devices on a semiconductor wafer, followed by Back-End-Of-Line (BEOL) integration for wires connecting the electronic devices together to form completed electrical circuits of the integrated circuit. The BEOL integration includes forming a multilayered structure of wiring levels on the layer of electronic devices. Each wiring level includes conductive metallization (e.g., metal-plated vias, conductive wiring lines, etc.) embedded in insulative material. The battery is formed during BEOL integration within one or more wiring levels, and the conductive metallization conductively couples positive and negative terminals of the battery to the electronic devices. The battery may have several different topologies relative to the structural and geometrical relationships among the battery electrodes and electrolyte. Multiple batteries may be formed within one or more wiring levels, and may be conductively coupled to the electronic devices. The multiple batteries may be connected in series or in parallel.

摘要: Inductor losses to a semiconducting substrate are eliminated in an IC structure by etching a well into the substrate down to the insulating layer coating the substrate and fabricating a grounded Faraday shield in the shape of elongated segments in the bottom of the well. The well lies directly below the inductor and is optionally filled with cured low-k organic dielectric or air.

摘要: A means for fabrication of solenoidal inductors integrated in a semiconductor chip is provided. The solenoidal coil is partially embedded in a deep well etched into the chip substrate. The non-embedded part of the coil is fabricated as part of the BEOL metallization layers. This allows for a large cross-sectional area of the solenoid turns, thus reducing the turn-to-turn capacitive coupling. Because the solenoidal coils of this invention have a large diameter cross-section, the coil can be made with a large inductance value and yet occupy a small area of the chip. The fabrication process includes etching of a deep cavity in the substrate after all the FEOL steps are completed; lining said cavity with a dielectric followed by fabrication of the part of the coil that will be embedded by deposition of a conductive material metal through a mask; deposition of dielectric and planarization of same by CMP. After planarization the fabrication of the remaining part of the solenoidal coil is fabricated as part of the metallization in the BEOL (i.e. as line/vias of the BEOL). To further increase the cross section of the solenoidal coil part of it may be built by electrodeposition through a mask on top of the BEOL layers.
