PROBLEM TO BE SOLVED: To provide a better method for connection in an MEMS device. SOLUTION: The method comprises a step for forming a pair of first and second conductive strips (earthing wires 12a) separated from each other by a gap in a first conductive layer (bottom conductive layer 12); a step for forming a conductor (control voltage line 18) extending through the gap 22 in the first conductive layer; and a step for forming a conductive bridge 16e electrically connecting the first and second conductive strips to each other while being insulated from the conductor 18 in a second conductive layer (top conductive layer).

PROBLEM TO BE SOLVED: To provide a better method of forming a thin-film bulk acoustic resonator filter. SOLUTION: In the method of manufacturing a thin-film bulk acoustic resonator filer, a thin-film bulk acoustic resonator filter 10 includes a plurality of thin-film bulk acoustic resonators 38a to 38g series-connected and branched on the same film 35. The thin-film bulk acoustic resonators 38a to 38g are made of a single common lower conductive layer to have respective bottom electrodes of the thin-film bulk acoustic resonators. The single common conductive layer is provided to form respective upper electrodes of the thin-film bulk acoustic resonators 38a to 38g. A common piezoelectric thin-film layer, which may or may not be patterned, is formed as a thin film continuous as a single or not continuous. COPYRIGHT: (C)2010,JPO&INPIT

PROBLEM TO BE SOLVED: To perform energy harvesting in the platform of a portable computer. SOLUTION: A mass body, such as a mother board 102 already existing in the platform of the portable computer, is used, thereby to allow a device, for performing conversion into electric energy by using vibration energy to be added to the mass body, to be incorporated in the portable computer.

Abstract:
PROBLEM TO BE SOLVED: To provide a mobile computing apparatus having an ambient energy harvesting capability. SOLUTION: When the apparatus is manually operated, the apparatus converts a part of motion of a user's hand added to a controller of the apparatus into electrical energy. The energy powers the apparatus and is used to charge a battery of the apparatus. The apparatus has an electrical power storage apparatus provided in a housing, a display screen attached to the housing to display a plurality of user-interactive interfaces and a manually operable input controller which is capable of interacting with the interfaces and is coupled to an energy converter in the housing to charge the power storage apparatus when the apparatus is operated.

PROBLEM TO BE SOLVED: To provide a better method for forming a thin film bulk acoustic resonator filter. SOLUTION: The film bulk acoustic resonator filter 10 is formed of a plurality of interconnected series and shunt film bulk acoustic resonators 38 formed on the same membrane 35. Each of the film bulk acoustic resonator 38 is formed of one common lower conductive layer which is defined to form a bottom electrode 32 of the film bulk acoustic resonator 38. The one common conductive layer is defined to form a top electrode 36 of each of the film bulk acoustic resonator 38. One common piezoelectric film layer 34 which may or may not be not patterned forms one continuous or discontinuous film. COPYRIGHT: (C)2004,JPO
Abstract:
A microelectromechanical system (MEMS) that includes a first electro-thermal actuator, a second electro-thermal actuator and a beam having a first side and a second side. The first electro-thermal actuator applies a force to the first side of the beam as current passes through the first electro-thermal actuator and the second electro-thermal actuator applies a force to the second side of the beam as current passes through the second electro-thermal actuator.
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:
A micro-electromechanical (MEM) resonator is described that includes a substrate, a microbridge beam structure coupled to the substrate and at least one electrode disposed adjacent to the microbridge beam structure to induce vibration of the beam. The microbridge beam structure includes support sections and a beam formed between the support sections. The center region of the beam has a mass that is less than the mass of regions of the beam adjacent to the support sections.
Abstract:
An apparatus and method of fabricating a through-wafer via. A first mask is formed over a first side of a first semiconductor die to define a first via area. A deep recess is etched through the first semiconductor die in the first via area and a blanket metal layer is formed over the first side including the deep recess. The blanket metal layer is removed from an outer surface of the first side of the first semiconductor die while retaining a portion of the blanket metal layer within the deep recess.
