  • Method of manufacturing by etching a semiconductor substrate horizontally without creating a vertical face
    Patent number: 7947576
    Abstract: An aspect of the invention provides a method of manufacturing a method of manufacturing a semiconductor element comprises the steps of: growing epitaxially a semiconductor layer on top of a semiconductor substrate; forming a patterned portion of the grown semiconductor layer by forming a pattern by a patterning process on top of the grown semiconductor layer; removing a portion of the semiconductor layer other than the patterned portion by a first etching method with a first etchant; and immersing a resultant from the first etching method in a second etchant that etches only the semiconductor substrate by a second etching method thereby removing the substrate from the semiconductor layer.

  • Solar cell and solar cell module
    Patent number: 7947893
    Abstract: A solar cell includes: a photoelectric conversion part having a concave and convex profile in a light receiving surface thereof; and a protective layer 10 which is provided to cover the concave and convex profile, and which includes particles therein. In a cross section, in parallel with an incident direction of light, of the protective layer 10, the number of the particles 11 contained in a second region is smaller than the number of particles 11 contained in a first region. The first region is centered at a concave portion of the concave and convex profile, and has a unit length, while the second region is centered at a convex portion of the concave and convex profile, and has the unit length.

  • Piezoelectric resonator plate, and piezoelectric resonator device
    Patent number: 7948156
    Abstract: A piezoelectric resonator device comprises a piezoelectric resonator plate, a base for holding the piezoelectric resonator plate, a lid for hermetically enclosing the piezoelectric resonator plate held on the base, and a support member made of a brittle material for reducing external stress to the piezoelectric resonator plate. The piezoelectric resonator plate is held on the base via a support member. In this case, the base, the piezoelectric resonator plate, and the support member are bonded with each other using a base bonding member and a piezoelectric resonator plate bonding member (connection bumps) by FCB using ultrasonic waves. The base is electrically and mechanically bonded with the support member via the base bonding member in a plurality of areas of the support member using ultrasonic waves.

  • Illumination device and projection display device
    Patent number: 7946711
    Abstract: An illumination device includes a light source part for emitting light with an intensity distribution approximately uniform in a first direction and a fly-eye lens into which the light is entered. The light source part and the fly-eye lens are arranged such that the first direction is inclined with respect to vertical and horizontal directions of arrangement of lens cells in the fly-eye lens. Since illumination light is entered into the fly-eye lens in a state of inclining with respect to the fly-eye lens, the number of superimposition patterns on the fly-eye lens is increased and illuminance non-uniformity in illumination light is suppressed.

  • Radio communication system, radio communication method and base station
    Patent number: 7937087
    Abstract: A radio communication system includes: a serving cell (for example, cell A functional unit 120) configured to transmit, to a radio terminal 10, an AG for directly specifying an uplink user data transmission rate and an RG for relatively specifying the uplink user data transmission rate; and a non-serving cell (for example, cell B functional unit 130) configured to transmit the RG to the radio terminal without transmitting the AG. The non-serving cell includes an instruction unit 132 configured to instruct the serving cell to decrease the uplink user data transmission rate, when a reception power of uplink user data received from the radio terminal 10 exceeds a predetermined interference threshold.
