Abstract: A bonding apparatus includes a bonding arm which is swayable about an axis, a horn which is fixed at the end of the bonding arm to perform ultrasonic bonding, a tool fixed on the horn, and a motor on the bonding arm at the opposite end to the horn. The bonding head both moves and bonds an electronic element.

Abstract: To remove the turbulence affecting the positioning control of a bonding head along the Z axis when a stage is moved in the XY direction, and to exercise accurate wire loop control, a feed forward compensator is provided for a control unit. The feed forward compensator calculates a reaction force, which is applied to a bonding head due to the acceleration generated during horizontal movement along the XY axes, based on the distance between the center of a rotary shaft and the center of gravity of the bonding arm, the mass of the bonding arm, and the acceleration generated when the XY stage is moved along the XY axes. The obtained reaction force is transmitted as a feed forward value to a controller, in order to offset the reaction force.

Abstract: An electron-emitting electrode for discharge lamps etc. uses an electron-emitting material which contains a first metal component selected from Ba, Sr and Ca and a second metal component selected from Ta, Zr, Nb, Ti and Hf and also contains oxynitride perovskite. The electron-emitting material has restrained evaporation during electric discharge and a high resistance to ion sputtering.

Abstract: A polishing process monitoring apparatus of a semiconductor wafer is provided, which is capable of monitoring correctly the process independent of various factors affecting optical measurement, such as the configuration, material, and size of a layered structure on the wafer, and the geometric shapes of patterns and their arrangement for respective semiconductor chips.

Abstract: An electron-emitting material contains a first metal component selected from Ba, Sr and Ca and a second metal component selected from Ta, Zr, Nb, Ti and Hf and also contains oxynitride perovskite. The electron-emitting material has improved electron emission characteristics, restrained evaporation at elevated temperatures, and minimized consumption by ion sputtering. The electron-emitting material is prepared by firing a metal component-containing raw material disposed in proximity to carbon in a nitrogen gas-containing atmosphere to thereby create oxynitride perovskite.
