Title: Cu alloy extra fine wire for bonding wire of semiconductor
Inventor: HOSODA NAOYUKI
IPC: C22C9/00
Filed: 1987-03-27
Abstract: PURPOSE:To prevent the damage to the surface part of a semiconductor chip and to improve the stability of looping by incorporating, as the alloy component, specific ratio of B into the titled wire and regulating the content of S as the impurities to the specific value or below, thereby decreasing the hardness and work hardening of the wire. CONSTITUTION:The copper alloy for the extra fine wire contg. 1-100ppm B, contg. at need one or more kinds among 1-10ppm rare earth elements of Be, Ca and Ge and consisting of the balance Cu with inevitable impurities (where the content of S as the impurities is regulated to <=0.5ppm) is prepd. The work hardening accompanied by the deformation of the ball part formed on the tip part of each wire is remarkably suppressed and the hardness of the ball part is as well lowered by the decrease of S content and the addition of B in this manner. The semiconductor chip and the coat on the surface are therefore hardly subjected to damage and the generation of an edge shot to the semiconductor chip is remarkably suppressed by the stabilization of the looping. The looping is furthermore stabilized by the addition of the rare earth elements, Be, etc., to the alloy.

Title: Amorphous silicon carbide series semiconductor
Inventor: MORI MASAAKI
IPC: H01L21/205
Filed: 1983-04-26
Abstract: PURPOSE:To reduce the density of localized state generated by mixing carbon atoms to silicon by doping the titled semiconductor of amorphous structure with the atom of a kind or more of Sn, Ge and Pb. CONSTITUTION:The irregularity of amorphousness produced by the strong bond of carbon and silicon is alleviated by doping said semiconductor with the atom of a kind or more of Sn, Ge and Pb, the same four-group as silicon, whose radius of covent bond is larger than that of the carbon atom. Here, the doping amount of the doping atom is needed in the amount optimum to reduce said density. For example, since the density of localized level of a-SiC due to dangling bond is 10<17>-10<19> spins/ev.cc, the doping atoms are sufficient at 10<14>- 10<17>/cm<2>. It is at most 0.1% or less at the ratio of atomic numbers, and preferably 0.01-0.001%.

Abstract: PURPOSE:To reduce the circuit scale and reduce the erroneous operation due to noise, as for a sensor circuit. CONSTITUTION:A sensor circuit is used for a sensor device which is installed at a gateway and carries out the specific information operation according to the passing of persons. When an infrared ray sensor 1a senses the approach of a person, a sensor part 1 generates an output. Receiving the output of the sensor part 1, an oscillation part 2 generates clock pulses. Receiving the output of the sensor part 1, a processing part 3 starts the generation of the special output for carrying out the information operation, and counts the starting-up of clock pulse, and when the count value reaches a prescribed value, output is suspended by the starting-down of the clock pulse. Accordingly, the circuit scale is reduced by using the clock pulse in one system, and the influence of noise can be reduced.

Title: Coated floor and construction method thereof
Inventor: ASAKURA TAKAHIRO
IPC: C09D167/00
Filed: 1999-03-19
Abstract: PROBLEM TO BE SOLVED: To follow expandability of a substrate by applying urethane resin as finish coating via a primer and undercoating after grinding of a concrete substrate. SOLUTION: After the surface of placed concrete is smoothed being sanded with a polisher, polished material is sucked and eliminated by a cleaner for surface treatment. An epoxy resin solvent is applied as a primer with a roller brush, and epoxy resin is applied as an undercoat with a trowel. After undercoating is executed, urethane resin with zeolite added as an adsorbent is applied as coating material to the surface of the undercoat by troweling work to finish a coated floor. The adsorbent is mixed to avoid a foaming phenomenon under high temperature and high humidity, and diatom earth, activated charcoal or activated clay can be used instead of zeolite. Substrate expansion is therefore followed well to prevent the formation of a crack.
