Title: Method for heat-treating silicon wafer and silicon wafer
Inventor: KOBAYASHI NORIHIRO
IPC: H01L21/322
Filed: 1998-03-13
Abstract: PROBLEM TO BE SOLVED: To provide a heat-treating method by which, particularly, the COP density and the occurrence of a micro defect which becomes the core of an oxidization-induced lamination defect can be reduced on the surface of a silicon wafer for heat-treating the silicon wafer in a reducing atmosphere by using a device which can quickly heat and cool the silicon wafer. SOLUTION: In a method for heat-treating silicon wafer, a silicon wafer is heat-treated in a reducing atmosphere by using a device which can quickly heat and cool the silicon wafer. During the course of the heat treatment, the silicon wafer is heat-treated for 1-60 seconds within a temperature range from 1,200 deg.C to a temperature equal to or lower than the melting point of silicon. It is preferable to form the reducing atmosphere to a 100% hydrogen atmosphere or a mixed hydrogen-argon atmosphere and to adjust the heat-treating time to 1-30 seconds.

IPC: H04Q3/545
Filed: 1985-04-19
Abstract: PURPOSE:To perform a copying operation having large quantity of data with a simple constitution while reducing the load of a software and a processor by providing two status registers and two transfer buffers in either side of a main memory. CONSTITUTION:For example, the external file memory controller 4a of copying origin determines the contents of a status register provided in the main memory 2b. If it is EMPTY vacant, for example, it sends the data from an external file memory 5a to the main memory 2b and then displays FULL enough after the specified blocks are transferred. An external file memory controller 4b to be copied determines the contents of the status register in the main memory 2b. If it is FULL, it sends the data from the main memory 2b to the external film memory controller 4b and then displays EMPTY after the specified blocks are transferred. With the two status registers and two buffers installed in the main memory 2b, high speed processing can be achieved while switching reading and writing.

Filed: 1997-04-01
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption and to prevent a noise by providing waveform forming devices forming a waveform of a hold-switching signal for each output circuit, connecting them in series, transferring this signal, and giving it to each output circuit. SOLUTION: A hold-switching signal CX is supplied from an outside of a chip, and amplified by a buffer consisting of inverters IN241 and IN242. Further, two stages of inverters IN240a and IN240b, IN239a and IN239b,..., IN1a and IN1b are arranged for each output circuits OC240-OC1, and all circuits are connected in series. As a hold-switching signal is amplified by an inverter train provided for each output circuits OC, a waveform in a stage at which the signal is inputted to each output circuit OC is formed, and an edge part is abrupt same as the signal CX. Therefore, a through current I (IN1) flowing in the inverter IN1 to which this signal CX is inputted is slight, and power consumption is reduced.

IPC: F16K27/06
Filed: 1984-04-26
Abstract: PURPOSE:To prevent leakage or storage of fluid by applying demolding agent on the outer face of a vented ball rotatable in the body to open/close the fluid path then injecting macromolecular substance into the gap between the outer face and the inner face of body and hardening. CONSTITUTION:After applying demolding agent onto the surface of a ball 2, macromolecular substance 8 is filled from a seat section 7 into the gap between the inner face of the body 1 and the ball 2 and hardened. Macromolecular substance 8 is entirely filled except a space 10 produced through the locus of the open section of a through-hole of the ball 2. Epoxy resin mixed with hardener having low heat production, inorganic filler and flexible resin, as required, is employed as the macromolecular substance 8. Consequently even if fluid is confined in the through-hole 5 because of closure of the ball 2, leakage of fluid can be prevented because the opening of the through-hole 5 has been choked by macromolecular substance 8.
