IPC: F04B49/06
Filed: 1996-09-03
Abstract: PROBLEM TO BE SOLVED: To perform predicted-estimated end pressure constant control excellent in cost performance and responsiveness and high in noise resistance by inputting an operating frequency signal of each pump and a pump identification signal, and transmitting an acceleration/deceleration signal to each pump so as to be conformed to the target pressure. SOLUTION: Pressure PS1 at a maximum water quantity specification point is inputted (S1). Small water quantity time pressure PS1 is then inputted (S2), and the maximum number of operating pumps SMax is inputted (S30). Maximum frequency Smax is inputted (S4), and small water quantity time frequency Smin is inputted (S5) to complete initialization. Operating frequency S is read (S6), and an estimated portion of flow change Qx is computed (S70). Operating reference pressure PS' is read (S8), and operating pressure PS is read (S9) to compare these pressure. In case of PS<PS', operating frequency of an inverter is heightened. In case of PS=PS', frequency is maintained in the present state. In case of PS>PS', frequency is lowered (S19).

Title: Semiconductor device and manufacture thereof
Inventor: INOUE AKIRA
IPC: H01L21/768
Filed: 1989-09-09
Abstract: PURPOSE:To reduce the parasitic capacity by a method wherein an insulating film near a circuit strongly affected by the parasitic capacity is removed to make a hole or a cavity near the circuit. CONSTITUTION:An insulating film 2 on the surface of the first circuit 4 is selectively removed by etching process etc., to make a vertical hole 3 on the surface of the first circuit 4. In this case, the insulating film may be removed in principle until the surface of the first circuit 4 is exposed to make the vertical hole 3, however, it is recommended that a thin film of the insulating film 2 shall be left in order to protect the surface of the first circuit 4. That is, since the surface of the first circuit 4 apt to be affected by any parasitic capacity is almost filled with the air having specific inductive capacity epsilon 1, the parasitic capacity can be reduced down to about 1/5 as compared with a semiconductor device entirely covered with an SiON insulating film.

Abstract: PURPOSE:To attain mass production of semiconductor wafers having scarcely any warp by a method wherein the wafer is irradiated by the energy beam of laser, etc. CONSTITUTION:A YAG laser beam having output of 0.1mJ/pulse or more is irradiated to the surface of a single crystal Si wafer 21 containing O2 by 1X10<17>/ cm<3> or more as impurities. The temperature of the surface is risen, supersaturated O2 is separated out in the neighborhood of the surface, and nuclei 22 of minute defects of about 10<16> piece/cm<3> are generated, while the nuclei 22 get away and are not generated at the surface. After then, when heat treatment is performed at 900 deg.C, for example, minute defects 22' are generated centering round the nuclei 22, a minute defect layer 24 of high density is formed, and a non defect layer 23 is obtained at the surface. Because only the surface can be heat-treated and in a short time owing to the use of the laser beam, the warp of the wafer and generation of a defect to the non defect layer according to the warp are not caused, and moreover an extremely thin non defect layer can be formed by controlling dispersion of supersaturated O2.
