    • A biaxially oriented polypropylene film which is excellent in heat resistance and long-term breakdown resistance at high temperature, little suffers from insulation defect, and has an advantage in that when pieces of the film are immersed in an insulating oil, the oil can well penetrate in between the pieces and the pieces are little swollen with the oil; and a capacitor made by using the film as the dielectric and excellent in heat resistance, breakdown resistance, corona resistance, long-term serviceability at high temperature, and current resistance. The film is a biaxially oriented polypropylene film characterized in that the isotacticity, isotactic pentad fraction and ash content are 98 to 99.5 %, 99 % or above and 30 ppm or below, respectively, and that the center-line average roughness of each surface is 0.01 to 0.4 mu m.

    • PURPOSE:To effectively clean the surface of solid silicon by irradiating the surface of solid silicon regulated to ground potential with the ions of rare gas generated from an electron cyclotron resonance cavity impressed with positive potential in a vacuum vessel introduced with rare gas. CONSTITUTION:Solid silicon 4 which has been contaminated by SiO2, surface segregation of the impurities and organic substance, etc., and has a form of single crystal, polycrystal and amorphous substance is arranged in a vacuum vessel 14 and rare gas such as He, Ar and Ne is introduced into the vacuum vessel 14. A magnetic field is generated with a magnet 10 provided to the outer periphery of an electron cyclotron resonance(ECR) cavity 9 which is partitioned from the vacuum vessel 14 by an insulating ring 3 and microwave is introduced into the cavity 9 through a waveguide 8 from a microwave power source 7 and the cavity 9 is impressed with bias voltage by a DC power source 12 and also solid silicon 4 is regulated to ground potential. The surface thereof is irradiated by the ion beam 11 of rare gas to remove oxide, the impurities and organic substance, etc., on the surface of solid silicon 4 and thereby this surface thereof is effectively cleaned.
