Abstract: PURPOSE:To manufacture ceramic hollow spheres of the particle diameter as fine as a micron order having ceramic outer walls and excellent in heat resistance and pressure resistance, especially to obtain ceramic hollow spheres containing even such a metal that never or hardly makes metal alkoxide as the constitutional element. CONSTITUTION:A W/O emulsion is prepared by mixing an oil with a metal salt soln. obtd. by dissolving a water-soluble metal salt in water. Then, a metal alkoxide containing metal except for the metal element which constitutes the above metal salt is mixed to the emulsion to dissolve the metal alkoxide in the oil component of the emulsion. At the same time, sphere shells are produced in the interface of the water and oil and these shells consists of coprecipitate of the metal salt and the product of hydrolysis of the metal alkoxide with the water component in the emulsion. Further, the W/O emulsion containing the produced spheres is heated to the temp. at which the coprecipitate decomposes to produce a metal oxide, so that the oil and water are removed by decomposition or vaporization. Thus, ceramic hollow spheres comprising multiple oxides are obtd.

Abstract: PURPOSE:To form a good-quality film with simple constitution by disposing a substrate into a plasma chamber by a microwave and magnetic field and making the intensity distribution of the magnetic field low near the substrate and high in the position apart from the substrate. CONSTITUTION:The substrate 2 is disposed via a substrate holder 3 into the plasma chamber 1 in which plasma is induced by the microwave and magnetic field. A gas for CVD is then introduced into the chamber. The above-mentioned magnetic field is impressed approximately parallel with the substrate 2 by hole pieces 8 disposed on the outside of the plasma chamber 1. The intensity distribution thereof is made low near the substrate 2 and high in the position apart therefrom. The direction contact of the plasma with the substrate 2 is thereby obviated and the ions and free radicals are transported to the substrate 2, by which the dense and good-quality film is formed. The intensity of the magnetic field in the position apart from the substrate 2 in the above-mentioned method is preferably adjusted to the intensity at which electron cyclotron resonance arises or above at least at one point to efficiently generate the ions and free radicals.

Title: Structure of semiconductor element
Inventor: TOMINAGA YUKIHIRO
IPC: H01L29/40
Filed: 1992-03-04
Abstract: PURPOSE:To prevent adhesion of foreign matters due to the force of electrostatic attraction by leaving a polysilicon film for forming a gate electrode on a field oxide film and having a brush-scrubbing face as a conductor surface so as to eliminate generation of static electricity. CONSTITUTION:Field polysilicone 8'' is to be patterned so as to be electrically separated from a gate electrode 8' and its wiring part 8. When the surface of a thermal oxide film 9 is brush-scrubbed, much of static electricity is generated. However, since the oxide film 9 excepting the gate electrode 8' and its connection part is covered with field polysilicone 8'', no static electricity is generated so as to prevent sticking of dust. Further, the foundation of an intermediate insulating film 11 is covered with the wiring polysilicone 8 and the field polysilicone 8'. Accordingly, at the time of brush-scrubbing the surface of the intermediate insulating film 11, only the intermediate insulating film 11 is electrified and the film thickness of the film to be electrified is thinner than a prior example so that generation of electrostatic electricity can be suppressed low.
