Abstract: PURPOSE:To narrow the width of a gate electrode and to obtain a semiconductor device in which its gate series resistance can be reduced by providing thick oxide films at both sides of a gate oxide film, providing a conductive part under the oxide film, and providing a gate electrode also on the gate oxide film and the thick oxide film. CONSTITUTION:The surface of an epitaxial layer 1 is cleaned, an N<-> type region is ion implanted to form a nitride film 6 on the surface, and a nitride film 6 remains on a part formed with a gate by photocomposing. Then, it is oxidized in this state to form an oxide film 8. After the film 6 is further removed, an Si surface is etched, and a gate oxide film 4 is formed to a position where the N<-> type region 2 is separated to both sides. Then, a gate electrode 5 is formed by depositing or sputtering method. When the electrode 5 is so formed as to allow it to remain wider than the gate length by photocomposing, a semiconductor device is obtained.

Title: Etching of silicon oxide film
Inventor: NAGATA NOBUO
IPC: H01L21/306
Filed: 1986-05-14
Abstract: PURPOSE:To form an opening window on a silicon oxide film without using an ion implantation device by forming a thin film of rapid etching velocity on a silicon oxide film in order to perform photo-etching. CONSTITUTION:A silicon oxide coat forming solution is applied on a silicon oxide film 2 which is formed on a silicon substrate 1 by thermal oxidation and the substrate is rotated at high speed to form a coat 3 uniformly. This coat 3 is subjected to a heat treatment and is changed into a silicon oxide coat 3a. As a structure of the silicon oxide coat 3a is weaker than that of the silicon oxide film formed by thermal oxidation and its etching velocity is extremely fast, a photo-etching treatment 6 makes an etching cross-section a tapered form 5. This tapered angle depends on an ething velocity and a thickness of the layer 3a. The thickness of the silicon oxide coat 3a can be controlled by changing a concentration of the silicon oxide coat forming solution and the number of rotation of the substrate. Also, the etching velocity can be controlled by a temperature of the heat treatment.

Abstract: PURPOSE:To press a paper tape with an approximately fixed force even if the winding diameter of the paper tape is enlarged by providing a pressure reducing valve automatic operation means for automatically operating the pressure reducing valve according to a rising and falling angle of a tool rest. CONSTITUTION:As the diameter of a paper tape wound around a taking-up shaft 11 is enlarged, the rising and falling angle of the tool rest 4 is gradually enlarge. An automatic pressure reducing valve operating means is operated according to the rising and falling angle alpha of the tool rest 4 to automatically operate the pressure reducing valve 6 interlocked with an air cylinder 8 and gradually reduce the pressure in the air cylinder 8.
