Title: Formation method of pattern
Inventor: IKUTSU HIDEO
IPC: H01L21/302
Filed: 1990-04-16
Abstract: PURPOSE:To form a pattern of an insulating film having a hole whose shape is optimum for burying a metal interconnection by a method wherein the insulating film is constituted of a film which includes a silicon oxide film and a silicon nitride film. CONSTITUTION:A silicon oxide film 8 is formed on a substrate or an interconnection 1; after that, a silicon nitride film 9 is formed; in addition, a glass film 10 which contains phosphorus or boron is formed; an insulating film 2' is formed. Then, the film 10 is etched to the halfway part of its film thickness. After that, the remaining film 10 is wet-etched by buffered hydrofluoric acid. Since the film 9 is not dissolved by the hydrofluoric acid at this time, the dissolution of the film 10 progresses only in the transverse direction and is stopped at the film 9 in the depth direction. Lastly, the remaining films 9, 8 are dry-etched; a step-shaped taper connecting hole 11 is formed. Consequently, the opening width of the connecting hole can be prescribed only by the time of a wet etching operation, the substrate is not etched excessively and the connecting shape can be formed in an optimum shape.

Abstract: PURPOSE: To prepare a powder for a fresh vegetable juice utilizing an enzyme, by vacuum drying a fresh vegetable in a ball mill at 5°C, and powdering the dried vegetable.  
     CONSTITUTION: A fresh vegetable washed with water is introduced from introductory ports 14 and 15 into a ball mill kept at 5°C, and a vacuum valve 8 is opened to operate a vacuum pump 7. The inner cylinder 3 is then rotated by a motor 17, and the fresh vegetable is vacuum dried while being crushed with balls 4. At a given moisture content, the constant rate drying is stopped, and the decreasing (falling) rate drying is carried out to dehydrate only the water in cells. When the vacuum is saturated with moisture, only the air expelling is restarted. If the moisture content is reduced, the air expelling is stopped to permit the natural transpiration. During this time, the intermittent vacuum drying and air expelling  steps are repeated, and the vacuum valve 8 is closed at a moisture content of 10%  or less to start the pulverizing of the vegetable with the balls 4. After the completion of the pulverization, dry air is intro duced from an outside air dehumidifying  apparatus 13 into the inner cylinder 3 to equilibrate the internal pressure with the  outside air pressure.
