Title: Manufacture of semiconductor device
Inventor: YODA SEIICHI
IPC: H01L29/78
Filed: 1987-03-18
Abstract: PURPOSE:To prevent dielectric breakdown, by leaving a resist film like an umbrella on a gate electrode, depositing an insulation film on the whole surface, and sputtering vertically the insulation film so that it is adhered on the side walls of the gate electrode under the umbrella-like resist film. CONSTITUTION:A gate electrode film 23 is deposited on a semiconductor substrate 21 with a gate insulation film 22 interposed therebetween and is patterned by using a resist film 24 as a mask. The film 23 is further overetched until it provides a gate electrode 23 covered with the resist film 24 which is projected from the side walls of the electrode 23 like an umbrella. Subsequently, an insulation film 26 is deposited on the semiconductor substrate 21 and on the resist film 24, and is sputtered vertically so that the insulation film 26 is adhered on the side walls of the gate electrode under the umbrella-like resist film. After the resist film 24 is removed, an insulation film is again deposited on the whole surface. Thus, the side wall insulation film can be provided by sputtering the insulation film 26 vertically so as to adhere on the side walls of the gate electrode 23 under the umbrella-like resist film. The resulting side wall insulation film can be formed uniformly on the periphery of the electrode and is hardly subjected to dielectric breakdown.

Abstract: PURPOSE: To extend an interval of backwashing operation by a method wherein air is blown from a bottom part of a downwardly flowing type filter tank and air raising upwardly is collected by an air cup and introduced into an air lift pipe to prevent raising of filtering resistance.  
     CONSTITUTION: Raw water is supplied from a supply port 5 and subjected to filtering treatment by filter layers 7, 8, 9 and discharged from a discharge port 6. In parallel therewith, pressurized air is injected into the filter layer 7 from an air supply pipe 3 and raised as air bubbles and a part thereof is diffused into the air from a liquid surface 10. Other part of said air bubbles is caught by an air cup 12 and, thereafter, introduced into an air lift pipe 11 from an opening part 13 and raised as air bubbles. Along therewith, water and sand are sucked up from a lower end of the air lift pipe 11 and dropped from an upper end of said pipe 11 to an outer side to be recirculated. Thereby, suspended substances are accumulated only to the upper part of the filter layer 7 to prevent rapid rising of filtering resistance and can be distributed over the total sand of recirculated part in a similar concn.
