Abstract: PROBLEM TO BE SOLVED: To form groove element isolating regions composed of a random pattern so as to make them suited for highly integrated devices. SOLUTION: Grooves 101 are cut into a semiconductor wafer 10, and a silicon oxide film 21 and BPSG film 22 of specified concn. are deposited in the groove 101 and heat treated in the condition that voids in narrow grooves 101x are eliminated and surface step shape of the film 22 is not changed. After depositing a silicon oxide film 23 on the entire surface, the silicon oxide film 23, BPSG film 22, etc., are anisotropically etched, using a reverse mask, with leaving the buried layer 103a in the narrow grooves 101x and leveling protrusions in wide grooves 101z. A silicon oxide film 21 is deposited to make the entire wafer 10 flat. This makes it possible to uniformly fill the narrow and wide grooves at once and avoid contamination of gate insulation films with impurities of the film 22.

Abstract: PROBLEM TO BE SOLVED: To emit the light at the even brightness along the whole periphery of a lamp, regardless of the temperature distribution at the lamp periphery. SOLUTION: When a high-frequency current is let flow to a coil 2 from a high-frequency power source, a discharge tube 1 is lighted, and the water flow 100 around the discharge tube 1 is irradiated with the ultraviolet rays. Since the temperature of the upstream part TL of the discharge tube 1 is made lower than the other parts, in this case, the radiating amount of the ultraviolet- rays at the part TL of the discharge tube 1 is reduced, by leaving as it is, and the radiation of the ultraviolet-rays to the water flow 100 is mottled, but a capacitor C is connected to the coil part corresponding to the part TL, so as to make the current at this coil part different from the other parts, and the radiating amount of the ultraviolet-rays at this part is increased as the part of dropping the radiating amount of the ultraviolet-rays.  Consequently, an even radiating amount of the ultraviolet-rays can be obtained along the whole area in the longitudinal direction of the discharge tube 1, and the water flow 100 can be sterilized evenly.
