Title: Manufacture of semiconductor device
Inventor: TAKADA KAZUHIKO
IPC: H01L21/3205
Filed: 1989-12-20
Abstract: PURPOSE:To improve the flatness of a material to be etched by providing a process, in which impurities are introduced selectively to sections except the bottom of a recessed section, and a process in which the surface of the material to be etched is flattened. CONSTITUTION:When an inter-layer insulating layer 4 is formed, stepped sections 10A-10C are formed, and phosphorus ions are driven to the surface of the layer 4 from the four directions so as not to be implanted to the bottoms of recessed sections while turning a wafer at every 90 deg. under the conditions of implantation at an implantation angle theta=40 deg.. The impurity dosage is relatively reduced owing to shadowing effect by the protruding sections of the inter-layer insulating layer 4 on the bottoms of the recessed sections just under 10A-10C though the quantity of the impurity dosage is increased in the protruding sections and the side face sections of the recessed sections at that time. Consequently, the protruding sections and the side face members of the protruding sections can be etched selectively. Accordingly, the surface of the inter-layer insulating layer 4 is flattened easily.

Title: Light-water cooled reactor
Inventor: KATO KIYOSHI
IPC: G21C1/32
Filed: 1992-12-10
Abstract: PURPOSE:To stop a reactor to maintain safety by opening the conduit of liquid feed piping should pressure within a reactor pressure vessel be lowered. CONSTITUTION:A poison tank 25 disposed on the inside wall of an upper cover 24 retains a high-concentration boric acid solution P therein. If a primary cooling water pump 6 is operated during reactor operation, primary cooling water in a reactor core 2 is circulated through the pump 6 and a steam generator 3, etc. Heat exchange at the generator 3 allows generation of steam and cooling of the primary cooling water, and the discharge pressure of the pump 6 is delivered to a liquid feed control means 18 via a connecting pipe 23c. The means 18 blocks the conduit of equalizing piping 23a and then the boric acid solution P in liquid feed piping 23b is held in equilibrium and the boric acid solution P in the tank 25 is not allowed to flow into a reactor pressure vessel 1, and the reactor is operated in accordance with the amounts of primary cooling water and boric acid solution P in the vessel 1. When the pump 6 is stopped the means 18 opens the conduit 23a as the discharge pressure delivered thereto lowers, and the boric acid solution P is allowed to flow down into the vessel 1 by the difference in water head between the vessel 1 and the tank 25. Therefore, the concentration of boric acid increases and the reactor is stopped naturally.
