Title: Manufacture of semiconductor device
Inventor: TANAKA MAKOTO
IPC: H01L21/31
Filed: 1987-04-16
Abstract: PURPOSE:To prevent disconnection and shorting of a metallic wiring which is formed on a layer insulation film, by providing the layer insulation film with ion implantation to form a difference in the doping amount between a flat surface of the layer insulation and its inclined surface and next by utilizing an etching speed difference based on a concentration difference of the doping amount to flatten the surface by wet etching. CONSTITUTION:A layer insulation film 4 is formed on a MOS transistor whose source and drain are formed on a silicon substrate 2 by impurity diffusion. Next the whole surface is provided with ion implantation of phosphorus. Thereupon, the concentration of phosphorus implantation is high at a flat part of the layer insulation film 4 and low at an inclined surface of its recessed part. In succession, when the layer insulation film 4 is etched with a solution of hydrofluoric acid, the flat part of highly concentrated phosphorus implantation is etched in a great degree and the inclined part is etched in a small degree, and hence the layer insulation film 4 remains in the form of side walls of a gate electrode 8 and a field oxidizing film 10, and so the surface becomes smooth in its recessed and projected degrees. Thereafter, a PSG film 12 with a prescribed concentration of phosphorus is formed on the remaining layer insulation film 4a by a CVD method. This layer insulation film, whose surface is relaxed in its unevenness and flattened, can be formed accordingly.

Filed: 1990-04-09
Abstract: PURPOSE:To reduce as small as possible the secondary disaster due to the overflow of fire extinguishing water in a fire by hosing the fire extinguishing water mixed with high water absorbing property polymer or adding the polymer to hosed fire extinguishing water. CONSTITUTION:One end of a polymer supply hose 5 is connected on the way of the absorbing side hose 2 of a fire extinguishing water pump 1 and the other end is connected to a container 4 containing high water absorbing property polymer 3. Negative pressure produced by a suction force of the fire extinguishing water pump 1 in the absorbing side hose 2 causes the high water absorbing property polymer 3 in the container 4 to be automatically sucked into the hose 2, mixed with water 8 in the hose 2 and hosed through the discharge side hose 6. The polymer grains have few water attached therebetween and substantially no stick after the water suction. Further, since the hosed fire extinguishing water is rapidly absorbed after fire fighting to prevent apparatus and wall surfaces from the intrusion of the fire extinguishing water and easily separated and slid down from the wall surfaces or the like, the recovering operation is facilitated so that the fire extinguishing water can easily be recovered by a suction type large-scaled cleaner or the like.

Title: Production of transparent glass
Inventor: SUSA KENZOU
IPC: C03C13/04
Filed: 1980-07-15
Abstract: PURPOSE:A gel such as silica gel resulting from hydrolysis is formed into a rod or cylinder and made into sintered glass by heat treatment, thus preventing the development of cracks on the heat treatment and producing transparent glass in high yield. CONSTITUTION:A gel-forming solution such as a basic solution of Si(OCH3)4 in methanol and water is heated in a cylindrical vessel to cause hydrolysis to form a cylindrical gel. Then, the resultant cylindrical gel is sintered in an He gas in an electric furnace, e.g., at 1,200-1,300 deg.C. In case of sintering a cylindrical or rod gel, the time required to form the objective transparent glass becomes short by about one order compared with the case where a disk with the same thickness is sintered. The contraction of the treatment time accompanies the remarkable reduction in the crack formationand foaming during the treatment.
