Title: Production of colloidal silica
Inventor: KOJIMA YOSHIO
IPC: C01B33/151
Filed: 1990-07-09
Abstract: PURPOSE:To readily obtain colloidal silica not containing an alkali metal by adding an oxidizing agent and a mineral acid to a silicic acid aqueous solution free from the alkali metal and allowing the silica particles to grow in the presence of a basic organic compound, etc. CONSTITUTION:An alkali metal is removed from a silicic acid alkali metal salt aqueous solution having a silicic acid content of 1-10 wt.% and a pH of >=7. The treated solution is mixed with an oxidizing agent (hydrogen peroxide, hypochlorous acid or nitrous acid) to accelerate the polycondensation reaction of the silicic acid salt, and simultaneously mixed with a mineral acid (e.g. hydro chloric acid, nitric acid or hydrobromic acid) to stabilize a silicic acid aqueous solution. One part of the stabilized aqueous solution is aged and mixed with ammonia or a basic organic compound to prepare a basic silicic aqueous solu tion. The silicic acid aqueous solution is dropwisely mixed with the remaining silicic acid aqueous solution containing the oxidizing agent and a mineral acid.

Title: Manufacture of semiconductor device
Inventor: KURODA SHIGEKI
IPC: H01L21/76
Filed: 1992-07-07
Abstract: PURPOSE:To make it possible to remove bird's beak problems caused by a lateral progress of oxidation by etching isotropically a base oxide film and forming a silicon nitride film thereon and covering a side wall portion with the silicon nitride film. CONSTITUTION:When a base oxide film 12 in a device isolation area on a silicon substrate 11 is removed isotropically by etching with a photoresist 13 as a mask, the base oxide film 12 in the lower part of the photoresist at both ends is also removed. After the removal, a silicon nitride film 14 is formed and then the nitride film 14 in the device isolation area is removed. When a field oxide film 16 is formed, the end part of the silicon nitride film 14 covers the end part of the base silicon oxide film 12 entirely, which inhibits the oxidation in its lateral direction and prevents the field oxide film 16 from penetrating under the silicon nitride film 14. This construction makes it possible to form an excellent device isolation area without any bird's beak and miniaturize the devices.

Title: Probe for flaw detection of hot material
Inventor: MIZUNO MASASHI
IPC: G01N25/72
Filed: 1983-09-28
Abstract: PURPOSE:To maintain a probe for flaw detection of a hot material at the service limit temp. or below with said probe by disposing a reflecting plate in an aperture facing a hot material and providing an intake port for passing air on the preceding side in the turning direction of the probe. CONSTITUTION:A hot material 1 is transferred in an axial direction and at the same time a probe 2 turns around said material to detect the flaw thereof. Many of the heat rays radiated from the material 1 to be inspected are reflected by the reflecting surface 8a of a reflecting plate 8 and do not arrive at a probe body 5 so that the increase in temp. of the probe body is prevented. As the probe turns, air flows into a case 3 through an air intake port 11, passes around the body 5 and is discharged through a discharge port 12, by which the temp. increase of the probe body is suppressed. The temp. of the probe body 5 is thus maintained at the service limit temp. or below and if there is a flaw in the material 1, the magnetic flux of a coil 7 changes and the flaw is detected by eddy current flaw detection.
