IPC: H01L21/68
Filed: 1990-02-14
Abstract: PURPOSE:To provide a method of handling a semiconductor chip which can cope with the increase in size of the semiconductor chip by bringing the inner wall of the opening part of an air pincette into contact with two points on the ridge line of the upper surface of the corner of the semiconductor chip, the apex between the two points and two points on the ridge line of the lower surface, and supporting the chip. CONSTITUTION:An opening part 21 of an air pincette 20 is applied to the corner part of a semiconductor chip 10 at the side surface or the slightly upper slant part of the chip. The corner part 11 of the semiconductor chip 10 is contained in the opening part. Negative pressure is generated in the opening part 21 of the air pincette 20, and the semiconductor chip 10 is sucked. When the air pincette 20 is lifted, the semiconductor chip 10 is lifted up at the same time under the sucked state. The angular moment due to gravity is generated in the semiconductor chip 10. As a result, an apex part 16 at the intersection of the ridge lines of the upper surface is also brought into contact with the inner wall of a tip part 20 of the air pincette 20. Therefore, the five points 12, 13, 14, 15 and 16 on the ridge lines of the semiconductor chip 10 come into contact with the inner wall of the air pincette 20, and this state is maintaned.

Title: Organic chlorine compound sensor
Inventor: NOMOTO TAKESHI
IPC: G01N27/416
Filed: 1999-02-12
Abstract: PROBLEM TO BE SOLVED: To detect organic chlorine compounds in an environment in real time by holding an organic chlorine compound-decomposing system on a chlorine ion-selective electrode. SOLUTION: The organic chlorine compound-decomposing system used in the invention is appropriately selected in accordance with an organic chlorine compound to be detected. The organic chlorine compound-decomposing system is held on a chlorine ion-selective electrode in a manner not to be eliminated from the vicinity of the chlorine ion-selective electrode, which is achieved by fixing the decomposing systems to the surface of a chlorine electrode through chemical covalent bond, or by fixing the decomposing systems together by a hydrophilic polymer. The holding is achieved also by bringing the dissolving systems physically close to each other not depending on the chemical bond, for example, by sealing liquid components including the organic chlorine compound-decomposing systems in the vicinity of the chlorine ion-selective electrode by a hydrophobic organic thin film.

CONSTITUTION:Ga, As, and B2O3 are charged in a crucible for polycrystal synthesis which is similar in the form to a crystal growth crucible and slightly smaller, and melted to synthesize a GaAs polycrystalline substance having diameter (d) equivalent to the inner diameter of a small-sized crucible. The polycrystalline substance is charged in the crystal growth crucible having inner diameter D, a specified amt. of B2O3 is added, the mixture is heated under pressure, hence the B2O3 is firstly melted, and the GaAs polycrystal is covered with the molten B2O3. When the mixture is further heated, the GaAs polycrystal is also melted, and a molten B2O3 layer is formed on the surface of the GaAs melt. Since the surface of the polycrystal is always covered with the pressurized molten B2O3, escape of As is practically prevented. Since the charge amt. of the polycrystal can be increased while preventing the decomposition of the polycrystal, a high-quality GaAs single crystal can be produced with good reproducibility.
