Title: Manufacture of semiconductor device
Inventor: NAKAYAMA RIYOUZOU
IPC: H01L21/762
Filed: 1983-03-11
Abstract: PURPOSE:To prevent the generation of contamination on the surface of the recessed part of a field region by a method wherein a recessed part is formed on the field region without performing a lift-off process. CONSTITUTION:A thermal oxide film 22 is formed on the element forming region located on an Si substrate 21, and a recessed part 23 is formed on the field region using said film 22 as a mask. Then, the film 22 is removed, and an SiO2 film 25 in the thickness same as or more of the stepping of the recessed part is formed on the whole surface of the substrate. Subsequently, a positive type resist film 26 which is thinner than the stepping of the recessed part 23 is formed as a spacer film on the recessed part located on the surface of the film 25. Then, a mixed resist film 27 is applied as a fluid substance. Subsequently, an etching is performed on the whole surface. At this time, the condition of etching is established in such a manner that the etching speed of the film 25 will be faster than that of the film 26. As a result, when the etching is performed until the substrate surface of the element forming region is exposed, a structure wherein the film 25 is buried in the field region can be obtained. Subsequently, an element forming process is started, gate oxide films 281 and 282 are formed, and gate electrodes 291 and 292 are formed thereon.

Abstract: PURPOSE: To prevent cement from adhering to a screw shaft and blade of a cement conveyor, by coating a fluorine resin on the screw shaft and blade.  
     CONSTITUTION: The cement for slidifying radioactive waste of a nuclear power plant is transferred from a silo 1 to the conveyor 3 through a feeder 2. The cement is then introduced into a drum can 6 through a measuring hopper 4 and a feeder 5 so that the cement is solidified together with the radioactive waste. The screw shaft and blade of the conveyor are coated with the fluorine resin so that the cement is prevented from adhering to the screw shaft and blade. Therefore, it is not necessary for a workman to enter into radiactive region to effect maintenance and checking.

Abstract: PURPOSE:To further increase an electrical shielding effect between input output electrodes by providing a thin piece for preventing the adherence of a conductor plate between the conductor plate and a substrate so that a clearance can occur a little between the conductor plate and the substrate provided between the input output electrodes. CONSTITUTION:A thin piece 5 for preventing a conductor plate adherence is place on a substrate 1 and on it, a conductor plate 4 is provided. For this reason, the clearance of a dimension (a) occurs between the conductor plate 4 and the substrate 1. The conductor plate 4 is grounded. When a dimension O from a ground part C of the conductor plate 4 up to a clearance part 4B is set to a value smaller than the value to add the minimum value to consider the respective variances of a thickness (t) of the substrate 1 and a thickness (a) of the thin piece 5, the clearance part 4B is always brought into contact with the thin piece 5. Consequently, a clearance (a) is coincident to the thickness (a) of the thin piece 5. The thin piece 5 can be sufficiently made thinner regardless of a thickness (b) of the conductor plate 4. Consequently, the clearance part 4B can be sufficiently smaller, the thickness of the conductor plate 4 can be sufficiently thicker and a high shielding effect can be obtained.

The lid 7 is shut, and a carrier gas is supplied from a carrier gas inlet 1 into the chamber 6, and the particulates are dispersed. The carrier gas and dispersed particulates are led to a heating/gasifying chamber 2, and a cuvette 3 loaded with specimen in this chamber 2 is fed with current for running temperature, and thereby the specimen is evaporated. This micro-quantity of high temp. metal vapor condensates or makes reaction while the particulates in the heating/gasifying chamber 2 are used as nuclei to turn into inert particles and is transported to the inner chamber 4a of a plasma torch 4. Thereby the attaching amount of high temp. metal vapor to the inner wall of the heating/ gasifying chamber 2 and/or a connection tube 5 is reduced, and an ultra-micro quantity of metal element can be analyzed accurately.
