Abstract: PURPOSE:To avoid conductor discontinuity and enhance reliability such as electromigration resistance by a method wherein, after a contact hole is formed, a semiconductor thin film or a thin film containing metal is formed on the side surface of the contact hole and then the contact hole is selectively filled with metal. CONSTITUTION:After a high concentration diffused layer 2 is formed in a semi conductor Si substrate 1, an insulating film 3 is formed and a contact hole 4 is drilled in the insulating film 3 to expose the diffused layer 2. Then a 2nd insulating film 5 of thin thickness is deposited over the whole surface and succes sively a thin polycrystalline Si film 6 is formed. The polycrystalline silicon film 6 on the bottom surface of the contact hole 4 and on the flat planes of the 1st and 2nd insulating films is removed. The 2nd insulating film on the bottom surface of the contact hole 4 is etched to expose the diffused layer 2. Gas composed of WF6 diluted by Ar is made to react with the polycrystalline Si film 6 and the Si diffused layer 2 to deposit a W film 7. Then WF6 is made to react with gas containing H2 and W 7 is made to grow by utilizing hydrogen reduction reaction.

Abstract: PURPOSE:To eliminate the case in which the occurrence of an abnormality is overlooked even if a protective device automatically returns to the original state by providing a memory unit which stores action signals of the protective device and displaying the actions of the protective device to peripheral units by the outputs of the memory. CONSTITUTION:When an abnormality signal from a protective device actuation detector 33 is inputted to a signal collecting and memorizing device 21, it is stored in a memory 50, and its output is sent to a CPU 1 through transmissions I/F 46 and 6, and it is displayed as an abnormality on a CRT 2. When a service is started on this information, 'maintenance' is displayed on a CRT 2 with a maintenance switch 49 pressed down. On the other hand 'abnormality' is displayed on the CRT 2 by the output from the memory 50. This abnormality display is continued to be displayed until the maintenance switch 49 is turned OFF so that the abnormality display is continued even if the protective device returns automatically to the original state. With this arrangement the occurrence of an abnormality is never overlooked and it can be displayed on CRT during maintenance service.

Abstract: PURPOSE:To lower the resistance of a gate electrode, gate length thereof is shortened, by applying a resist onto a substrate to which the heat-resistant gate electrode is formed, exposing a gate electrode section and plating the gate electrode section. CONSTITUTION:An N<+> layer is shaped onto the whole surface of a semi- insulating GaAs substrate 11 while using a heat-resistant gate electrode 14 formed onto the substrate as a mask. A Ti/Au film 15 is shaped onto the whole surface of the substrate 11. When a resist 16 is applied rotatably, the resist film on the electrode 14 as a projecting section is thinned. The resist 16 is removed so that the film 15 in the upper section of the electrode 14 is exposed. An Au layer 17 is shaped only on an exposed section on the electrode 14 through the plating of Au as a low resistance material while the resist 16 is employed as a mask and the film 15 as an electrode. The resist 16 is removed. Accordingly, gate resistance can be lowered, thus improving high-frequency characteristics.

Filed: 1990-04-03
Abstract: PURPOSE:To prepare a resin compsn. melt moldable and excellent in gas barrier and mechanical properties by compounding a polyamide resin with a specific polyvinyl alcohol copolymer resin. CONSTITUTION:A resin compsn. is prepd. by compounding 100 pts.wt. polyamide resin with at least 5 pts.wt. polyvinyl alcohol copolymer resin which contains 1-50wt.% ethylene and is obtd. by copolymerizing vinyl acetate with ethylene in the presence of a polyvinyl alcohol in an amt. of at least 10wt.% based on the sum of the polyvinyl alcohol and vinyl acetate. An example of the polyamide resin is a polycondensate of a lactam, an epsilon-amino acid, a dicarboxylic acid, and a diamine. The copolymer resin with an ethylene content higher than 50wt.% shows a poor compatibility with the polyamide resin and imparts the compsn. poor gas barrier properties; the ethylene content lower than 1wt.% imparts the compsn. a poor melt moldability.
