Filed: 1987-08-20
Abstract: PURPOSE:To prevent interference due to the collision of calls and the lowering of line efficiency from being generated, by performing all of the delivery of telegrams by a prescribed procedure under the control of a specific station when the specific station sends the telegram to plural stations. CONSTITUTION:Firstly, a seaside station (specific station) informs a station having the telegram to be transmitted by the unidirectional error character correcting mode and simultaneous call system of periodical print telegraph communication and a call frequency to plural ship stations. Next, corresponding ship stations are called station by station by an informed call frequency by an automatic re-sending request mode and selective call system, and the telegram is sent. when no response is obtained from the ship station, a call by a different frequency is performed sequentially. It is advisable to register the frequency of the ship station in advance to heighten call efficiency. By constituting a system in such way, it is possible to prevent simultaneous call to the seaside station by the ship stations receiving information of the presence of transmission telegrams in a large number of ships to be called from being performed, and to prevent the interference due to the collision of the calls and the error of a reception code from being generated.

Title: Manufacture of semiconductor device
Inventor: ASAO YOSHIAKI
IPC: H01L21/768
Filed: 1989-08-10
Abstract: PURPOSE:To enable formation of a fine contact with high reliability by carrying out ion implantation of impurity with a mask of an impurity injection blocking layer, by forming an impurity region, by removing it, and by oxidizing a substrate surface. CONSTITUTION:A P-type silicon substrate 10 is heat-oxidized to form an oxide film 11. A photoresist film is formed and patterned to make the photoresist 12 remain in a place wherein opening of a contact is planned. Ion implantation is performed for arsenic 75+ using the resist 12 as a mask to form an N<+> layer 13. Concentration at the region 14 near the surface of a silicon substrate below the resist 12 becomes lower than that of the N<+> layer 13. After the resist 12 and the oxide film 11 are removed, heat oxidation is performed for the substrate 10 in a water vapor atmosphere to form a silicon oxide film 15. Since impurity concentration of the N<+> layer 13 and the region 14 differs, oxidation velocity differs and a thick silicon oxide film is formed to that of higher concentration. A thin oxide film 16 is removed by RIE to open a contact hole 17. Ion implantation of arsenic 75+ is performed for the substrate 10 and an N<+> diffusion layer 18 is formed in the region 14.
