IPC: H01L29/78
Filed: 1986-11-28
Abstract: PURPOSE:To form an LDD-MOS transistor having stable, reproducible, and uniform characteristics by carrying out an ion implantation with a high fusing point silicon compound layer as a mask before or after performing an oxidation process, thereby forming a region having highly concentrated impurities. CONSTITUTION:When a gap is developed in the interface, that is, a contact part between a compound layer 15 formed at a side wall part of a silicon gate electrode 13 and a gate oxide film 12, an oxide film 16 is formed in the interface between the compound layer 15 and the gate oxide film 12. After that or previously, a region 17 having highly concentrated impurities, that is source and drain regions 17s and 17d having the highly concentrated impurities are formed by carrying out an ion implantation of highly concentrated n-type impurities with a high fusing point silicon compound layer 15 as a mask and an anneal treatment is performed. As a result, the source and drain regions 14s and 14d having lowered impurity concentrations are formed and outside of the above regions, the source and drain regions 17s and 17d having the highly concentrated impurities are formed. Thus, an unstable use of sidewalls due to an anisotropic etching treatment can be avoided and a transistor having stable, reproducible, and uniform characteristics is formed.

Title: Discharging gas from dust pit
Inventor: NAGASEKI MICHIO
IPC: B01D46/42
Filed: 1989-10-31
Abstract: PURPOSE:To remove dusts in an air filter without stopping the gas discharge from a dust pit and prevent the increase in pressure loss in an air filter. CONSTITUTION:When the situation calls for dust removal, firstly a suction blower 10 is started to make negative the pressure of the inside of the system of a dust removal device and dusts are drawn from the suction section 6 that is provided near the air suction face of an air filter 2. The dusts are sent with the air in the vicinity to a dust collector 7. And in a cyclone 8 relatively large dusts are removed, and next dusts of fine particles are removed by a bag filter 9 and they are discharged into a dust pit. Since the removal of dusts in the air filter 2 can not be effected at one time on the whole area, the suction section 6 is moved and only dusts on a small section of the face of the air filter 2 are drawn at one time and it is continued. With this arrangement the pressure loss in the air filter can be maintained in a desirable range, and, therefore, the incinerator is not stopped for removing the dusts in the air filter and the working efficiency of the incinerator is raised.
