Title: Manufacture of mis semiconductor device
Inventor: FUJISAWA TOMOTAKA
IPC: H01L29/78
Filed: 1996-02-29
Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing a MIS semiconductor device, wherein an electric field can be less concentrated in the vicinity of a drain region without increasing a source region in parasitic series resistance. SOLUTION: A PSG(phospho-silicate glass) film is formed only on the source region forming part of an active region of a P-type Si substrate 1, and then a gate oxide film 4 is formed. Then, an impurity-doped polycrystalline Si film is deposited on all the surface and then etched back, and a side wall spacer gate electrode 5 is formed on the side face of the PSG film. As ions are implanted low in concentration using the side wall spacer gate electrode 5 as a mask. After an interlayer installing film 9 is formed, the substrate 1 is subjected to a thermal treatment, whereby P contained in the PSG film is diffused into the active region high in concentration and implanted As ions are activated. By this setup, a source region 10 all high in impurity concertration is formed, and a drain region 11 provided with a low-impurity concentration part 11a is formed.

Title: Treatment of steel dust containing zinc produced in steel making for reutilizing as resources
Inventor: TAKEDA TAKASHI
IPC: C22B7/02
Filed: 1982-04-23
Abstract: PURPOSE:To recover Zn from steel making dust contg. zinc by separating Zn as vapor and condensing to liq. state by heating the dust with a heat medium to allow the zinc to react with a reducing material in an induction type electric furnace provided with a condenser in a cover part. CONSTITUTION:The pellets of steel making dust contg. Zn and a reducing agent such as powder coke are charged into a reaction retort 1 consisting of a low frequency induction furnace. A heat medium 6 such as iron scrap or the like in the retort is heated inductively by low-frequency induced electric powder, and the pellets of the steel making dust and the coke are allowed to react by the heat generated by heating so that ZnO in the pellets is reduced to Zn and is evaporated as the vapor of Zn. The vapor is condensed as liquid Zn 8 in a condenser 3 provided in a cover body 2 and zinc is thus recovered. The Fe component in the dust absorbs the C in the reducting agent and adds the same as molten cast iron in a heat medium 6, thereby increasing the heat capacity of the heat medium. The formed molten slag and a part of the increasing heat medium are removed by tilting the retort 1 and again the pellets and the reducing agent are added thereto so that the Zn is reduced and recovered.

The CPU12 detects that an interruption occurs from the sequence circuit 42 for power failure recovery, and the CPU12 executes a required software processing. At this time, if a recovery selecting switch 32 for automatic power failure is turned on, a turn-off signal is sent to a DC power source 10, and the power source 10 is turned off for a prescribed time. After the prescribed time, the circuit 42 sends a DC power source turn-on signal to the power source 10. The CPU12 generates an interruption at a constant time after turning-on of the power source 10 and confirms the turn- on of the switch 32 to restart the software processing automatically and operates a tape reader 20 to restart the work of an electric working machine 120.
