Abstract: PURPOSE:To raise the aligning accuracy of a submicron pattern without irregularity in a wafer face by patterning an insulating film with a mask material patterned by the mask material that has a film formed on its side wall. CONSTITUTION:After a P-type layer 22 is formed on an N-type silicon substrate 21, mask materials 25, 26 are formed through a silicon oxide film 23 and a silicon nitride film 24. With a resist 27 as a mask the material 26 is selectively etched to open in a width L1. After the resist 27 is separated, a film 30 is deposited. The film 30 is etched to obtain a hole 31 of width L2 by allowing it to remain on the side walls of the material 26. Then, with the material 26 and the remaining film 30 as masks the material 25 is etched. After the material 26 and the film 30 then remain, the films 24, 23 are selectively removed by etching with the material 25 as a mask. The material 25 is further removed, P<+> type regions 32, 33a, 33b are formed on the layer 22, and leading wirings 34, 35 are formed to manufacture a transistor.

Title: Dry etching
Inventor: YANAGIDA TOSHIHARU
IPC: H01L21/3065
Filed: 1990-11-02
Abstract: PURPOSE:To increase a productivity, controllability, stability, etc., of etching of a silicon oxide material layer by performing etching, setting such conditions that the etching speed of an organic polymer film might be equal to that of the silicon oxide material layer. CONSTITUTION:When isostatic etching is performed for a resist film 5 and layer-to-layer insulated film 4 using C2F3 gas, the layer-to-layer insulated film 4 is made nearly flat. If all the specified etching conditions are met, the etching speed of the resist 5 is made equal to that of the layer-to-layer insulated film 4 simply by optimizing the temperature of an etched substrate within a practical temperature range. In the etching, such an etching gas is used as may contain only one kind of gas which generates a principal etching species and such etching conditions are set that the etching speed of an organic polymer film may be made equal to that of a silicon oxide material layer by controlling the temperature of the etched substrate. Consequently, a rapid etchback is performed especially for the silicon oxide material layer with good controllability.

Title: Diffuser pipe for fluidized bed device
Inventor: IDEI YASUMASA
IPC: F23G5/30
Filed: 1990-11-02
Abstract: PURPOSE:To prevent adhesion of cinders or the like and contrive a long-time operation, by providing a gas outlet in the vicinity of a top part of a gas inlet pipe part fitted to a diffuser plate, and arranging a gas-reversing tube above the gas outlet to form a diffuser pipe. CONSTITUTION:An exhaust gas from fluidized combustion of coal in a fluidized combustion chamber 13, together with ashes and portions of unburned components, flows into each gas inlet pipe 31 at a diffuser plate 30. The exhaust gas together with the ashes and unburned components passes through a top part of the pipe 31 into a gas-reversing tube 35a on the upper side, is then reversed by colliding against the lower surface of a ceiling plate 35c of the tube 35a, and flows downward along the inner surface of a sleeve 35d, to be exhausted through a gas outlet 37 into a desulfurizing chamber 19. The gas outlet 37 has a sufficient large area, which ensures exhaust at a low velocity and prevents adhesion of ashes or the like to the outlet part. The gas fluidizes a fluid medium (coal ash) above the gas outlet 37 of the diffuser pipe 35, thereby forming a desulfurizing fluidized bed S, in which the unburned components such as unburned carbon are burned, and the exhaust gas is desulfurized.

Title: Method for driving solid-state image sensing element
Inventor: YAJI YUKIO
IPC: H04N5/3722
Filed: 1988-11-22
Abstract: PURPOSE:To realize exposure control without feeling of physical disorder in comparison with shutter operation by performing reading operation of electric charge into vertical registers and clearing operation of electric charge in an optoelectronic transducer element by a plurality of times. CONSTITUTION:Vertical transfer registers 8 in an image sensing part are operated from T0 to T1 as phiV1 and phiV2 with a frame interline type solidstate image sensing element. Then, the registers are stopped. Thereafter, electric charges which are read out by a plurality of times by pulses of phiR0 are sequentially added between the vertical transfer registers. When the sequentially added electric charges can be controlled within a period corresponding to the interval between the applied pulses phiR0, the amount of the control can directly determine the amount of exposure. For example, when the pulse interval is five lines (c), the pulses phiCR are applied, and the electric charge which is accumulated after the pulses phiR0 are applied is cleared. The control is performed in this way. The effective exposing time is made to be a period from T4 to T5. The pulse applying timing of phiCR is moved back and forth. Thus the amount of the exposure can be freely adjusted.
