Title: Microwave etching equipment
Inventor: OBUCHI KAZUTO
IPC: H01L21/3065
Filed: 1991-07-29
Abstract: PURPOSE:To prevent the temperature rise of a chamber, and improve the reproducibility and the stability of wafer etching, by connecting a suction duct with a wave introducing cylinder, taking in surrounding cool air through small holes, and making said air directly collide against the chamber. CONSTITUTION:When a wafer W mounted on a table 10 is irradiated with high density plasma which is generated with a microwave oscillator 7, guided through a waveguide 6 and turned into a high density state with an electromagnetic coil, the temperature of a chamber 3 is increased. Since the inside of the wave introducing cylinder 4 is kept at a negative pressure by the sucking action of a first suction duct 16, the air flows into the cylinder from a suction hole 18, and further flows into the cylinder through small holes 15. Said air flows along the outer surface of the chamber 3, and then discharged via the first suction duct 16. By the effect of this air flow, the chamber 3 is compulsorily cooled and kept at a nearly constant temperature. Hence the wafer W is stably etched with high reproducibility.

Abstract: PURPOSE:To make diffracted light from a light amplifier parallel with a light beam emitted from a light source by arranging a means deflecting the light beam in front of the light amplifier and previously deflecting the light beam projected to the light amplifier only by Bragg angle. CONSTITUTION:The light beam 2 emitted from the light source is divided into a transmitting light 2a and a diffracted light 2b which are separated only by Bragg angle thetaB with a first light amplifier 3 and the light beam (transmitting light 2a) whose intensity is controlled by changing the rate of the division is projected to a wedge-shaped division mirror 4 and a part of the light beam is reflected and guided to a light detector 5 and the rest transmits the mirror to be projected to a second light amplifier 6. The diffracted light 2d which is used for recording is deflected only by Bragg angle thetaB against the light beam projected to the second light amplifier 6. By setting the angle of the wedge of the wedge-shaped division mirror 4 as a proper angle, the light beam projected to the light amplifier 6 is previously deflected by the Bragg angle thetaB in an opposite direction to the light beam 2 emitted from the light source 1. Thus the proceeding direction of the diffracted light 2d and the light beam 2 emitted from the light source 1 can be made parallel.

Abstract: PURPOSE:To isolate a group of FETs by FET by arranging a conductive layer on an insulating film having the same thickness as that of a gate insulating film and by giving a potential to forbid forming of channels on a surface of an Si substrate under said insulating film. CONSTITUTION:Band shaped SiO2 12, polysilicon 13 laminated body and SiO2 14, polysilicon 15 laminated body are arranged in a lattice on a P type Si substrate 11.

By this constitution, an FET for isolation is formed with using the layer 13 as a gate among the crosswise rows of memory cells (FETs) of serial connection with using the layer 15 as a gate. If the layer 13 is constantly grounded, the FET of isolation keeps ''OFF'' condition and functions for isolation. This constitution enables isolation of groups within a small area without bad influence upon the characteristics of a group of FETs.

Title: Radiation thermometer
Inventor: SETO TOSHIKI
IPC: G01J5/10
Filed: 1984-10-11
Abstract: PURPOSE:To obtain the temperature of a body accurately by a radiation thermometer irrelevantly to the emissivity of the body by dividing infrared rays which are radiated by the body into plural wavelength components, and processing those respective components on the basis of specific radiation logic. CONSTITUTION:Infrared rays emitted by the body are passed through a dust protective filter 1 and guided to a rotary type variable optical fiber 8. The filter 8 separates the infrared rays into components of wavelength lambda and wave length lambda+DELTAlambda. Then, the light from the filter 8 is inputted to an amplifier 4 through an infrared lens 2 and an infrared detector 3 and inputted to an ampli fier 4. Signals of different wavelengths of the output of the amplifier 4 are inputted to sample holding circuits 10-10c. Radiation power and the variation rate to the wavelength of the radiation power are calculated, processed 11 on the basis of the radiation logic, and displayed 7. Thus, the variable optical filter and an arithmetic circuit are used to calculates the temperature of the body from radiation infrared rays from the body without knowing the emissivity of the body.

Filed: 1983-11-15
Abstract: PURPOSE:To achieve a shorter measuring time and a less measuring errors by calculating inversion frequency in the output state of a sampling gate composing a comparison means or the fixed circuit of sampling after the inversion. CONSTITUTION:As a command signal CS for the start of measurement is inputted from an input terminal CT, a control circuit CNT outputs an enable signal ES to an integration circuit INC and a counting circuit CUNT separately to release the initial state. At the same time, a trigger signal TS inputted from an input terminal TT is outputted to the integration circuit INC and the counting circuit CUNT separately. On the other hand, as the counting circuit CUNT is kept from counting the trigger signal TS as the output of a comparison circuit CMP is ''0''. In addition, the sampling signal is also outputted to the control circuit CNT to stop the output of the trigger signal TS inputted from the input terminal TT to the integration circuit INC and the counting circuit CUNT. At the same time, the control circuit CNT halts the generation of the enable signal ES.

Title: Liquid fuel combustor
Inventor: YOTSUYA NORIO
IPC: F23D11/10
Filed: 1987-08-27
Abstract: PURPOSE:To shorten the length of combustion flame so as to provide a compact combustion chamber and miniaturize a liquid fuel combustor by providing a combustion secondary air passage surrounding a mixing part and a combustion part, as well as secondary air holes above the combustion secondary air passage. CONSTITUTION:Part of combustion air enters into a mixing part 14 to be mixed with vaporized gas. It then is ejected from a flame hole plate 20 into the combustion chamber 24 wherein it is ignited and burnt. The rest of the combustion air is supplied to the burning flame through a combustion secondary air passage 16 out of secondary air holes 23. By inclining the combustion secondary air passage 16 from a position higher than the flame hole plate 20 toward the flame hole plate 20 which has secondary air holes 23 in its inclined surface 22, it becomes easier for the secondary air to be ejected toward and hit the burning flame, the combustion is promoted, thereby shortening the flame length and allowing a compact combustion chamber to be formed. Further, since the secondary air ejection holes 23 are arranged to surround the flame hole plate 20, the combustion secondary air can be supplied to the burning flame uniformly.
