Patent JP-H0845903-A (JP)
Title: Plasma etching method
Inventor: KOTO NAOYUKI
IPC: H01L21/3065
Filed: 1994-07-27
Abstract: PURPOSE:To decrease the generation of particles and variation with time even in high density plasma by a method wherein discharge power and bias power are applied intermittently, and the above-mentioned powers are applied separately. CONSTITUTION:The application of discharge power into a treatment chamber and the application of bias power to the sample to be etched are conducted intermittently in such a manner that the discharge power and the bias power are not applied simultaneously. For example, the polycrystalline Si film formed on SiO2 is etched using a microwave etching device and RF of 800kHz is used for application of bias to the sample. The bias RF power and the discharge microwave power to be applied are ON/OFF modulated with the period of 100msec and the duty ratio of 50%, and only the difference of phase of DELTAphiis changed. At that time, when the grain diameter of the particles in gas phase is measured, the average value of grain diameter of the particles becomes the smallest with the has difference of DELTAphi=pi.

Filed: 1990-07-04
Abstract: PURPOSE:To suppress low frequency jitter by applying switching control to a band of a low pass filter in a phase synchronizing circuit periodically with a detection signal of pointer adjustment in a demultiplexer section. CONSTITUTION:Only a valid data is written in a buffer memory 2 by using a write clock signal whose period equivalent to a period of an invalid data is missing, and read by a read clock signal, and the read data and the read clock signal are transferred to a next stage processing circuit or the like.

The high- temperature waste heat heats the dry cells at high temperatures from the bottom surface of the incinerating floor 13 and returns to the flue 6 from a bypass flue 9. On the other hand, high-temperature waste gas taken in the upper stage 12 is adjusted of its flow-in amount by a gate 15 to carry out the incineration and a complete combustion of a combustible matters. Evaporated mercury enters and air cooling tower 16 together with the high-temperature waste heat gas to be subjected to primary cooling. Further, the evaporated mercury is cooled by a secondary cooler 17 and a tertiary cooler 18. The evaporated mercury cooled to the boiling point thereof is converted to a metal mercury or a compound mercury, which is collected to a mercury reservoir 27 and is recovered.

Abstract: PURPOSE:To simplify the construction of a location sensing mechanism by moving a plurality of wafer cassettes to a specific position, and by irradiating a beam for location sensing only onto a cassette in the position where wafer is set and removed and processing is performed. CONSTITUTION:A driving part AD for setting and removal of wafers, which is movable vertically and rotatable, is installed between a plurality of wafer cassettes WK (WK3, WK4) arranged symmetrically to above the below and to the right and left.

Title: Microflowmeter
Inventor: ICHIHARA TATSUYA
IPC: G01F1/68
Filed: 1982-10-07
Abstract: PURPOSE:To measure a flow rate, by measuring the electric power quantity that is consumed to heat up the area of a throttle part of a measuring part to keep a difference between said throttle part and a fluid temperature constant. CONSTITUTION:A fluid flows at a speed v1 through the area having no throttle part of a detector 7 made of a material used for a thermistor, etc., and the fluid temperature of this time point is defined as t1. Thus a heating current flows between heat terminals 5 and 6 to heat the throttle part of the detector 7 up to a surface temperature t2. Furthermore, the difference between temperatures t1 and t2 is kept constant. A throttle part is added to the detector 7 to accelerate the speed of the fluid to v2 from v1, and therefore the quantity of heat absorbed from the surface of the throttle part increases. This meter increases the speed of response and then the accuracy of measurement for a micro flow rate of the liquid. The quantity (EA) of heat absorbed from the throttle surface area is shown as EA=alambdagammav2(t2-t1), where (a) is the throttle surface area, lambda is the heat transmission coefficient and gamma is the specific gravity of the fluid. Then gammav2= KEA is satisfied as long as K=alambda/t2-t1 is satisfied. The weight and the flow rate are obtained from gammav2 as long as the dissipated heat quantity EA is obtained. This quantity EA can be obtained by measuring the electric power consumed for heating.
