Title: Plasma etching method for silicon-oxide based insulating film
Inventor: FUKAZAWA MASANAGA
IPC: H01L21/302
Filed: 1997-09-25
Abstract: PROBLEM TO BE SOLVED: To provide a plasma etching method which can prevent the occurrence of a bowing shape, the defective removal in a connecting hole, etching stop and the like when minute patterning, e.g. patterning of the connecting hole and the like having the minute opening diameter, is performed on a silicon-oxide based film. SOLUTION: An etching gas including at least SiF4 is used. At the same time, a sidewall protecting film 11 containing Si or containing Si-C bonding is thinly formed at the side wall of a connecting hole 9 under patterning, and plasma etching is performed during the formation. In addition to the connecting hole, the line and space pattern such as an off-set insulating film on a gate electrode can be used. A side-wall protecting film 11 including Si or Si-C bonding has the high etching resistance, effectively protects the side surface of the connecting hole 9 from the attack of radical and the like and contributes to anisotropic etching. Since the deposited film thickness of the side-wall protecting film 11 is relatively thin, the reduction of the etching rate by a micro-loading effect is prevented.

Abstract: PURPOSE:To secure thermal contact between an anode cylinder and a radiation plate, by making an inner circular dimension of the radiating plates, which are fitted at least to an outer circle of the central part in the anode cylinder, slightly larger than an outer circle of the anode cylinder while a magnetron is not in operation. CONSTITUTION:A plural number of aluminum radiating plates 21 are jointed by heat transfer around a copper-made anode cylinder 14 which constitutes an oscillation unit 10 of a magnetron. Then, the radiating plates 21, which are fitted at least to an outer circle of the central part in the anode cylinder 14, are fitted so that an inner circular surface of the inside cylinder part 21a is formed with 0.05-0.2mm gap g against an outer circular surface of the anode cylinder 14 while the magnetron is not in operation. Radiation performance can be maintained superior by bringing the anode cylinder 14, heated at a given high temperature while in operation in heat-transfer contact with the radiating plates 21. Therefore, without the anode cylinder 14 affected by thermal expansion or contraction stress, each portion can be prevented from being deformed, capable of stabilizing its characteristics.

Filed: 1989-10-04
Abstract: PURPOSE:To avoid the deterioration in the yield by minimizing the step difference between the main surface of a semiconductor substrate and a gate electrode surface etc., on a thick insulating oxide film. CONSTITUTION:The main surface of a semiconductor substrate 1 is patterned from a silicon nitride film 6 and then selectively oxidized in high temperature oxidizing atmosphere to form a thick insulating oxide film 2 for element isolation. Next, when the silicon nitride film 6 is removed and the insulating oxide film 2 is removed halfway using an etching chemical solution comprising HF+ NH4F, the difference in the processes between the top 8 of an insulating film 2 and the main surface 7 of the semiconductor substrate 1 is cancelled. Next, a gate electrode 3, an impurity diffused layer 4, an interlayer insulating film 10, contact hole aluminum contacts 11a, 11b are formed. Through these procedures, the step difference on the semiconductor substrate surface can be minimized while making the miniaturization and high integration of pattern feasible thereby enabling the reliability to be enhanced.

Abstract: PURPOSE:To detect a degree of polarization and an anisotropy of light of a fluorescence, etc., with a high accuracy and at a high speed by taking out the light of the fluorescence, etc., from one direction, and also utilizing an optical modulation which has used an electro-optical effect. CONSTITUTION:When incident light 1 of a fluorescence, etc., is made to pass through a double refraction material element 6, it is separated into two linear polarizations 10, 11 being orthogonal to each other. Also, as for a crystal 7 for showing an electro- optical effect, electrodes 8a, 8b are attached to each opposed surface, and a high voltage is impressed to them by a high frequency voltage generator 5. Subsequently, the polarizations 10, 11 are made incident on the surface having no electrodes 8a, 8b of the crystal 7. In this state, when no voltage is impressed to the electrodes 8a, 8b, a slit 9 is installed so that one of them is made to pass through and the other is light-shielded, and when a voltage has been impressed, the voltage is set so that a refractive index of the crystal 7 is varied against each of them, and a passing relation of the slit 9 of the polarizations 10, 11 becomes reverse. Accordingly, a polarization component which passes through the slit 9 is shifted at every half period. Therefore, when they are detected by a photodetector 3 and analyzed by a signal processor 4, a degree of polarization can be measured.

Title: Motion-compensated interframe encoding device
Inventor: UMA SHINICHI
IPC: H04N19/70
Filed: 1991-10-09
Abstract: PURPOSE:To reduce the motion vector searching time of the motion compensated interframe encoding device by reducing the interframe error calculating time of the device to the half of its all picture element calculating time. CONSTITUTION:A TV signal 1 is written in the current frame memory 3 after it is digitized by means of an A/D conversion circuit 2 an generates a block- converted address through a frame memory control section 4. A motion compensating section 5 shifts the address of the preceding frame memory by the amount of a motion vector 6 by outputting the vector 6. The section 5 compares an interframe error 8 which is the difference between the output of the memories 3 and 7 with the vector 6 by changing the vector 6 and detects the vector 6 at which the error 8 becomes the minimum. Upon detecting the vector 6, the section 5 outputs the vector 6 at which the interframe error 8 becomes the minimum. The error 8 is quantized by means of a quantizer 9, encoded at an encoding section together with the vector 6, and transmitted to a transmission control circuit 11.

Title: Tape cassette and front lid opening/closing mechanism used therefor
Inventor: YAMASHITA TOMOHITO
IPC: G11B15/665
Filed: 1991-10-09
Abstract: PURPOSE:To correctly insert a tape cassette into a holder and to prevent a tape taking-up fault and a damage to the tape by providing a recessed part on a front lid of the tape cassette. CONSTITUTION:When the tape cassette 4 is inserted into the cassette holder 1, it goes down in the direction of the arrow A toward a chassis 8, and a fulcrum 10 of a lever 9 is moved in the left direction along a groove 11. A lever 12 is thereby moved and a connecting point 13 is rotated, then an arm 2 is rotated in the direction of the arrow B taking a rotating center 7 as the center. Since a lug 3 provided on the arm 2 enters into the recessed part provided on the front surface of front lid of the cassette 4 at this time, the front lid 5 is also rotated in the direction of the arrow B together with the arm 2 and opened. Then, the front lid 5 is also set in the opened state with the specified amount by the rotation of the arm. Consequently, the cassette 4 is prevented from deviating from the holder 1 by the repulsion of the force going to close the front lid 5, and the stable positioning is attained.

Title: Straight motion positioning device, and magnetic head inspecting device, magnetic disk inspecting device using the same
Inventor: MITARAI REIJI
IPC: B23Q1/38
Filed: 1998-09-16
Abstract: PROBLEM TO BE SOLVED: To realize the highly responsive control system at a low cost by making the distance to a guide surface from the position measuring part of a movable body where the position is measured by a measuring device, longer than the distance to the guide surface from the driving part at the time of driving a movable unit by an actuator. SOLUTION: The measuring position to measure the position of a table 1 is located at the place comparatively far from the yawing restricting position. When the attitude of the table 1 is fluctuated in the yawing direction by arranging the measuring position to the position far from the restricting position, the external disturbance due to the fluctuation of the yawing attitude affects the positional measurement of the table 1 in the translational direction. Therefore, a signal outputted by an encoder to measure the position of the table 1 in the direction X includes the external disturbance due to the fluctuation of the yawing attitude. By arranging the encoder, the feedback control of the translational operation of the table 1 is executed with controllability by using the positional signal including rotational components.
