Title: Cleaning of semiconductor substrate
Inventor: SAEKI SHIGEHIRO
IPC: B08B3/04
Filed: 1988-02-03
Abstract: PURPOSE:To prevent dust from attaching again to wafer surface when taking out the wafer, by putting a primary cleaning solution with a small specific gravity into a cleaning tank to a clean a semiconductor substrate and by thereafter putting a secondary cleaning solution with a larger specific gravity into the cleaning tank to make the primary cleaning solution flow out. CONSTITUTION:After a wafer 4 is put into a cleaning tank 1 by using a wafer carrier 5, alcohol 3A is put from an inlet 2 as a cleaning solution to clean the wafer 4. Pure water 3B whose specific gravity is larger than that of alcohol flows as secondary cleaning solution from the inlet 2. Since the inflow rate of pure water is 2.5l/min to prevent the pure wafer from being mixed with alcohol, alcohol 3A flows out of the cleaning tank from the upper side of the tank without mixed with pure wafer 3B with a larger specific gravity and dust 6 remaining within alcohol 3A also flows out of the tank at the same time. In this way, when the wafer 4 is took out of the tank 1, re-attachment of dust 6 to the wafer 4 is minimized.

Title: Rotating speed detecting device
Inventor: MORIMURA NAOKI
IPC: B60T8/00
Filed: 1999-02-02
Abstract: PROBLEM TO BE SOLVED: To stabilize detection accuracy by means of a sensor upon minimization of the uselessness in the constitution of a rotating speed detecting device. SOLUTION: A support ring body 40 is used only for mounting a sensor 20, and a pulser ring 10 is directly mounted on an extended position of a rotation side member 5a without using the support ring body 40. This constitution reduces the number of part items compared with that in conventional devices. In addition, since the deformation of the support ring body 40 as might occur in such conventional methods that require the use of a support ring in mounting a pulser ring can be eliminated, the arranging position of the pulser ring 10 does not shift, which makes it easy to properly control the opposing gap between the pulser ring 10 and the sensor 20.

Filed: 1996-02-13
Abstract: PROBLEM TO BE SOLVED: To elongate operation life by providing one or a plurality of spiral grooves, which are the grooves preventing the splash of oil and extending in the outer surface in the same direction as the rotating direction of a rotary shaft. SOLUTION: When a motor is rotated, lubrication oil is transmitted to a frame 5 from a rotary shaft and flows into the outer surface direction by centrifugal force. In the lubrication oil, the resultant force of the direction of the force directed outward from the center of a rotary shaft 2 and the force in the reverse direction from the motor rotation by air resistance is received. The lubrication oil is collected in a groove 12 provided on the frame 5. The groove 12 has the spiral shape and extends outward in the same direction as the rotating direction of the motor. The direction is reverse to the force of the direction where the force is applied on the lubricating oil. Therefore, the lubrication oil collected in the spiral groove 12 when the motor is rotated is transmitted on the wall of the groove 12 and returned to the central direction of the motor.

Abstract: PURPOSE:To easily form black stripes in accordance with the trend toward the higher fineness without requiring mask alignment by applying a black photosensitive resin on a substrate surface formed with metallic films having a light shielding effect on transparent electrodes, then exposing the black photosensitive resin from the rear surface of the substrate. CONSTITUTION:A thin ITO film 2 is formed on the glass substrate 1 and a photoresist 8 is applied thereon and is patterned and dry etched to form the stripe-shaped transparent electrodes 2. The metallic films 7 consisting of Ni-P are then formed by plating on the transparent electrodes 2. The metallic films 7 are not deposited on the glass 1 at this time. The black photosensitive resin 9 of a negative type is then applied thereon and is exposed from the rear surface. Since the metallic films 7 act as a photomask at this time, the photosensitive resin 9 remains only in the space parts by developing and the black stripes 3 having the light shielding effect are formed. The metallic films 7 are thereafter removed by etching. The removal of the black stripes 3 is not executed in this way.
