IPC: F16K23/00
Filed: 1997-04-10
Abstract: PROBLEM TO BE SOLVED: To accurately control a flow rate of a fluid which is sucked by a flexible member, by providing a suck back mechanism which sucks the fluid in a flow path under the negative pressure which is generated by displacement of the flexible member, and controlling an amount of displacement of the flexible member under driving operation of a motor-driven linear actuator. SOLUTION: When a signal is output to a flow controlling means 68, pressured fluid is fed to a cylinder room 48 of an on/off valve mechanism 26, and pilot pressure is controlled to a given value. The fluid shifts a piston 50 against a spring member 54, a diaphragm 56 separates from a seat part 59, and the valve mechanism 26 is turned on. Thus, coating liquid flows along a flow path 38 and drips onto a semiconductor wafer. By turning off the valve mechanism 26, driving a linear actuator 118 of a suck back mechanism 28, and returning the coating liquid to the suck back valve 20 side using negative pressure operation of a diaphragm 100 which is raised under operation of a spring member 98, liquid is prevented from dripping.

Abstract: PURPOSE:To make it possible to perform excellently precise inspection and to reduce the cost by arranging a light receiving means on an optical axis at a position which is separated from a mirror. CONSTITUTION:Under the state wherein a body under inspection 8 is set in a gantry 1, laser light 4a is emitted from a laser unit 4. The light 4a is reflected from a reflecting mirror 15 and cast into a primary reflecting device 2. At this time, the light 4a is transmitted through a liquid-crystal shutter 11a in the OFF state, reflected into the direction perpendicular to the central line at a plane mirror 10a and further cast into the body under inspection 8. The light 4a which is transmitted through the body under inspection 8 is reflected into the direction of the central line from a shutter 11a in the ON state and cast into a plane mirror 12 of a secondary reflecting device 3. The reflected light 4a is condensed with an optical system 6 and cast into a light receiving unit 7. The intensity of the light 4a is measured with the unit 7. At this time, the unit 7 is separated from the mirror 15. Therefore, the effects of the heat and the vibration of the mirror 15 are not incurred, and the measuring accuracy is improved. Since the unit 7 is located on the optical axis, it is not necessary to provide a plurality of units, and the cost can be decreased.

Filed: 1989-04-12
Abstract: PURPOSE:To highly integrate a semiconductor device by a method wherein a bonding pad for external connection use is used also as a pad for measurement use of a characteristic-checking pattern. CONSTITUTION:A voltage is applied to a gate electrode 2 of a transistor for measurement use from a bonding pad 9 for external connection use via a semiconductor input-protective device (resistor 1). Accordingly, a surge voltage which has been applied to the bonding pad 9 for external connection use is absorbed by the resistor 1 and by transistors (18, 12, 17) for protective use and does not destroy a gate oxide film of a transistor characteristic-checking pattern. As a result, the bonding pad 9 for external connection use can be used as one of pads for measurement use of the transistor characteristic- checking pattern. Thereby, a semiconductor device can be integrated highly.
