    摘要: PROBLEM TO BE SOLVED: To provide a gas gage improving sensibility measuring partial differences of profiles for wafers for usage in a lithographic device. SOLUTION: The gas gauge includes a gas delivery pipe arranged so as to divide a distance up to an object. The gas delivery pipe includes a gas conduit, and supplies a proper measuring gas through the gas conduit. The measuring gas is discharged from the gas delivery pipe through an outlet under a pressure to collide with the object in an interaction region and the pressure of a rebounded gas is measured by a pressure detector. The gas having a small atomic number is used. A pressure sensor includes a thin film arranged in the gas delivery pipe at least partially surrounding the gas conduit in a gas outlet or a vicinity of the gas outlet. The pressure sensor includes a thin-film disk arranged around the gas conduit. The pressure sensor is disposed substantially on a common surface, and isolated from the gas conduit but includes a plurality of proper pressure elements for surrounding the gas conduit.

    摘要: PROBLEM TO BE SOLVED: To solve the problem that it takes a time to discriminate a distance, because many times necessary for completion of a back pressure rise are needed if the distance to an object to be detected becomes not more than 10 μm. SOLUTION: In a deposition distance determination device, a regulator 1 to be set a detection pressure is mounted inside or outside, and a two port solenoid valve 2 to cut a supply air is mounted. Further, in secondary side of the two port solenoid valve 2, a pressure transducer 3 (a pressure sensor, a pressure switch, a pressure transducer or the like) is mounted. A control circuit which controls the two port solenoid valve 2 and the pressure transducer 3 is installed. A piping into a detecting orifice which is prepared a detection surface of the object to be detected is mounted. And from the orifice 5 to the object to be detected, air is made to flow. For the two port solenoid valve 2, either normal open type or normal close type can be used, in this case, what is necessary is to control so as to intercept air, whenever performing detection on the control circuit. For an error due to temperature of the pressure transducer 3, correction can be made by using air temperature sensor inside the piping, and temperature sensor at outside of the piping.

    摘要: PROBLEM TO BE SOLVED: To provide a gas gauge proximity sensor having a choked flow orifice for sensing a difference between a reference surface standoff and a measurement surface standoff.
    SOLUTION: Unlike an existing proximity sensor, the gas gauge proximity sensor of the present invention replaces the use of a mass flow controller with the choked flow orifice. The use of the choked flow orifice provides a reduction in device cost and an improved system reliability. A gas supply forces gas into the proximity sensor. The gas flow is forced through the choked flow orifice so as to achieve a sonic condition at which a mass flow rate becomes largely independent of pressure variations. The flow of gas proceeds from the choked flow orifice into a sensor flow channel system. A mass flow sensor within the sensor flow channel system monitors the flow rate to detect the measurement standoffs that can be used to initiate a control action.
