  • Publication number: 20220228850
    Abstract: Provided is an optical interference measuring apparatus including a measuring unit for acquiring an interferogram of an interference wave obtained by irradiating a measuring target and a reference surface with electromagnetic waves and causing reflected waves from a reflecting surface of the measurement target and reflected waves from the reference surface to interfere and a signal processing unit for configuring an intensity profile in the depth direction by performing Fourier transform of the interferogram. The signal processing unit is configured to estimate a parameter for a model formula for an assumed surface count, based on the model formula of an interferogram when it is assumed that the measurement target has a predetermined structure, to select an optimal model by a statistical technique from the model formula to which a parameter estimated for the assumed surface count is applied, and to reconfigure an intensity profile based on the optimal model.

  • Patent number: 9541920
    Abstract: In a method for positioning a transfer unit including, support pins for supporting object, and a pick having at a leading end thereof a detection unit for detecting presence or absence of the object, a height reference position of the pick is determined by detecting an upper edge of one of the support pins by the detection unit. A forward moving angle of the pick is corrected by obtaining a deviation angle between a radial direction of the mounting table passing through the corresponding support pin and a forward moving direction of the pick. A forward movement starting point of the pick is corrected by obtaining a horizontal deviation distance between the radial direction of the mounting table and the forward moving direction of the pick. A forward moving reference amount of the pick is obtained from coordinates of the corresponding support pin.

  • Publication number: 20160169766
    Abstract: A leakage determining method determines whether or not atmospheric air enters a vacuum transfer chamber for transferring a substrate under a vacuum atmosphere between a preliminary vacuum chamber and a processing chamber. The method includes controlling a pressure in the vacuum transfer chamber to a preset pressure by supplying a pressure control gas into the vacuum transfer chamber; performing supply control, when the substrate is not transferred, by reducing the amount of the pressure control gas supplied into the vacuum transfer chamber or stopping the supply of the pressure control gas; and measuring an oxygen concentration in the vacuum transfer chamber after the supply control of the pressure control gas and determining leakage of atmospheric air into the vacuum transfer chamber by determining whether or not atmospheric air whose amount exceeds a preset allowable level enters the vacuum transfer chamber based on temporal changes of the measured oxygen concentration.

  • Patent number: 8318238
    Abstract: A substrate processing system includes a processing chamber 12, and an orienter 16 centering a wafer W. The orienter 16 is provided with an orienter sensor 42 measuring a central position discrepancy of the wafer W, and an image sensor 41 measuring a width of a non-film forming portion at circumferential portions of the wafer W. After a film deposition processing in the processing chamber 12, the wafer W is loaded into the orienter 16 where a central position discrepancy of the wafer W is measured, and the wafer W is then centered. Further, the width of the non-film forming portion of the wafer W is measured, and a film position discrepancy is calculated based on the width of the non-film forming portion. To correct the calculated film position discrepancy, a target transfer position of the wafer W on a mounting table 13 in the processing chamber 12 is adjusted.

  • Patent number: 7697745
    Abstract: In an enclosure inspection apparatus 11, when a sealed letter 2 is inputted into a sealed letter loading station A, visual inspecting means 27 and X-ray inspecting means 33 determine thickness of the sealed letter and whether an enclosure in the sealed letter is a predetermined suspected object. The sealed letter not less than a predetermined thickness is rejected in first sorting station D, and the sealed letter which is not thicker than the predetermined thickness and in which the suspected object is not detected is conveyed as it is to second sorting station G. As for the sealed letter which is not thicker than the predetermined thickness and in which the suspected object is detected, after the suspected object in the sealed letter is positioned in a positioning station E, a suspected object inspecting station F determines whether the above-described suspected object is a predetermined object, such as an explosive or a narcotic drug, using a terahertz wave.

  • Patent number: 7279067
    Abstract: In a port structure 16A in a semiconductor processing system 2, a door 20A is disposed in a port 12A defined by upright wall 52 and 54. A table 48 opposed to the port is disposed outside the system. Defined on the table is a mount region 76 for mounting an open type cassette 18A for a process subject substrate W. A hood 50 is disposed rotatable relative to the table. The hood defines in its closed position a closed space surrounding the mount region and port, the space having a size to receive the cassette. First ventholes 58 are formed in the upright walls and/or the door so as to introduce gas from within the system into the closed space in the hood. Second ventholes 72 are formed in the table so as to discharge the gas can be discharged out of the closed space.
