Abstract:
A CCD detector (30) captures an image of the circular arc shape of the outer periphery of a semiconductor wafer (W) that is on standby at a standby position (W1) near the inlet of a processing unit (1). A calculation section (40) detects, from the captured image of the circular arc shape, positional data on multiple positions of the shape, obtains an imaginary circle of the semiconductor wafer (W), calculates the center coordinates of the imaginary circle, and calculates "information on positional displacement" of the semiconductor wafer (W) at the standby position (W1). A controller (50) controls a conveyance device (12) based on the ''information on displacement'' to correct the position of the semiconductor wafer (W) on the processing unit (1).
Abstract:
In a vacuum treating apparatus including a treating vessel with delivery port adapted to have a vacuum atmosphere and perform treatment by a treating gas and a delivery chamber with vacuum atmosphere connected via a gate chamber to the delivery port of the treating vessel and equipped with delivery means for the pass and receipt of substrate, any diffusion of gas remaining in the treating vessel into the delivery chamber is suppressed. The vacuum treating apparatus comprises the treating vessel, the delivery chamber and a gate valve provided in the gate chamber so that the delivery port is closed when the substrate is treated in the treating vessel while the delivery port is opened when the pass and receipt of substrate for the treating vessel are carried out. In order to suppress any diffusion of gas remaining in the treating vessel into the delivery chamber, the gate chamber is furnished, at its position facing the delivery port, with a gate chamber inert gas supply part and a gate chamber exhaust port adapted to produce a stream of inert gas. This suppresses any diffusion of gas remaining in the treating vessel through the delivery port into the delivery chamber.
Abstract:
Disclosed is a method for running a treatment system provided with a plurality of process modules for subjecting substrates to mutually identical treatments. When each process module is conditioned for preparing the execution of a predetermined process recipe, at each completion of the conditioning of one process module, the sequential transfers of untreated substrates are started on a substrate transfer route from a cassette for housing the untreated substrates to that process module, and the sequential processes on the untreated substrates by using that process module are started. Even if the conditioning time periods are uneven between the process modules of identical specifications, the treatment system can be efficiently run.

The present invention provides a method for positioning a return device by which the workability of a teaching operation is improved, inter-operator deviation is reduced, and the risk of interference with an object to be processed is suppressed. The method for positioning a return device which has a maintaining pin portion maintaining a lower surface of a peripheral portion of the object to be processed and has a pick portion configured to be accessible to and separable from a mount configured to be pivotable and movable in an up-and-down direction and provided with a detection unit at a tip end to detect the presence and absence of the object to be processed, includes a height determining step in which a height reference position of the pick portion is determined through the detection of an upper end edge of the maintaining pin portion by the detection unit; an advance angle determining step in which the shift angle between the radial direction of the mount and the advance direction of the pick portion is determined and the advance angle of the pick portion is corrected; an advance starting point positioning step in which the shift horizontal distance between the radial direction of the mount and the advance direction of the pick portion is determined and the advance starting point position of the pick portion is corrected; and an advance amount determining step in which the advance reference amount of the pick portion is determined from the coordinates of the maintaining pin portion.

Abstract:
A film position adjusting method is provided to easily correct a discrepancy of a film depositing position in a substrate processing system. The substrate processing system is comprised of a process chamber (12), and an orienter (16) for centering of a wafer (W) to be carried in the process chamber (12). The orienter (16) is provided with an orienter sensor (42) for measuring a discrepancy at the central position of the wafer (W), and an image sensor (41) for measuring a width of a non-film depositing portion at circumferential portions of the wafer (W). Subjected to film deposition processing in the process chamber (12), the wafer (W) is carried to the orienter (16) where a discrepancy from the central position of the wafer (W) is measured, the wafer (W) is then subjected to centering, and the width of the non-film depositing portion of the wafer (W) is measured, and a film position discrepancy is calculated in accordance with the width of the non-film depositing portion. To correct the calculated film position discrepancy, a wafer carrying target position on a receiving plate (13) in the process chamber (12) is adjusted. ® KIPO & WIPO 2009

Abstract:
본 발명에 있어서는, 진공예비챔버내의 피처리체를 냉각하기 위한 냉각대에 피처리체와 냉각대 사이에 소정의 갭을 두고 피처리체를 지지하는 지지부재가 설치되어 있기 때문에, 피처리체를 냉각대와 직접 접촉시키지 않고 냉각시키는 것이 가능하게 된다. 따라서, 피처리체와 냉각대 사이의 면접촉에 기인하는 화학반응이 일어나지 않게 되어 피처리체가 오엽되지 않게 된다. 피처리체가 급속한 냉각에 의해 다소 휘어지거나 미소한 진동을 발생시킨다고 해도, 냉각대와 직접 접촉하지 않기 때문에, 파티클이 발생되지 않게 된다. 더욱이, 처리전의 피처리체를 예열하기 위한 예열장치가 냉각대 위에 설치된다. 따라서, 진공예비챔버를 처리후의 피처리체를 냉각하기 위해서 뿐만 아니라 처리전의 피처리체를 예열하는데 이용할 수 있고, 따라서 스루풋의 향상이 도모된다.
