摘要:
A measuring apparatus according for measuring relative positions between a first mark on a movable reticle stage to hold a reticle, and a second mark on a movable object stage to hold an object to be exposed, the apparatus includes a detector for detecting light that has passed the first and second marks, and a processor for calculating the relative positions based on an output of the detector, wherein each of the first and second marks includes plural patterns to direct the light, at least ones of widths and intervals of the plural patterns being non-uniform.
摘要:
A differential pumping system includes a first chamber for storing a light source that emits light, a second chamber that receives light from the first chamber, and a vacuum pump, provided between the first and second chambers, which includes a hollow shaft through which the light passes, and exhausts the hollow shaft.
摘要:
A measurement apparatus has a first detector for measuring an intensity such that a sheet-shaped beam of synchrotron radiation is integrated over the entire range of the beam in the thickness direction thereof; a second detector for measuring the intensity of the beam at two points where positions along the direction are different; and a calculating device for calculating the magnitude of the beam in the direction on the basis of the detections by the first and second detectors.
摘要:
Factories (102-104) have host computers (107) for monitoring industrial equipments (106). Each host computer (107) is connected to a management host computer (108) on a vendor (101) side through the internet (105). The host computer (107) on the factory side detects occurrence of a trouble of the industrial equipment (106) and notifies the vendor side of status information representing a trouble state. In response to this, the host computer (108) on the vendor side notifies the factory side of response information representing a countermeasure against the trouble state.

摘要:
A discrimination apparatus and method usable in an exposure apparatus for transferring a pattern of an original onto a substrate includes a device and step for producing information related to the relative positional deviation between the original and the substrate, and a device and step for discriminating an error shot on the basis of the information. The condition for positioning discrimination is changed in accordance with a layer or shot.
