While a wafer stage linearly moves in a Y-axis direction, a multipoint AF system detects surface position information of the wafer surface at a plurality of detection points that are set at a predetermined distance in an X-axis direction and also a plurality of alignment systems that are arrayed in a line along the X-axis direction detect each of marks at positions different from one another on the wafer. That is, detection of surface position information of the wafer surface at a plurality of detection points and detection of the marks at positions different from one another on the wafer are finished, only by the wafer stage (wafer) linearly passing through the array of the plurality of detection points of the multipoint AF system and the plurality of alignment systems, and therefore, the throughput can be improved.

A method of transferring a flexible layer to a substrate makes use of a partial bulge in the flexible layer, which does not make contact with the substrate. The partial bulge advances to the location of an alignment marker on the substrate. When alignment adjustments are needed, they are made with the partial bulge in place so that more reproducible positioning is possible when fully advancing the flexible layer against the substrate.

An edge-dominant alignment method for use in an exposure scanner system is provided. The method includes the steps of: providing a wafer having a plurality of shot areas, wherein each shot area has a plurality of alignment marks; determining a first outer zone of the wafer, wherein the first outer zone includes a first portion of the shot areas along a first outer edge of the wafer; determining a scan path according to the shot areas of the first outer zone; and performing an aligning process to each shot area of the first outer zone according to the scan path and an alignment mark of each shot area of the first outer zone.

An imprint apparatus includes a mold holder for holding a mold, a substrate holder for holding a substrate, a dispenser for arranging imprint material on the substrate, and a scope for capturing an image of a mark. The substrate holder includes a reference plate having a reference mark whose image is captured by the scope, the dispenser is arranged in a first direction when viewed from the mold holder, and the reference plate is arranged between a virtual straight line which is parallel to a second direction perpendicular to the first direction when viewed from the mold holder and passes through a center of the substrate holder, and an edge of the substrate holder located in the first direction when viewed from the virtual straight line.

A lithography apparatus is provided. The lithography apparatus includes a control unit that obtains information of an expected processing count to be processed in a lot by a transfer unit, obtains information of an accumulated processing count, in the transfer unit, of each of originals in a original storage unit, and preferentially selects, from the originals, an original whose process enable count before the accumulated processing count reaches a predetermined count is not smaller than the expected processing count.

A detection apparatus that detects a mark formed on a substrate is provided. The detection apparatus includes a substrate holder configured to hold the substrate, an optical system accommodated in the substrate holder, an image sensor configured to capture an image of the mark from the reverse surface side of the substrate through the optical system, and a processor configured to perform detection processing for the mark based on the image of the mark captured by the image sensor. The processor corrects a detection value of the mark based on the position of the mark on the substrate in the height direction and information concerning the telecentricity of the optical system.
