Abstract:
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.

Claim (Index 12):
An obtaining method of obtaining characteristic information of an optical system accommodated in a substrate holder configured to hold a substrate, the method comprising obtaining information concerning telecentricity of the optical system by obtaining a first detection value of a position of a first mark on an adjustment substrate by capturing an image of the first mark from an obverse surface side of the adjustment substrate held by the substrate holder without going through the optical system using an image sensor and obtaining a second detection value of the position of the first mark by capturing an image of the first mark from a reverse surface side of the adjustment substrate through the optical system using the image sensor in each of a state in which the first mark on the adjustment substrate held by the substrate holder is at a first height position and a state in which the first mark is at a second height position different from the first height position.
