Claim Text:
1. A substrate bonding method of bonding a first substrate and a second substrate, the method comprising: detecting a mark of the second substrate held by a second member, using a first detection system, the second member being capable of opposing a first member that holds the first substrate; detecting a mark of the first substrate held by the first member, using a second detection system that is movable with respect to the first detection system; and overlaying the first substrate and the second substrate based on results of the detecting the mark of the second substrate and the detecting the mark of the first substrate, wherein in at least one of the detecting the mark of the second substrate and the detecting the mark of the first substrate, the first detection system is opposed to the second substrate when the second detection system is opposed to the first substrate, and wherein the detecting the mark of the second substrate and the detecting the mark of the first substrate are performed at least partially concurrently.
