Abstract:
1. A substrate stacking apparatus comprising: a first aligner that aligns a first substrate to a first substrate reference position and a second substrate to a second substrate reference position; a first table that receives and has the first substrate that has been aligned by the first aligner placed thereon; a second table that receives and has the second substrate that has been aligned by the first aligner placed thereon so as to oppose the first substrate, the second table being movable relative to the first table; and a second aligner that aligns, to a first substrate holder reference position, a first substrate holder adapted to hold the first substrate that has been aligned by the first aligner and aligns, to a second substrate holder reference position, a second substrate holder adapted to hold the second substrate that has been aligned by the first aligner, wherein the substrate stacking apparatus aligns, relative to each other, the first substrate and the second substrate while the first substrate is on the first table and the second substrate is on the second table and then stacks the first substrate and the second substrate on one another, and at least one of the first aligner and the second aligner performs alignment such that a positional relation between the first substrate and the first substrate holder and a positional relation between the second substrate and the second substrate holder fall in a predetermined range.
