Claim 7:
8. A substrate-bonding device, comprising:
a carrier including a carrying surface for carrying a first substrate; wherein the carrying surface is provided with a placement area, and the first substrate is provided with a first notch;
at least three first aligning units disposed around the placement area of the carrying surface, for approaching and leaving the placement area, for aligning the first substrate, and for supporting a second substrate provided with a second notch; wherein each of the at least three first aligning units includes a lower portion and a protruding portion protruding from the lower portion toward the placement area, and for each of the at least three first aligning units the lower portion is disposed nearer to the carrying surface than the protruding portion is, and the lower portion is configured to align the first substrate;
at least three second aligning units disposed around the placement area of the carrying surface for approaching or leaving the placement area, and for aligning the second substrate supported by the at least three first aligning units;
a pressing plate facing the carrying surface of the carrier and movable with respect to the carrier, for pressing the first substrate and the second substrate stacked on each other on the carrying surface; and
at least one notch aligner for contacting the first notch of the first substrate and the second notch of the second substrate; wherein the at least one notch aligner is movable to ascend or descend with respect to the carrying surface along with the pressing plate.
