Claim 0:
1. 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, the first substrate is provided with a first angular feature, and the first angular feature is a first flat edge or a first notch;
at least three first aligning units disposed around the placement area of the carrying surface, for approaching or leaving the placement area, so as to align the first substrate and to support a second substrate provided with a second angular feature which is a second flat edge or 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, 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, so as to align 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 of the carrier; and
a plurality of flat-edge aligners disposed aside of the placement area of the carrying surface for contacting the first flat edge of the first substrate and the second flat edge of the second substrate; wherein the plurality of flat-edge aligners are movable to ascend or descend with respect to the carrying surface along with the pressing plate.
