Claim 13:
14. A substrate-bonding device, comprising:
a carrier including a carrying surface for carrying a first substrate; wherein the carrying surface is provided a placement area, and the first substrate is provided with a first angular feature as a first flat edge or a first notch;
at least three aligning units disposed around the placement area of the carrying surface for approaching or leaving the placement area to align the first substrate and a second substrate; wherein the second substrate is provided with a second angular feature, and the second angular is a second flat edge or a second notch;
at least three support units disposed around the placement area of the carrying surface, for approaching or leaving the placement area and for supporting the second substrate; wherein each of the at least three support units includes a lower portion and a protruding portion protruding from the lower portion toward the placement area, and for each of at least three support units, the lower portion is disposed nearer to the carrying surface than the protruding portion is;
a pressing plate facing the carrying surface 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.
