Classification: CPC H  B | IPC B  H

Claim 14:
15. An alignment method for a bonding machine, comprising:
placing a first substrate on a supporting surface of a support pedestal, wherein the supporting surface has a placement area;
three alignment members moving toward the placement area to position the first substrate placed on the supporting surface to align the first substrate with the placement area;
three support members moving toward the placement area and being used in supporting a second substrate; wherein each of the support members includes a protruding part and a base, the protruding part being protruding from the base and directed to the placement area, the base being closer to the supporting surface than the protruding part being to the support surface; wherein when the support members move toward the placement area and the first substrate, the bases of the support members position the first substrate;
the alignment members moving toward the placement area to position the second substrate supported by the support members to align the second substrate with the first substrate; and
the support members moving away from the placement area to place the second substrate thereon onto the first substrate.
