    Abstract: A die pickup apparatus including a wafer sheet push-up unit provided inside a suction stage that suction-holds a wafer sheet having thereon dies. The wafer sheet push-up unit is made of push-up members, and the inner most push-up member is connected to a linking up-and-down moving shaft, so that when the linking up-and-down moving shaft is raised, the outer most push-up member in contact with the linking up-and-down moving shaft is raised, raising telescopically the inner push-up members. The outermost push-up member has a stopper that is adjustable in its up-and-down positions and comes into contact with the suction stage to stop the rising motion of the outermost push-up member, and the next inner side push-up member has its own stopper that is adjustable in its up-and-down positions and comes into contact with the outermost push-up member to stop the rising motion of the intermediate push-up member.
