Abstract:
1. An apparatus for mounting semiconductors, comprising a substrate table for supporting a substrate, a wafer table for presenting a semiconductor chip, whereby part of the wafer table is located underneath the substrate table, and a pick and place system for picking the semiconductor chip presented by the wafer table and placing the semiconductor chip onto the substrate, comprising a first shuttle, a second shuttle carrying a bondhead with a chip gripper, first guide elements for guiding the movement of the first shuttle along a first direction, second guide elements for guiding the movement of the second shuttle along a second direction, the second guide elements mounted on the first shuttle, a first linear motor comprising a first stationary stator and a first coil connected to the first shuttle, and a second linear motor comprising a second stationary stator and a second coil connected to the second shuttle.
