Abstract
A suction head of a pick-and-place tool for semiconductor device packaging is provided. The suction head includes: a suction unit configured to apply a suction force on a top die and pick the top die; and a warpage-correction mechanism. The warpage-correction mechanism includes a pushing mechanism, and the pushing mechanism includes a plurality of pushing units, each of the plurality of pushing units disposed in a corner region of the suction head. Each of the plurality of pushing units includes: a tubular chamber extending vertically relative to a bottom surface of the suction head; and a pusher disposed in the tubular chamber and in air-tight contact with a side wall of the tubular chamber. The pusher is movable vertically and capable of protruding out of the bottom surface of the suction head to push a corner region of the top die and apply a downward force thereon.
