Claim:
1. A semiconductor chip testing apparatus for picking up and testing semiconductor chips, the apparatus comprising: an upper socket unit having a receiving space defined therein to receive an upper semiconductor chip, the upper socket unit configured to a blade block coupled to the upper socket unit and configured to deliver a vacuum pressure for generating the suction airflow in the receiving space; and a lower socket unit configured to wherein the upper socket unit comprises wherein the blade block comprises a first suction hole, wherein the socket body comprises a second suction hole formed in the concave groove portion and passing through the top side and the concave groove portion of the bottom side, wherein the socket block comprises a third suction hole connected to the suction nozzle, wherein a flow path for the suction airflow through the upper socket unit is defined by a sequential connection of the suction nozzle, the third suction hole, the receiving space, the second suction hole, and the first suction hole, to generate a suction force allowing the suction nozzle to pick up the lower semiconductor chip, and wherein the concave groove portion comprises
