Abstract
A semiconductor fabricating apparatus may include a collet structure configured to pick-up a semiconductor chip. The collet structure may include a holder, a plate, an absorption member and an edge contact. The holder may be configured to downwardly receive vacuum. The holder may include a magnet arranged in the holder. The plate may include an upper surface magnetically and mechanically combined with the holder. The plate may include a sidewall wholly exposed by the holder. The plate may receive the vacuum from the holder. The absorption member may make contact with the plate to pick-up the semiconductor chip using the vacuum received from the plate. The edge contact may include a protrusion having a first length protruded from an edge portion of a bottom surface of the holder to make contact with the plate.
