Patent ID: 8142611

Claim:
A semiconductor-chip exfoliating device for exfoliating a semiconductor chip from an adhesive sheet to which a plurality of semiconductor chips are adhered, comprising: a holder that holds the adhesive sheet so that the semiconductor chips turn upward; at least two first through-holes formed in the holder; at least two lift-off pins arranged on a backside of the holder to lift off the adhesive sheet from the holder through the first through-holes; and a sliding unit arranged on the backside of the holder and including a slide shaft provided with second through-holes, wherein the second through-holes include an elongated hole that allows an insertion of one of the lift-off pins and a relative movement of the one of the lift-off pins in a direction transverse to an axis of the one of the lift-off pins, and another hole that allows an insertion of another of the lift-off pins, wherein the sliding unit makes the one of the lift-off pins inserted through the elongated hole slide along the transverse direction via the slide shaft laterally with respect to the another one of the lift-off pins inserted through the another hole to thereby change an interval between the lift-off pins.
