Abstract
A semiconductor-chip exfoliating device for exfoliating a semiconductor chipfrom an adhesive sheetis provided. The device includes a backup holderfor holding the adhesive sheetso that semiconductor chipsturn upward, a pair of needle pins arranged on a backside of the holderto lift off the adhesive sheetfrom the holderthrough through-holesin the holderand a sliding unitarranged on the backside of the holderto slide one needle pinin a direction to depart from the other needle pin. By the sliding unit, the interval between the needle pinscan be changed so as to cope with a variation of semiconductor chipsA.
