  • Publication number: 20090035105
    Abstract: Provided are an apparatus, method for separating a chip and a method for fabricating the apparatus. An apparatus for separating a chip, according to example embodiments, may include a suction holder. The suction holder may include an upper surface with at least one suction hole to suction and fix an adhesive tape to which a plurality of semiconductor chips may be attached. The apparatus for separating a chip may also include a rotatable plunger in the suction holder. The rotatable plunger may include an upper end configured to pass through the at least one suction hole and to project over the suction holder upon rotation of the rotatable plunger. The apparatus for separating a chip may also include a vertically movable plunger lifter.
