Abstract:
An apparatus for removing semiconductor chips from a semiconductor wafer, comprising, in combination:a diced semiconductor wafer having a plurality of diced semiconductor chips;a transparent flexible sheet located below and in contact with said diced semiconductor wafer; andX--Y--Z means located below said transparent flexible sheet and having a round probe member assembly for selectively elevating one of said plurality of diced semiconductor chips by pressing against a rear portion of said transparent flexible sheet to bend said transparent flexible sheet to elevate said one of said plurality of diced semiconductor chips,wherein said X--Y--Z means comprising a bar member having said round probe member assembly coupled thereto for movement therewith, means for moving said bar member in one of an X direction and a Y direction, and means for moving said round probe member assembly in both the other of said X direction and said Y direction and in a Z direction to bend said transparent flexible sheet to elevate said one of said plurality of diced semiconductor chips,wherein said means for moving said round probe member assembly comprising handle member means coupled to said round probe member assembly for pivotally and selectively raising and lowering said round probe member assembly, and sliding means for permitting said round probe member assembly and said handle member means coupled thereto to be moved in the other of said X direction and said Y direction.
