Patent ID: 7896051

Claim:
A die bonding apparatus, comprising: a substrate transportation unit for transporting a first substrate and a second substrate; a mount table disposed adjacently to the substrate transportation unit and adapted to loading a plurality of semiconductor chips; a first bonding head unit including a first bonding head for bonding as least one of the semiconductor chips loaded in said mount table to an upper portion of the first substrate; a die transportation unit for transporting at least one of the semiconductor chips loaded in said mount table to a mount stage disposed at a lower portion of the second substrate; a second bonding head unit including the mount stage and a second bonding head disposed at an upper portion of the second substrate corresponding to the mount stage and adapted to bonding at least one of the semiconductor chips disposed in the mount stage to the lower portion of the second substrate, wherein the ratio of bonding head units to mount stages is at least 2 to 1; wherein the first bonding head unit comprises: a first pick-up unit for picking up the semiconductor chip disposed in said mount table; and a first transportation unit for transporting the first pick-up unit to the first substrate disposed in the substrate transportation unit; and wherein the die transportation unit comprises: a second pick-up unit for picking up the semiconductor chip disposed in said mount table; and a second transportation unit for reciprocating the second pick-up unit between said mount table and the mount stage.
