Document Type and Number:
WIPO Patent Application WO/2008/047731
Kind Code:
A1
Abstract:
[PROBLEMS] To provide a pickup method and a pickup apparatus wherein pushing up of a chip is not required and a force for holding a chip which is not picked up is not varied as pickup progresses. [MEANS FOR SOLVING PROBLEMS] A method is provided for picking up a chip (13) from a fixed jig (3) to which the chip (13) is fixed. The fixed jig (3) consists of a jig base (30) having a plurality of protrusions (36) on one side and a sidewall (35) of substantially the same height as that of the protrusion (36) at the outer circumference of the one side, and an adhesion layer (31) laminated on the surface of the jig base (30) having the protrusions (36) and bonded on the upper surface of the sidewall (35). A section space (37) is formed on the surface of the jig base (30) having the protrusions by the adhesion layer (31), the protrusions (36) and the sidewall (35), and at least one through hole (38) penetrating the outside and the section space (37) is provided in the jig base (30). The pickup method comprises a step for fixing a chip, a step for deforming the adhesion layer (31) by sucking air in the section space (37) through the through hole (38), and a step for picking up the chip (13) completely from the adhesion layer (31) by sucking the chip (13) from the upper surface side of the chip (13) by means of a suction collet (70).
