Abstract:
1. A method of repairing a semiconductor device including an electronic component, a heat sink provided over the electronic component via a bonding layer, and a press member that moves in the heat sink towards the electronic component, the method comprising: moving the press member, in a perpendicular or diagonal direction with respect to an upper end of the electronic component, towards the electronic component until a conical portion of the press member comes into contact with the upper end of the electronic component; turning the press member to apply pressure and to move the heat sink in a horizontal direction across the bonding layer on the electronic component; and removing the heat sink from the electronic component, wherein the movement of the heat sink on the electronic component reduces a shearing force in the bonding layer and reduces a bonding force of the bonding layer to separate the heat sink from the electronic component.
