Patent Images
1. An apparatus to directly transfer a first semiconductor device die to a substrate from a wafer tape having a first side and a second side, the first semiconductor device die being disposed on the first side of the wafer tape, the substrate including a second semiconductor device die onto which the first semiconductor device die is to be transferred, the apparatus comprising:
- a first frame to hold the wafer tape;
a second frame to hold the substrate adjacent to the first side of the wafer tape;
a needle disposed adjacent to the second side of the wafer tape and extending in a direction toward the wafer tape; and
a needle actuator connected to the needle to move the needle, during a direct transfer process, to a die transfer position at which the needle contacts the second side of the wafer tape to press the first semiconductor device die into contact with the second semiconductor device die,wherein a bond between the first semiconductor device die and the second semiconductor device die is induced such that the first semiconductor device die is released from the wafer tape and is attached to the second semiconductor device die.

8. A system for performing a direct transfer of a first semiconductor device die to a substrate from a wafer tape having a first side and a second side, the first semiconductor device die being disposed on the first side of the wafer tape, the substrate including a second semiconductor device die onto which the first semiconductor device die is to be transferred, the system comprising:
-
a first conveyance mechanism to convey the wafer tape; a second conveyance mechanism to convey the substrate with respect to the wafer tape; a transfer mechanism disposed adjacent to the first conveyance mechanism to effectuate the direct transfer; a controller including one or more processors communicatively coupled with the first conveyance mechanism, the second conveyance mechanism, and the transfer mechanism, the controller having executable instructions, which when executed cause the one or more processors to perform operations including; determining a position of the second semiconductor device die based at least in part on map data, the map data describing where the first semiconductor device die is to be transferred onto the second semiconductor device die, conveying at least one of the wafer tape or the substrate such that the substrate is adjacent to the first side of the wafer tape and disposed relative to the second conveyance mechanism to permit stacking of the first semiconductor device die onto the second semiconductor device die, orienting the transfer mechanism to a position adjacent to the second side of the wafer tape, and activating the transfer mechanism to contact the second side of the wafer tape to press the first semiconductor device die into contact with the second semiconductor device die such that the first semiconductor device die is released from the wafer tape and is attached to the second semiconductor device die. - View Dependent Claims (9, 10, 11, 12)
