An apparatus includes a first frame to hold a wafer tape, and a second frame to hold a substrate adjacent to the first side of the wafer tape. A needle is disposed adjacent to the second side of the wafer tape and extends in a direction toward the wafer tape. A needle actuator is 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 a second semiconductor device die. An energy-emitting device is disposed adjacent to the substrate to induce a bond between the first semiconductor device die and 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.

A system to transfer an unpackaged die directly from a die holding substrate to a transfer location on a secondary substrate. The system includes a die separation device disposed adjacent to the die holding substrate to initiate separation of the unpackaged die from the die holding substrate. An energy source is disposed adjacent to the secondary substrate to apply energy to the transfer location and affix the unpackaged die directly to the secondary substrate. A sensor detects a position and orientation of the secondary substrate with respect to the unpackaged die on the die holding substrate. A processor is in communication with the die separation device, the energy source, and the sensor. The processor is configured to cause actuation of the die separation device and the energy source according, at least in part, to transfer instructions and data received from the sensor.

A lighting component including a plurality of die transferred to the glass substrate. The transfer occurs by positioning the glass substrate to face a first surface of a die carrier carrying multiple die. A reciprocating transfer member thrusts against a second surface of the die carrier to actuate the transfer member thereby causing a localized deflection of the die carrier in a direction of the surface of the glass substrate to position an initial die proximate to the glass substrate. The initial die transfers directly to a circuit trace on the glass substrate. At least one of the die carrier or the transfer member is then shifted such that the transfer member aligns with a subsequent die on the first surface of the die carrier. The acts of actuating, transferring, and shifting are repeated to effectuate a transfer of the multiple die onto the glass substrate.

An apparatus for performing a direct transfer of a die. The apparatus includes a first frame to hold the first substrate and a second frame to hold the second substrate. The apparatus further includes a transfer mechanism disposed adjacent to the first frame. The transfer mechanism includes a needle configured to press against the first substrate at a location collinear with the die. A controller, including one or more processors communicatively coupled with the first frame, the second frame, and the transfer mechanism, has executable instructions, which when executed, cause the one or more processors to perform operations including: determining a transfer position of the die on the first substrate via one or more sensors, and aligning the transfer position of the die with the needle of the transfer mechanism via movement of at least two of the first frame, the second frame, and the transfer mechanism.
