Abstract: A method of transferring semiconductor devices to a product substrate includes positioning a surface of the product substrate to face a first surface of a semiconductor wafer having the semiconductor devices thereon, and actuating a transfer mechanism to cause the transfer mechanism to engage a second surface of the semiconductor wafer. The second surface of the semiconductor wafer is opposite the first surface of the semiconductor wafer. Actuating the transfer mechanism includes causing a pin to thrust against a position on the second surface of the semiconductor wafer corresponding to a position of a particular semiconductor device located on the first surface of the semiconductor wafer, and retracting the pin to a rest position. The method further includes detaching the particular semiconductor device from the second surface of the semiconductor wafer, and attaching a particular semiconductor device to the product substrate.

Abstract: 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.

Abstract: 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.
