Direct transfer apparatus for a pattern array of semiconductor device die
An apparatus includes a transfer element that is disposed adjacent the wafer tape. A tip end of the transfer element has a footprint sized so as to span across a group of dies on the wafer tape. An actuator is connected to the transfer element to move the transfer element to a die transfer position at which the transfer element presses on the wafer tape to press the group of dies into contact with a circuit trace on the product substrate.
1. A transfer element for transferring semiconductor device die (“die”) directly from a wafer tape to a circuit, the transfer element moveable between a first position and a second position, and the transfer element comprising:
a main body; and
a single tip end at an end surface of the main body, the single tip end being the furthest distal end of the transfer element and the single tip end having a footprint sized so as to span across a group of die including more than one die on the wafer tape, wherein the single tip end is configured to directly contact and press against the wafer tape to simultaneously press each die of the group of die into contact with the circuit in the second position, thereby transferring the group of die onto the circuit.
2. The transfer element according to claim 1 , wherein the main body is an elongated pin.
3. The transfer element according to claim 1 , wherein the footprint of the tip end of the transfer element has a predetermined shape that corresponds to a shape arrangement of the plurality of dies being transferred.
4. The transfer element according to claim 1 , wherein the footprint of the tip end of the transfer element has a predetermined shape that corresponds to the shape of a logo, mark, name, sign, or other symbol.
5. An apparatus, comprising:
a transfer mechanism to transfer a plurality of electrically-actuatable elements directly from a wafer tape to a product substrate, the transfer mechanism including a transfer element with a single tip end sized so as to span across a group of electrically-actuatable elements including more than one electrically-actuatable element, wherein the single tip end is the furthest distal end of the transfer element, and the transfer element is moveable between a first position and a second position, wherein the transfer element is configured to directly contact and press against the wafer tape to simultaneously press each electrically-actuatable element of the group of electrically-actuatable elements into contact with the product substrate in the second position, thereby transferring the group of electrically-actuatable elements simultaneously onto the product substrate.
6. The apparatus according to claim 5 , wherein the transfer mechanism further includes an actuator that moves the transfer element toward and away from the wafer tape.
7. The apparatus according to claim 5 , wherein the tip end of the transfer element is shaped as an elongated bar that facilitates a direct transfer of a linear sequence of at least two dies simultaneously.
8. The apparatus according to claim 5 , wherein the tip end of the transfer element has a shape that facilitates transfer of a non-linear sequence of more than two dies simultaneously.
9. The apparatus according to claim 5 , wherein the tip end includes a footprint that includes a predetermined shape that corresponds with a symbol.
10. The apparatus according to claim 5 , wherein the tip end is reconfigurable.
11. The apparatus according to claim 10 , wherein the tip end includes a plurality of micro needle heads.
