Abstract
A system for transfer of a plurality of die from a die source to a receive substrate is provided. The system includes a die source including a plurality of die, the plurality of die being coupled to a carrier. The system also includes a receive substrate to receive the plurality of die from the die source. The receive substrate includes a die catch material for receiving the plurality of die from the die source, the die catch material being reusable. The system also includes a laser source for providing energy to interact with a die release material to transfer the plurality of die from the die source to the receive substrate.
Claims19
A system for transfer of a plurality of die from a die source to a receive substrate, the system comprising:
- a die source including a plurality of die, the plurality of die being coupled to a carrier;
- a receive substrate to receive the plurality of die from the die source, the receive substrate including a die catch material for receiving the plurality of die from the die source, the die catch material including an energy absorbing portion and an adhesive portion, the energy absorbing portion of the die catch material being reusable;
- and
- a laser source for providing energy to interact with a die release material to transfer the plurality of die from the die source to the receive substrate.
A method of transferring a plurality of die from a die source to a receive substrate, the method comprising the steps of:
- (a) coupling a plurality of die to a carrier via a die release material, thereby assembling a die source;
- and
- (b) applying energy to the die release material using a laser to transfer the plurality of die from the die source to a receive substrate, the receive substrate including a die catch material for receiving the plurality of die from the die source, the die catch material including an energy absorbing portion and an adhesive portion, the energy absorbing portion of the die catch material being reusable.
A system for transfer of a plurality of die from a die source to a receive substrate, the system comprising:
- a die source including a plurality of die, the plurality of die being coupled to a carrier;
- a receive substrate to receive the plurality of die from the die source, the receive substrate including a die catch material for receiving the plurality of die from the die source, the die catch material being reusable;
- a laser source for providing energy to interact with a die release material to transfer the plurality of die from the die source to the receive substrate;
- and
- a pick tool configured to make contact with one of the plurality of die on the receive substrate and move the one of the plurality of die away from the receive substrate.
