Method for transfer of semiconductor devices onto glass substrates
A method for transferring a plurality of die operatively associated with a transfer apparatus to a glass substrate to form a circuit component. 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.
Systems for direct transfer of semiconductor device die
A system for performing a direct transfer of a semiconductor device die includes a first conveyance mechanism to convey a first substrate, and a second conveyance mechanism to convey a second substrate with respect to the first substrate. The first substrate includes a first side and a second side, and the semiconductor device die is disposed on the first side of the first substrate. The second conveyance mechanism includes a first portion and a second portion to clamp the second substrate adjacent to a first side of the first substrate. The first portion of the second conveyance mechanism has a concave shape and the second portion of the second conveyance mechanism has a convex counter shape corresponding to the concave shape of the first portion. The system also includes a transfer mechanism disposed adjacent to the first conveyance mechanism to effectuate the direct transfer.

A substrate is loaded into a second frame, the substrate including a second semiconductor device die onto which the first semiconductor device die is to be transferred. A needle is oriented to a position adjacent to the second side of the wafer tape, the needle extending in a direction toward the wafer tape, and a needle actuator connected to the needle is activated to move the needle 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.
Method for improved transfer of semiconductor die
A system to effectuate improved transfer of semiconductor die. A first frame secures a first substrate having the semiconductor die. A second frame secures a second substrate adjacent the first substrate. A needle is disposed adjacent to the first frame.

A needle actuator is operably connected to the needle and is configured to actuate the needle such that, during the transfer operation, when the first substrate is secured in the first frame and the second substrate is secured in the second frame, the needle presses the semiconductor die into contact with the second substrate so as to transfer the semiconductor die onto the second substrate.
