Patent ID: 8129225

Claim:
A method, comprising: providing first integrated circuit chips each comprising a first contact pad on a first main surface and a second contact pad on a second main surface opposite to the first main surface; arranging the first integrated circuit chips on an integral array of first carriers with the first main surfaces of the first integrated circuit chips facing the integral array of first carriers and the first contact pads being in electrical contact with the integral array of first carriers; and arranging an integral array of second carriers over the first integrated circuit chips with the second main surfaces of the first integrated circuit chips facing the integral array of second carriers and the second contact pads being in electrical contact with the integral array of second carriers, wherein the first carriers are electrically coupled to the second carriers and the second contact pads of the first integrated circuit chips by protruding resilient elements of the first or second carriers, wherein the protruding resilient elements of one of the first and second carriers are bent in a direction away from the other of the first and second carriers when the integral array of second carriers is arranged over the first integrated circuit chips and the other of the first and second carriers is pressed against the protruding resilient elements, and wherein the protruding resilient elements are integrally formed with the first carriers or the second carriers.
