Abstract:
1. A Smart Card chip module comprising: a semiconductor Smart Card chip having a first length, a width, a first thickness, and first and second metallic contact bumps of a height; a substrate consisting of an insulating bottom layer and an metal top layer adhering continuously to the insulating bottom layer, the metal layer patterned into a strap having a first and a second half separated by a hiatus smaller than the first length; a sheet-like metallic carrier, the carrier having a second thickness about equal to the sum of the first thickness and the bump height, the carrier patterned into a first and a second portion separated by a gap having a width at least equal to the first length for receiving the chip wherein a top of the carrier is substantially the same height from the substrate as the mounted chip; the carrier conductively contacting the substrate so that the first carrier portion rests on and is electrically connected to the first strap half, the second carrier portion rests on and is electrically connected to the second strap half, and the hiatus is approximately in the center of the gap, wherein the insulating substrate layer bridges the carrier gap; the chip in contact with the substrate so that the first length is within the carrier gap, the first bumps contacting the first strap half and the second bumps contacting the second strap half, wherein the chip spans over the hiatus between the halves and wherein the chip is electrically connectable to an external circuit via the strap and the carrier; an adhesive polymer compound filling the space under the chip span and filling the hiatus; and an encapsulation compound filling any space of the carrier gap not occupied by the chip.
