Abstract:
1. A high-frequency transmission module, comprising: a first chip comprising a first top surface and a plurality of first pads arranged along a periphery of the first top surface, the first pads comprising a first bonding pad; a second chip comprising a second top surface and a second bonding pads on the second top surface, the second chip being positioned on the first top surface such that the first pads are uncovered by the second chip and the second bonding pad is close to the first bonding pad; a first conductive wire bonding to the first bonding pad and the second bonding pad to electrically connect the second chip to the first chip and configured to transmit high-frequency signals between the first chip and the second chip; a substrate; and a conductive adhesive laver, the substrate comprising a third top surface and a plurality of second pads on the third top surface, the first chip comprising a first bottom surface opposite to the first top surface and a plurality of third pads on the first bottom surface, the first chip being positioned on the substrate and electrically connected to the substrate by connecting the third pads to the respective second pads via the conductive adhesive layer.
