Abstract
A chip assembly includes a chip, a paddle, an interface layer, a frequency extending device, and lands. The chip has contacts. The interface layer is disposed between the chip and the paddle. The frequency extending device has at least a conductive layer and a dielectric layer. The conductive layer has conductive traces. The frequency extending device is disposed adjacent to the side of the chip and overlying the paddle. The lands are disposed adjacent to the side of the paddle. The contacts are connected to the conductive traces. The conductive traces are connected to the lands. The frequency extending device is configured to reduce impedance discontinuity such that the impedance discontinuity produced by the frequency extending device is less than an impedance discontinuity that would be produced by bond wires each having a length greater than or substantially equal to the distance between the contacts and the lands.
