Abstract

A flip chip IC device utilized in RF transceivers includes a bare die having a number of metalized pads and each metalized pad has a solder ball deposited thereon. The flip chip IC device further includes a substrate having a number of connector pads corresponding to the metalized pads. The connector pads are connected to one or more electronic components disposed on the substrate via a number of connector strips. The bare die is flipped up-side-down such that the metalized solder pads are aligned and connected with the connector pads of the substrate via the solder balls. At least one of the connector strips includes a strip section having an uneven strip width configured to compensate an impedance of a transmission line formed based on a connection between a metalized pad of the bare die and a connector pad of the substrate to match predetermined impedance.
