摘要： A packaged integrated circuit includes an integrated circuit having a Radio Frequency (RF) passive element formed therein and a wafer level chip scale flip chip package that contains the integrated circuit. The wafer level chip scale flip chip package includes at least one dielectric layer isolating a top metal layer of the integrated circuit and a package signal connection upon the at least one dielectric layer, wherein the package signal connection partially overlays the RF passive element with respect to a surface of the integrated circuit. The RF passive element may be an inductor, a transformer, a capacitor, or another passive element. The package signal connection may be a conductive ball, a conductive bump, a conductive pad, or a conductive spring, for example. A conductive structure may reside upon the at least one dielectric layer to provide shielding to the RF passive element and may include a plurality of conductive elements or a mesh.
