Abstract:
1. A microfeature die, comprising: a substrate having a bond site and integrated circuitry electrically coupled to the bond site; a redistribution structure coupled to the substrate, the redistribution structure having an external contact site configured to receive an electric coupler; a conductive line having a transmission length, wherein the conductive line is electrically connected to the external contact site and the bond site; a conductive shield at least partially surrounding the conductive line along at least a portion of the transmission length of the conductive line, wherein the conductive shield includes a first metal layer and a second metal layer electricity coupled to the first metal layer; wherein the redistribution structure further includes a first dielectric layer positioned between the substrate and the first metal layer, a second dielectric layer positioned between the first metal layer and the conductive line, and an opening extending through the first dielectric layer, through the first metal layer, and through the second dielectric layer; and wherein the conductive line extends through the opening, and the second dielectric layer electricity isolates the conductive line from the first metal layer.
