Abstract
An electrical conductor is connected to a first microcircuit element having a first connector site axis and a second microcircuit having a second connector site axis. The first microcircuit and the second microcircuit are separated by and operatively associated with a first electrical insulator layer. The conductor and the first microcircuit element are separated by and operatively associated with a second electrical insulator layer. At least one of the first electrical insulator layer and the second electrical insulator layer comprise a polymeric material. The microcircuit includes a UBM and solder connection to a FBEOL via opening. Sufficiently separating the first connector site axis and the second connector site axis so they are not concentric, decouples the UBM and solder connection to the FBEOL via opening. This eliminates or minimizes electromigration and the white bump problems. A process comprises manufacturing the microcircuit.
