Abstract
Disclosed is an element including a conductive feature at a contact surface of the element and a nonconductive region at the contact surface in which the conductive feature is at least partially embedded. The contact feature includes a conductive material and an amount of impurities at a grain boundary of the conductive material. The impurities have a non-alloying material that does not form an alloy with the conductive material at a bonding temperature.
