Abstract:
1. A method for making a microelectronic device with a reduced pitch between workpiece contacts, the method comprising: positioning a first workpiece contact in a first plane at a first side of a microfeature workpiece; creating a passageway extending from the first side of the microfeature workpiece to a second side of the microfeature workpiece opposite the first side; and forming a second workpiece contact to be fixed relative to the first workpiece contact by forming the second workpiece contact on the microfeature workpiece in a second plane generally parallel to and spaced apart from the first plane, wherein a bonding surface of the second workpiece contact is accessible to a wirebond extending through the passageway, and wherein a peripheral non-bonding surface of the second workpiece contact extends laterally outwardly from the passageway facing the second side of the microfeature workpiece.
