A microelectronic package including a microelectronic die disposed within an opening in a microelectronic packaging core, wherein an encapsulation material is disposed within portions of the opening not occupied by the microelectronic die. The interface apparatus comprises passive detectable devices trackable for position by the tracking system. Through the process, computer readable definitions of an alternating aperture, dark field phase shift mask and of a complimentary mask are generated. A web interface may also be provided that allows a user to access files in the datastore through the use of a web browser. The certain voltage is based on the reference voltage.
