1. A semiconductor component comprising:

  • a semiconductor die comprising a plurality of die contacts;

    a plurality of redistribution conductors on the die in electrical communication with the die contacts;

    a plurality of bumped contacts on the die in electrical communication with the redistribution conductors arranged in an area array;

    an electrically insulating layer on the die configured to electrically insulate the redistribution conductors; and

    a plurality of test contacts on the die comprising portions of the redistribution conductors and openings in the electrically insulating layer aligned with the portions;

    the test contacts configured such that each bumped contact of the area array has an associated test contact which can be physically and electrically contacted by a contact of an interconnect without interference from the bumped contacts for applying test signals to the die.
