From The Free On-line Dictionary of Computing (27 SEP 03) [foldoc]:

  substrate
       
           The body or base layer of an {integrated circuit},
          onto which other layers are deposited to form the circuit.
          The substrate is usually Silicon, though Sapphire is used for
          certain applications, particularly military, where radiation
          resistance is important.  The substrate is originally part of
          the {wafer} from which the {die} is cut.  It is used as the
          electrical {ground} for the circuit.
