1. A method of processing a substrate for use in a nanoscale molecular device, comprising the steps of:
a. providing a substrate of ferroelectric material having a first polarization distribution;
b. establishing on said substrate at least one localized region having a second polarization distribution oriented differently from said first polarization distribution by the influence of an energy field applied to said at least one localized region;
c. exposing said substrate to ions of an electrically conductive metal, said metal ions being deposited selectively at said at least one localized region due to interaction between said metal ions and said at least one localized region; and
d. converting said deposited metal ions to elemental metal at said at least one localized region.
