Abstract:
An electrical current conducting element comprising:at least a first oxidizable layer;said first oxidizable layer being significantly oxidized in a laterally oriented first region, said first region exhibiting high electrical resistance;said first oxidizable layer having a second region which is not significantly oxidized and having electrical resistance significantly lower than said first region;at least one semiconductor layer residing above a portion of said first oxidizable layer;top and bottom electrical contact disposed to communicate with said second region;interconnect metallization deposited above at least a portion of said semiconductor layer, and in electrical communication with said top electrical contact, said interconnect metallization for injecting electrical current through said second region; andat least one basin disposed in said electrical conducting element, said basin for allowing access to said first region by an oxidizing agent so as to oxidize said first region.
