Patent ID: 8344438

Claim:
An electrode of an integrated circuit, comprising: a first metallic layer comprising a first metallic material selected of at least one of ruthenium, ruthenium oxide, iridium, iridium oxide, platinum, palladium, gold, silver, rhenium, and rhodium; an electrically conductive metal compound layer deposited on the first metallic layer, the electrically conductive metal compound layer selected from an electrically conductive nitride of a second metallic material, an electrically conductive oxide of a second metallic material, and an electrically conductive oxynitride of a second metallic material; a second metallic layer comprising the first metallic material deposited on the electrically conductive metal compound layer, so that a path of low resistance is provided from the first metallic layer to the second metallic layer through the metal compound layer; a second electrically conductive metal compound layer deposited on the second metallic layer, the electrically conductive metal compound layer selected from an electrically conductive nitride of the second metallic material, an electrically conductive oxide of the second metallic material, and an electrically conductive oxynitride of the second metallic material; and a third metallic layer comprising the first metallic material deposited on the second electrically conductive metal compound layer.
