Abstract:
A method and apparatus for dry etching pure Cu and Cu-containing layers for manufacturing integrated circuits. The invention uses a directional beam of O-atoms with high kinetic energy to oxidize the Cu and Cu-containing layers, and organic compound etching reagents that react with the oxidized Cu to form volatile Cu-containing etch products. The invention allows for low-temperature, anisotropic etching of pure Cu and Cu-containing layers in accordance with a patterned hard mask or photoresist.

A substrate (1) on which metal layers (2A, 2B) are disposed with a gap therebetween is immersed in an electroless plating solution in which a reducing agent and surfactant are mixed into an electrolyte containing metal ions. The metal ions are reduced by the reducing agent, and while the metal is deposited on the metal layers (2A, 2B), the surfactant adheres to the surface of the metal, and electrodes (4A, 4B), wherein the gap length is controlled to a nanometer size, are formed. Thus, a method for fabricating an electrode structure having a nanogap gap length such that the variations in gap length can be controlled, an electrode structure having a nanogap length in which variations in gap length are suppressed using this fabrication method, and a nanodevice provided with the same are provided.
