  • Low impedance gold electrode, apparatus, method and electrolyte solution for fabricating the same
    Patent number: 8088262
    Abstract: Provided are a low impedance gold electrode, which has increased surface area, and can improve a bonding force with other materials, an apparatus for and a method of fabricating the low impedance gold electrode, and an electrolyte solution for use in the fabrication of the low impedance gold electrode. The gold electrode has a surface roughness that is increased through electrolysis using an acid electrolyte solution, has an impedance that is less than 1/10 of an impedance before the electrolysis and is higher than 0? when the low impedance gold electrode is disposed in the acid electrolyte solution or another electrolyte solution, and has a single-layered structure whose thickness is less than that before the electrolysis.
