    摘要: A method and apparatus for adjusting an electric field of an electrochemical processing cell are provided. In one embodiment, a capacitive element is disposed in the processing solution. The strength, shape, or direction of the electric field in the processing solution may be modulated by charging and discharging the capacitive element in a controlled manner. Because the electric field is modulated with out passing a current from the capacitive element to the processing solution, electrochemical reactions do not occur on the interface of the capacitive element and the processing solution, thus, reduces complications caused by unwanted electrochemical reactions.

    摘要: Generally, the process includes depositing a barrier layer and seed layer on a feature formed in a dielectric layer, performing a grafting process, initiating a copper layer and then filing the feature by use of a bulk copper fill process. Copper features formed according to aspects described herein have desirable adhesion properties to a barrier and seed layers formed on a semiconductor substrate and demonstrate enhanced electromigration and stress migration results in the fabricated devices formed on the substrate.

    摘要: A method for electrolytically repairing a copper seed layer. The method includes positioning the seed layer in fluid communication with a low conductivity seed layer repair solution, wherein the low conductivity seed layer repair solution includes a copper concentration of less than about 20 g/l, a pH of less than about 4, a chlorine ion concentration of between about 20 ppm and about 100 ppm, and an additive organic surfactant configured to suppress a copper deposition rate in the concentration range of 200 ppm to 2000 ppm. The method further includes applying a seed layer repair bias configured to generate a current density of less than about 5 mA/cm2 across the seed layer and cleaning the repaired seed layer in pure water containing less than 1 ppm chloride ions.
