The method includes flowing a surface modification gas into a plasma processing chamber of a 212 plasma processing system, igniting a plasma in the plasma processing chamber to 1 7 initiate a surface modification process for a layer formed on a substrate, and acquir- ing optical emission spectra from an optical emission spectroscopy system attached k 214 to the plasma processing chamber, during the surface modification process for the layer. For one embodiment, the method includes altering at least one parameter of the surface modification process based on the acquired optical emission spectra. For one embodiment, the acquired optical emission spectra can include an intensity of a spectral line, a slope of a spectral line, or both to enable endpoint control of the surface modification process. Additional methods and related systems are also dis- closed.
