Abstract:
Embodiments of the disclosure generally provide multi-layer dielectric stack configurations that are resistant to plasma damage. Methods are disclosed for the deposition of thin protective low dielectric constant layers upon bulk low dielectric constant layers to create the layer stack. As a result, the dielectric constant of the multi-layer stack is unchanged during and after plasma processing.
