    Abstract: Methods and apparatus for processing a substrate are provided herein. For example, an RF power delivery compensation circuit comprises a first input configured to receive an RF forward power from an RF power source connected to a processing chamber and a second input configured to receive an RF delivered power from a matching network connected between the RF power source and the processing chamber. The RF power delivery compensation circuit calculates an RF forward power compensation factor based on the RF forward power and the RF delivered power for adjusting the RF forward power delivered to the processing chamber during operation.

    Abstract: A collimator that is biasable is provided. The ability to bias the collimator allows control of the electric field through which the sputter species pass. In some implementations of the present disclosure, a collimator that has a high effective aspect ratio while maintaining a low aspect ratio along the periphery of the collimator of the hexagonal array of the collimator is provided. In some implementations, a collimator with a steep entry edge in the hexagonal array is provided. It has been found that use of a steep entry edge in the collimator reduces deposition overhang and clogging of the cells of the hexagonal array. These various features lead to improve film uniformity and extend the life of the collimator and process kit.
