摘要: Methods and apparatus for protecting parts of a process chamber from thermal cycling effects of deposited materials. In some embodiments, a method of protecting the part of the process chamber includes wet etching the part with a weak alkali or acid, cleaning the part by bead blasting, coating at least a portion of a surface of the part with a stress relief layer. The stress relief layer forms a continuous layer that is approximately 50 microns to approximately 250 microns thick and is configured to preserve a structural integrity of the part from the thermal cycling of aluminum deposited on the part. The method may also include wet cleaning of the part with a heated deionized water rinse after formation of the stress relief layer.

摘要: Methods for forming layers on a substrate having a feature are provided herein. In some embodiments, a method for forming layers on a substrate having a features may include depositing a copper layer within the feature, wherein a thickness of the copper layer disposed on upper corners of an opening of the feature and on an upper portion of a sidewall proximate the upper corners of the feature is greater than the thickness of the copper layer disposed on a lower portion of a sidewall of the feature proximate a bottom of the feature; and exposing the substrate to a plasma formed from a process gas comprising hydrogen (H2) gas to selectively etch the copper layer proximate the upper corners of the opening and the upper portion of the sidewall proximate the upper corners, without substantially etching the copper layer proximate the lower portion of the sidewall proximate the bottom of the feature.
