A method for depositing a film layer on a substrate incorporates ion flux control to alter sputtering atom trajectories. A method may include flowing argon gas around a periphery of the substrate with a surface of the substrate having a plurality of structures with sidewalls and an edge region containing edge structures near the periphery of the substrate, forming a plasma to ionize the argon gas to form Ar+ ion flux to induce sputtering of aluminum to generate aluminum atoms for deposition on the substrate, generating an AC bias on the substrate to increase the Ar+ ion flux density at the edge region of the substrate to alter aluminum atom trajectories striking the edge region, and heating the substrate to increase mobility of the aluminum atoms deposited on the edge structures.

Methods and apparatus for depositing aluminum by physical vapor deposition (PVD) with controlled cooling

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.
