DYNAMIC WAFER LEVELING/TILTING/SWIVELING DURING A CHEMICAL VAPOR DEPOSITION PROCESS

The implementations described herein generally relate to the dynamic, real-time control of the process spacing between a substrate support and a gas distribution medium during a deposition process. Multiple dimensional degrees of freedom are utilized to change the angle and spacing of the substrate plane with respect to the gas distributing medium at any time during the deposition process. As such, the substrate and/or substrate support may be leveled, tilted, swiveled, wobbled, and/or moved during the deposition process to achieve improved film uniformity. Furthermore, the independent tuning of each layer may be had due to continuous variations in the leveling of the substrate plane with respect to the showerhead to average effective deposition on the substrate, thus improving overall stack deposition performance.
