Abstract
Methods and systems for depositing material layers with gap variation between film deposition operations. One method includes depositing a material layer over a substrate. The depositing is performed in a plasma chamber having a bottom electrode and a top electrode. The method includes providing a substrate over the bottom electrode in the plasma chamber. The method sets a first gap between the bottom and top electrodes and performs plasma deposition to deposit a first film of the material layer over the substrate while the first gap is set between the bottom and top electrodes. The method then sets a second gap between the bottom a top electrodes and performs plasma deposition to deposit a second film of the material layer over the substrate while the second gap is set between the bottom and top electrodes.
