Abstract: In a plasma deposition method, a substrate is loaded onto a substrate stage within a chamber. A first plasma is generated at a region separated from the substrate by a first distance. A first process gas is supplied to the first plasma region to perform a pre-treatment process on the substrate. A second plasma is generated at a region separated from the substrate by a second distance different from the first distance. A second process gas is supplied to the second plasma region to perform a deposition process on the substrate.
