A coater having a substrate cleaning device is disclosed. The substrate cleaning device comprises an ion gun (i.e., an ion source) that is positioned beneath a path of substrate travel (e.g., beneath a substrate support) extending through the coater and that is adapted for treating a bottom major surface of a substrate. Certain embodiments involve an upward coating apparatus that is further along the path of substrate travel than the substrate cleaning device.
