Abstract

At least one device (1) and at least one method for removing a layer (22) from a substrate (20) by applying a pulsed high voltage are disclosed. For this purpose, at least one pressure plasma burner (2) operating at atmospheric-pressure, a high-voltage source (3), and a supply of process gas (4) are required. Via a gas line (10), the supply of process gas (4) is connected with an inlet (6) of the plasma burner (2). The plasma burner (2) has a nozzle (7) through which a plasma jet (8) emerges. The high-voltage source (3) is configured such that a pulsed high voltage is applied between the plasma burner (2) and an electrically conductive element (11), which pulsed high voltage reaches a breakdown voltage in the region (29) of the conductive element (11).
