To provide a plasma processing device, a plasma processing method and a method of manufacturing electronic devices capable of performing high-speed processing as well as using the plasma stably. In an inductively-coupled plasma torch unit, a coil, a first ceramic block and a second ceramic block are arranged in parallel, and a long chamber has an annular shape. Plasma generated in the chamber is ejected from an opening in the chamber toward a substrate. The substrate is processed by moving the long chamber and the substrate mounting table relatively in a direction perpendicular to a longitudinal direction of the opening. A discharge suppression gas is introduced into a space between the inductively-coupled plasma torch unit and the substrate inside the chamber through a discharge suppression gas supply hole, thereby generating long plasma stably. |
