Abstract

A method and system of modifying a substrate using a plasma are described comprising providing a first electrode and a second electrode; arranging the substrate such that a portion of the substrate is between the electrodes; supplying a voltage to at least one of the electrodes so as to create a plasma discharge between the electrodes which contacts at least said portion of the substrate, moving either the substrate and/or said second electrode such that said substrate and said second electrode are being linearly displaced relative to each other along an axis of linear displacement during said movement; and wherein said second electrode is arranged relative to said axis of linear displacement such that said linear movement causes a first section of the portion of substrate to have a greater residence time between the electrodes during said linear displacement than a second section of said portion of the substrate. A method and system of modifying a substrate using a plasma is also described comprising providing a first electrode and a second electrode; arranging the substrate such that a portion of the substrate is between the electrodes; supplying a voltage to at least one of the electrodes so as to create a plasma discharge between the electrodes which contacts at least said portion of the substrate, moving either the substrate and/or said second electrode such that said substrate and said second electrode are being linearly displaced relative to each other along an axis of linear displacement during said movement; and further comprising the step of rotating either the substrate or said second electrode about an axis of rotation during said relative linear displacement along said axis, so that a first section of the portion of substrate has a greater residence time between the electrodes than a second section of said portion of substrate.
