Abstract:
1. A plasma generating apparatus comprising: a first electrode; a second electrode structure located in front of the first electrode; an insulating layer interposed between the first electrode and the second electrode structure, wherein the insulating layer interposed between the first electrode and the second electrode structure completely fills the space between the first electrode and the second electrode structure, wherein the second electrode structure has a plurality of second electrode portions defining gap portions therebetween, the width of the gap portions being w, the second electrode portions each having a forward surface and the gap portions each having a forward surface, the height difference between the forward surface of each second electrode portion and the forward surfaces of the adjacent gap portions being h, and wherein h is at most 0.1 mm and the ratio w/h is at least 10, and wherein the second electrode structure is covered with a second insulating layer.
