Abstract

A microwave plasma generating apparatus radiates a microwave to a source gas to produce a plasma. A plurality of spaced fins are disposed in a path of travel of the microwave, from the microwave guide to an area of origin of the plasma within the plasma generating chamber to lie in a direction perpendicular to the direction of an electric field of the microwave, for the purpose of locking the position at which the plasma has been produced.
