Abstract

This invention is an antenna structure inducing plasma in a chamber with applied alternative power, comprising: a first antenna segment and a second antenna segment arranged based on a virtual central axis to have a first curvature radius and a second curvature radius respectively, the central axis crossing a first plane, and a first capacitive load electrically connecting the first antenna segment and the second antenna segment, wherein the first antenna segment extends from one end of the first capacitive load with the first curvature radius having a first length and the second antenna segment extends from other end of the first capacitive load with the second curvature radius having a second length, and wherein a sum of the first length and the second length is shorter than a circumference of the first curvature radius or the second curvature radius.
