The aspect ratios are obtained by dividing lengths in the vertical direction of the inner walls of the antennas by lengths in the direction parallel with the inner walls. Induced electric fields generated in the vertical direction on the inner walls of the antennas by applying a high-frequency voltage to the antennas 16 accelerate plasma electrons in the direction, and increase a plasma density. Accordingly, the plasma density in the vicinity of the center of the substrate base 14, in which the plasma density is made lower than peripheries in conventional devices, is increased, and the uniformity of the plasma density is improved.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
