Patent ID: 8293069

Claim:
An inductively coupled plasma processing apparatus for a large area processing, the inductively coupled plasma processing apparatus comprising: a reaction chamber in which a substrate is loaded; a double comb type antenna structure including a plurality of first linear antennas and a plurality of second linear antennas separately arranged horizontally to pass through the reaction chamber inside the reaction chamber, wherein the first and second linear antenna are alternately aligned with each other, first ends of the first linear antennas are protruded out of the reaction chamber and coupled to each other so as to be coupled to a first induced RF power, and first ends of the second linear antennas are protruded out of the reaction chamber in opposition to the first ends of the first linear antennas and coupled to each other so as to be coupled to a second induced RF power, wherein second ends of the first linear antennas are protruded out of the reaction chamber in opposition to the first ends of the first linear antennas and are grounded, and second ends of the second linear antennas are protruded out of the reaction chamber in opposition to the first ends of the second linear antennas and are grounded, and wherein the first linear antennas has a plurality of first antenna rods which are connected to each other, the second linear antennas has a plurality of second antenna rods which are connected to each other, and each of the second antenna rods of the second linear antenna is inserted between the first rods of the first linear antenna.
