Abstract:
1. 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; and a bending type antenna structure including a plurality of bending type linear antennas, each of the bending type linear antennas including a first linear portion, a second linear portion and a bended portion, the bending type linear antennas being arranged horizontally in parallel with the substrate to pass through the reaction chamber inside the reaction chamber, and the bending type linear antennas being spaced apart from each other, wherein the first and second linear portions of each of the bending type linear antennas are placed inside the reaction chamber, the first linear portion of each of the bending type linear antennas is surrounded by a first protecting tube, the second linear portion of each of the bending type linear antennas is surrounded by a second protecting tube, all of first ends of the bending type linear antennas are protruded out of a first side of the reaction chamber and are coupled to a radio frequency power, all of second ends of the bending type linear antennas are protruded out of the first side of the reaction chamber and are coupled to a ground, and the bended portion of each of the bending type linear antennas is protruded out of a second side of the reaction chamber, and wherein each of the first ends and each of the second ends of the bending type linear antennas are alternatively arranged with respect to one another such that a first end of one of the bending type linear antennas is arranged adjacent to a second end of another of the bending type linear antennas that is adjacent to the one of the bending type linear antennas.
