Abstract:
1. A catalytic enhanced chemical vapor deposition apparatus comprising: a deposition chamber; a shower head for storing a deposition source gas, the showerhead including at least two electrodes; a plurality of gas nozzles formed on the shower head and coupled to the deposition chamber for spraying the deposition source gas into inside of the deposition chamber; and a filament formed on the shower head and disposed between the plurality of gas nozzles and a substrate on which a deposition is made, the filament being coupled to the electrodes, the filament formed into a pattern, the filament including a plurality of sub-filaments, each of the sub-filaments forming a straight line, the sub-filaments parallel to each other and formed such that a distance between the nearest sub-filaments formed around an edge part of the pattern is narrower than the distance between the nearest sub-filaments formed an central part of the pattern.
