Patent ID: 8652342

Claim:
A method of fabricating a semiconductor device using a semiconductor fabrication apparatus having lower and upper bodies facing each other in which, toward a lower side from an upper side of the semiconductor fabrication apparatus, the upper body has gas tubes, an upper electrode and a gas induction housing, and the lower body has middle and lower electrodes, and performing semiconductor etching and deposition processes, the method comprising: preparing a semiconductor substrate; mounting the semiconductor substrate on the middle electrode; injecting etching process gases between the upper and lower electrodes; performing the semiconductor etching process on the semiconductor substrate by setting an etching power recipe to the upper, middle and lower electrodes; removing the etching process gases from the upper and lower electrodes after performance of the semiconductor etching process; injecting deposition process gases between the upper and lower electrodes; and performing the semiconductor deposition process onto the semiconductor substrate by setting a deposition power recipe to the upper, middle and lower electrodes, wherein the etching and deposition process gases are converted into plasma, respectively, corresponding thereto according to the etching and deposition recipes, and the plasma is formed along an edge of the semiconductor substrate, during the semiconductor etching and deposition processes, wherein a diameter of the lower electrode is larger than a diameter of the middle electrode, a diameter of the upper electrode is larger than a diameter of the gas induction housing, and a diameter of the gas induction housing is different from that of the middle electrode.
