Abstract:
1. A thin film deposition apparatus having a reaction chamber for forming a thin film on a plurality of substrates rested on a susceptor, the apparatus comprising: a gas supply means for supplying a plurality of gases to the inside of the reaction chamber from the outside, the gases including a reaction gas; a gas distribution means for distributing and spraying the gases supplied from the gas supply means so as to conform to the purpose of a process; a gas retaining means for partitionally accommodating and concurrently retaining the gases distributed from the gas distribution means, the gas retaining means comprising: a rotation driving means for rotating selectively one of the gas retaining means and the susceptor such that the gases concurrently retained in the respective reaction cells are exposed to the substrates in sequence; and a gas exhaust means for pumping the gases retained by the gas retaining means to the outside of the reaction chamber; wherein the gas distribution means further comprises a fixing means for fixing the as retaining means; a distribution main body inserted into the central portion of the upper plate and closely contacting the respective partition walls; a gasinlet ports formed in the distribution main bodysuch that gases supplied from the gas supply means are individually introduced; a distribution chamber fluid-communicated with the gas inlet ports and having a desired space formed therein for partitionally accommodating the respective gases; and a plurality of lateral spray ports formed in the later face of the distribution main body such that the gases accommodated in the distribution chamber are sprayed to the lateral faces of the respective reaction cells.
