Abstract:
1. A deposition system which supplies a source gas and a purge gas alternately for deposition, comprising: a deposition chamber; a substrate holding unit which holds a substrate in the deposition chamber; a source gas supply unit which supplies the source gas to the deposition chamber; a reactive gas supply unit which supplies a reactive gas to the deposition chamber; a purge gas supply unit which supplies the purge gas to the deposition chamber; an exhaust unit which exhausts the source gas, the reactive gas, and the purge gas from the deposition chamber; a first heating unit which heats the substrate arranged in the deposition chamber to maintain the same to a predetermined temperature; a second heating unit which heats the substrate arranged in the deposition chamber rapidly; an annealing gas introducing unit which introduces an annealing gas into the deposition chamber; and a partition plate positioned lower than an inlet of the annealing gas introducing unit and higher than inlets of the reactive gas supply unit, the source gas supply unit, and the purge gas supply unit, the partition plate having a single center opening; wherein the first heating unit is a heater formed on a substrate holding surface of the substrate holding unit; the substrate holding unit has a moving mechanism which moves the substrate in position so that the distance between the substrate and the second heating unit can be adjusted by an operation from outside the deposition chamber without opening the deposition chamber, and the substrate holding unit and the partition plate are structure such that the substrate holding unit contacts the partition plate when the substrate holding unit is in a raised position; and the substrate holding unit and the partition plate are structured such that the substrate is accessible to the annealing gas through the center opening in the partition plate when the substrate holding unit is in the raised position.
