Claim:
1. A ZnO film production system, comprising: an installation base configured to support a substrate on which a ZnO film is to be formed; a reaction container configured to accommodate the installation base; a first raw material storing part configured to communicate with an interior of the reaction container and to store a solid first raw material which contains Zn; a second raw material storing part configured to communicate with the interior of the reaction container and to store a solid raw second material which contains Zn; heating units configured to heat the installation base, the first and the second raw material storing parts; a chlorine gas supply source configured to supply a chlorine gas to at least the first raw material storing part; an oxygen gas supply source configured to supply an oxygen gas into the reaction container; and a control device, wherein the control device is configured to control the heating units such that a temperature T the control device is configured to supply a flow rate of the chlorine gas supplied from the chlorine gas supply source to the first raw material storing part, the control device is configured to supply a flow rate of the oxygen gas supplied from the oxygen gas supply source into the reaction container, and the first and the second raw material storing parts are arranged adjacent to one another such that the first and the second raw material storing parts are configured to allow the chlorine gas first to pass through the first raw material storing part and next pass through the second raw material storing part before reaching the substrate, and the first and the second raw material storing parts have a bottom surface inclined such that a depth of the first and the second raw material storing parts grows larger toward a side of the second raw material storing part having a gas injection port, the depth of the first and the second raw material storing parts is measured from a horizontal surface positioned above the bottom surface of the first and the second raw material storing parts.
