    Abstract: Provided is a flow rate control method, including: supplying fluid from a valve to a first sensor; measuring, by the first sensor, a first temperature of the fluid, and heating the fluid; measuring, by a second sensor, a second temperature of the heated fluid, and determining, by a controller, a first flow rate of the fluid based on comparison between the first temperature and the second temperature; supplying the fluid to a chamber and supplying an ignition voltage to the chamber through a radio frequency (RF) power source; measuring, by a third sensor, the ignition voltage; comparing, by the controller, the ignition voltage and a reference voltage to determine a second flow rate of the fluid; and controlling a supply of the fluid from the valve based on at least one of the first flow rate and or the second flow rate.

    Abstract: A gas supply for a layer deposition apparatus including a plurality of charge distribution lines connected to a first gas supply source and a plurality of gas filling tanks respectively connected to the charge distribution lines is disclosed. Each of the gas filling tanks may be pressurized with a first gas from the first gas supply source, and a gas supply line connected to a second gas supply source. The apparatus may include a multi-dosing valve assembly connected to outlet portions of the gas filling tanks and configured to supply, sequentially, the first gas from the gas filling tanks to a process chamber. The multi-dosing valve assembly may include a flow path block having a main supply line connected to the process chamber and a backflow prevention valve block fastened to the flow path block and having an opening/closing valve therein.
