Abstract
Provided is a thin film deposition process that allows high-precision control of the in-plane distribution of a thin film being deposited on a substrate. The process is a process of depositing a thin film on a substrate in a chamber by atomic layer deposition (ALD) which includes repeating a deposition cycle to deposit the thin film on the substrate. The deposition cycle includes the steps of: feeding a reactive gas and a carrier gas to the chamber and feeding a source gas at a reduced concentration to the chamber to allow the source gas to adsorb on the substrate; feeding the reactive gas and the source gas to the chamber to allow the source gas to adsorb on the substrate; feeding the reactive gas and the carrier gas to the chamber to purge, from the chamber, the source gas not adsorbing on the substrate; applying RF power to the chamber to turn the reactive gas into a plasma so that the source gas activated by the plasma is allowed to come into contact with a surface of the substrate; and feeding the reactive gas and the carrier gas to the chamber to purge, from the chamber, the source gas remaining unreacted and the reactive gas.
