    Abstract: A method for trimming a carbon-containing film includes: (i) providing a substrate having a carbon-containing film formed thereon; (ii) supplying a trimming gas and a rare gas to the reaction space, which trimming gas includes an oxygen-containing gas; and (iii) applying RF power between the electrodes to generate a plasma using the trimming gas and the rare gas and to thereby trim the carbon-containing film while controlling a trimming rate at 55 nm/min or less as a function of at least one parameter selected from the group consisting of a flow rate of an oxygen-containing gas, a flow rate of nitrogen-containing gas to be added to the oxygen-containing gas, pressure in the reaction space, RF power, a duty cycle of RF power, a distance between the electrodes, and a temperature of a susceptor on which the substrate is placed.

    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.

    Abstract: A method for controlling in-plane uniformity of a substrate processed by plasma-assisted process in a reactor, includes: supplying a principal gas to a reaction space, and discharging radially the principal gas from the reaction space through an annular duct; and supplying an secondary gas to the reaction space from an area in close proximity to an outer periphery of a susceptor, outside an outer circumference of the substrate as viewed from above, so as to flow at least partially in an inward direction passing the outer circumference of the substrate, reversing the direction of the secondary gas to flow toward the annular duct in a vicinity of the outer circumference of the substrate, and discharging radially the secondary gas together with the principal gas from the reaction space through the annular duct.
