A plasma processing apparatus includes a chamber having a space therein and configured to process a target object loaded into the space by plasma generated in the space; a gas supply unit configured to supply a processing gas into the space of the chamber; a high frequency antenna having a plurality of lines adjacent to each other and configured to generate the plasma in the space by an induced electric field generated in the space by a current flowing in the lines; and a plurality of holders configured to hold the lines of the high frequency antenna. The holders are arranged on the respective lines of the high frequency antenna such that the adjacent holders are spaced from each other by a gap of a predetermined distance or more.

A substrate processing system includes a first power source configured to supply plasma having a first power level, a second power source configured to supply plasma having a second power level greater than the first power level, and a controller configured to dose a process chamber with precursor. The first power level is sufficient to enhance adsorption of the precursor on a surface of a substrate and is insufficient to decompose the precursor that is adsorbed. The controller is further configured to remove a portion of the precursor that does not adsorb onto the substrate from the process chamber while the plasma having the first power level is being supplied and activate the precursor that is adsorbed using plasma having the second power level while the plasma having the first power level is still being supplied. The second power level is sufficient to decompose the precursor that is adsorbed.

There is provided a plasma processing device. The plasma processing device comprises: a chamber accommodating a stage on which a substrate is placed; an antenna disposed outside the chamber; a dielectric window disposed between the chamber and the antenna; a gas supply unit configured to supply a process gas into the chamber; a power supply unit configured to supply high-frequency power to the antenna to supply high-frequency waves into the chamber through the dielectric window and generate plasma from the process gas in the chamber; an electron generation unit configured to generate electrons in the chamber by excitation of the process gas supplied into the chamber; and a control device configured to control the power supply unit so as to supply the high-frequency power to the antenna simultaneously with the start of the excitation of the process gas by the electron generation unit or after the excitation of the process gas by the electron generation unit is started.

A method of manufacturing a metal oxide film includes injecting a reaction gas and metal precursors into a chamber, forming a first metal precursor film on a substrate in a plasma OFF state, forming a first sub-metal oxide film by oxidizing the first metal precursor film in a plasma ON state, and forming a second metal precursor film on the first sub-metal oxide film in the plasma OFF state, where the metal oxide film has an amorphous phase, a thickness of about 20 nanometer (nm) to about 130 nm, and a dielectric constant of about 10 to about 50.

A substrate processing tool capable of forming an carbon layer on a substrate by generating a plasma including carbon and non-carbon ions in a processing chamber, suspending the carbon and non-carbon ions in the processing chamber, removing mostly the suspended non-carbon ions from the processing chamber, and bombarding the substrate surface with mostly carbon ions. The one or more steps of the above sequence may be repeated until the carbon layer is of desired thickness.

A substrate processing apparatus of the present disclosure includes a processing container capable of being vacuum-exhausted, a lower electrode, and an upper electrode. A target substrate can be placed on the lower electrode. The upper electrode is disposed in the processing container so as to face the lower electrode. A substrate processing method of the present disclosure includes performing a first process on the target substrate using an AC voltage without using a DC pulse voltage, and performing a second process on the target substrate using the DC pulse voltage.

Provided herein are methods and related apparatus for depositing an ashable hard mask (AHM) on a substrate by pulsing a low frequency radio frequency component at a high power. Pulsing low frequency power may be used to increase the selectivity or reduce the stress of an AHM. The AHM may then be used to etch features into underlying layers of the substrate.
