  • Publication number: 20230112490
    Abstract: In a method of depositing a silicon oxide film using bis(diethylamino)silane (BDEAS) on a substrate in a reaction space by plasma-enhanced atomic layer deposition (PEALD), each repeating deposition cycle of PEALD includes steps of: (i) adsorbing BDEAS on the substrate placed on a susceptor having a temperature of higher than 400° C. in an atmosphere substantially suppressing thermal decomposition of BDEAS in the reaction space; and (ii) exposing the substrate on which BDEAS is adsorbed to an oxygen plasma in the atmosphere in the reaction space, thereby depositing a monolayer or sublayer of silicon oxide.

  • Publication number: 20220319831
    Abstract: Methods of forming treated silicon nitride layers are disclosed. Exemplary methods include forming a silicon nitride layer overlying the substrate by providing a silicon precursor to the reaction chamber for a silicon precursor pulse period, providing a nitrogen reactant to the reaction chamber for a reactant pulse period, during a deposition process applying a first plasma power having a first frequency for a first plasma power period, and during a treatment step, applying a second plasma power having a second frequency for a second plasma power period.

  • Patent number: 10770257
    Abstract: Examples of a substrate processing method include subjecting a substrate placed on a susceptor to plasma processing, applying power to an RF electrode facing the susceptor for only a predetermined static electricity removal time to generate plasma, thereby reducing an amount of charge of the substrate, measuring a self-bias voltage of the RF electrode while susceptor pins are made to protrude from a top surface of the susceptor and lift up the substrate, and by a controller, shortening the static electricity removal time when the self-bias voltage has a positive value, and lengthening the static electricity removal time when the self-bias voltage has a negative value.

  • Patent number: 10707073
    Abstract: Examples of a film forming method includes repeating first processing and second processing in this order a plurality of times, wherein the first processing supplies material-1 having one silicon atom per molecule onto a substrate, and then generates plasma while reactant gas is introduced, thereby forming a silicon oxide film on the substrate, and the second processing provides material-2 having two or more silicon atoms per molecule onto the substrate, and then generates plasma while no reactant gas is introduced, thereby forming a double silicon compound on the substrate.
