  • Patent number: 11830738
    Abstract: In a method for forming a barrier layer, the barrier layer is formed on a base layer having a three-dimensional structure before a dopant-containing layer is formed on the base layer. At this time, at least one of a film thickness, a film quality, and a film type of the barrier layer is controlled in a height direction of the three-dimensional structure by using an atomic layer deposition (ALD) process.

  • 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.
