  • Patent number: 10644025
    Abstract: A method of processing a substrate by omitting a photolithographic process is disclosed. The method includes forming at least one layer on a stepped structure having an upper surface, a lower surface, and a side surface that connects the upper surface to the lower surface, selectively densifying portions of the at least one layer respectively on the upper surface and the lower surface via asymmetric plasma application, and performing an isotropic etching process on the at least one layer. During the isotropic etching process, the portion of the at least one layer formed on the upper surface is separated from the portion of the at least one layer formed on the lower surface.

  • Patent number: 10381226
    Abstract: A method of processing a substrate to enable selective doping without a photolithography process is provided. The method includes forming a diffusion barrier on the substrate having a patterned structure using plasma deposition method, removing the diffusion barrier except for part of the diffusion barrier using wet etching, forming a diffusion source layer on the patterned structure and the part of the diffusion barrier, and applying energy to the diffusion source layer.
