Abstract
Methods of depositing a conformal carbon-containing spacer layer are described. Exemplary processing methods may include flowing a first precursor over a patterned surface and a substrate to form a first portion of an initial carbon-containing film on the structure. A second precursor may then be flowed over the substrate to react with the first portion of the initial carbon-containing film. The methods may include etching the substrate to remove a portion of the carbon-containing film and expose a top surface of the patterned surface and expose the substrate between the patterned surfaces. The patterned surface may be an EUV photoresist pattern, and the carbon-containing film may be formed on the sidewall to reduce the critical dimension (CD). The carbon-containing film may act as an etch protection layer for the sidewall of the nanostructures. When no etch is performed, the carbon-containing film may act as a liner material.
