Abstract: A method of forming spacers for spacer-defined multiple pattering (SDMP), includes: depositing a pattern transfer film by PEALD on the entire patterned surface of a template using halogenated silane as a precursor and nitrogen as a reactant at a temperature of 200° C. or less, which pattern transfer film is a silicon nitride film; dry-etching the template using a fluorocarbon as an etchant, and thereby selectively removing a portion of the pattern transfer film formed on a top of a core material and a horizontal portion of the pattern transfer film while leaving the core material and a vertical portion of the pattern transfer film as a vertical spacer, wherein a top of the vertical spacer is substantially flat; and dry-etching the core material, whereby the template has a surface patterned by the vertical spacer on a underlying layer.

Abstract: Metallic layers can be selectively deposited on one surface of a substrate relative to a second surface of the substrate. In some embodiments, the metallic layers are selectively deposited on a first metallic surface relative to a second surface comprising silicon. In some embodiments the reaction chamber in which the selective deposition occurs may optionally be passivated prior to carrying out the selective deposition process. In some embodiments selectivity of above about 50% or even about 90% is achieved.
