Method for forming spacers using silicon nitride film for spacer-defined multiple patterning
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...

| description | 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. |
