摘要: Carbon-containing patterns are formed on an etch target layer, side surfaces of the carbon-containing patterns are treated by a hydrophilic process, poly-crystalline silicon spacers are formed on the side surfaces of the carbon-containing patterns after the hydrophilic process has been performed, and the etch target layer is patterned using the poly-crystalline silicon spacers as an etch mask.
