    摘要: A method for forming a fine pattern of a semiconductor device includes forming a deposition film over a substrate having an underlying layer. The deposition film includes first, second, and third mask films. The method also includes forming a photoresist pattern over the third mask film, patterning the third mask film to form a deposition pattern, and forming an amorphous carbon pattern at sidewalls of the deposition pattern. The method further includes filling a spin-on-carbon layer over the deposition pattern and the amorphous carbon pattern, polishing the spin-on-carbon layer, the amorphous carbon pattern, and the photoresist pattern to expose the third mask pattern, and performing an etching process to expose the first mask film with the amorphous carbon pattern as an etching mask. The etching process removes the third mask pattern and the exposed second mask pattern. The method also includes removing the spin-on-carbon layer and the amorphous carbon pattern, and forming a first mask pattern with the second mask pattern as an etching mask.

    摘要: A method for forming a pattern of a semiconductor device is provided. Specifically, in a method for manufacturing a NAND flash memory device using a spacer patterning process, a dummy pattern, which is not used in an actual device operation, is additionally formed in a peripheral circuit region when a photoresist pattern for forming a string pattern is formed in a cell region. As a result, the edge photoresist pattern is prevented from being bent, and a critical dimension difference between the center region and the edge region of the photoresist pattern lo is not generated, thereby improving a margin of DOF to obtain a reliable semiconductor device.

    摘要: Disclosed herein are photoresist cleaning solutions useful for cleaning a semiconductor substrate in the last step of a developing step when photoresist patterns are formed. Also disclosed herein are methods for forming photoresist patterns using the solutions. The cleaning solutions of the present invention include H2O as a primary component, a surfactant as an additive, and optionally an alcohol compound. The cleaning solution of the present invention has lower surface tension than that of distilled water which has been used for conventional cleaning solutions, thereby improving resistance to pattern collapse and stabilizing the photoresist pattern formation.
