    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 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.

    摘要: A method for aligning wafer includes selecting a nun-defective wafer alignment mark of a first wafer loaded in an exposure apparatus, and storing non-defective wafer alignment marks as a gray level reference image. A plurality of wafer alignment marks of a loaded second wafer are stored. Each of the plurality of wafer alignment mark images of the second wafer are respectively compared with the reference image of the first wafer pixel by pixel to obtain matching value for each of the plurality of the wafer alignment mark images. Each of the plurality of values of the matching values are compared with a set minimum value. The wafer alignment mark image having the matching value smaller than the minimum value with the reference image is replaced. The alignment information for an underlying layer using a wafer alignment information for an underlying layer using a wafer alignment sensor is obtained.
