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: A method for forming a semiconductor device is disclosed. A method for forming a semiconductor device includes forming a first sacrificial hard mask layer over a semiconductor substrate including an etch layer, forming a first spacer over the first sacrificial hard mask layer, forming a first sacrificial hard mask pattern by etching the first sacrificial hard mask layer using the first spacer as an etch mask, forming a second spacer at both sidewalls of the first sacrificial hard mask pattern, partially isolating the second spacer, and forming a pad pattern over the second spacer. As a result, a line-and-space pattern such as a control gate of the NAND flash memory and a pad portion coupled to a drain contact in an X-decoder of a peripheral circuit region can be easily implemented.
