    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.

    摘要: A method for forming a semiconductor device includes forming a partition line pattern and a partition pad pattern connected to an end part of the partition line pattern over the semiconductor substrate. Spacer insulation layers are formed at sidewalls of the partition line pattern and the partition pad pattern. A gap-filling layer is formed between the spacer insulation layers. A first cutting mask pattern is formed to expose a connecting part between the partition line pattern and the partition pad pattern. The partition line pattern and the gap-filling layer adjacent to the spacer insulation layer are removed using the first cutting mask pattern as a mask. A second cutting mask pattern including a first pattern and a second pattern are formed. The spacer insulation layer is removed using the second cutting mask pattern as a mask to form a gate trench in the substrate.

    摘要: A spacer is formed on side and top portions of a photoresist pattern after a mask process is performed so that the spacer may be used as an etching mask. The spacer is formed using a polymer deposition layer which is a low temperature oxide or nitride that can be deposited on side and top portions of the photoresist pattern at 75˜220° C. after the mask process is performed. A method for manufacturing a semiconductor device includes forming a bottom anti-reflection coating film on an etch-target layer, patterning a photoresist layer formed on the bottom anti-reflection coating film, forming an insulation layer on a patterned photoresist layer and the bottom anti-reflection coating film, etching back the insulation layer to form a spacer on sidewalls of the patterned photoresist layer, and etching the bottom anti-reflection coating film and the etching target layer exposed by the spacer to form a fine pattern.

    摘要: A method for forming a pattern of a semiconductor device using a spacer patterning process comprises coating a developable antireflection film over a substrate including a spacer pattern, coating a photoresist film over the antireflection film, and patterning the antireflection film and the photoresist film by an exposing and developing process to form an etching mask pattern. The etching mask pattern has an excellent profile. When a lower underlying layer is etched using the etching mask pattern, a sufficient etching margin can be secured, thereby obtaining a reliable semiconductor device.
