    摘要: A pattern formation method comprises forming a material layer on a substrate, forming an amorphous carbon layer on the material layer, forming an anti-reflective layer on the amorphous carbon layer, forming a silicon photoresist layer on the anti-reflective layer, forming a silicon photoresist layer pattern by patterning the silicon photoresist layer, etching the anti-reflective layer and the amorphous carbon layer using the silicon photoresist layer pattern as an etch mask to form an amorphous carbon layer pattern, and etching the material layer using the amorphous carbon layer pattern as an etch mask to form a pattern in the material layer.

    摘要: A method of forming a pattern comprises the steps of stacking an inorganic hard mask layer, an organic mask layer, and an anti-reflecting layer on a substrate where a lower layer is formed, forming a photoresist pattern containing silicon on the anti-reflecting layer, performing an O2 plasma ashing to form a conformal layer of an oxide glass on the photoresist pattern containing silicon and to dry etch the anti-reflecting layer and the organic mask layer to form an anti-reflecting pattern and an organic mask pattern, removing the photoresist pattern, the anti-reflecting pattern, and the organic mask pattern, and etching the lower layer using a pattern of the inorganic hard mask layer as an etch mask.

    摘要: Provided are a mask pattern including a silicon-containing self-assembled molecular layer, a method of forming the same, and a method of fabricating a semiconductor device. The mask pattern includes a resist pattern formed on a semiconductor substrate and the self-assembled molecular layer formed on the resist pattern. The self-assembled molecular layer has a silica network formed by a sol-gel reaction. To form the mask pattern, first, the resist pattern is formed with openings on an underlayer covering the substrate to expose the underlayer to a first width. Then, the self-assembled molecular layer is selectively formed only on a surface of the resist pattern to expose the underlayer to a second width smaller than the first width. The underlayer is etched by using the resist pattern and the self-assembled molecular layer as an etching mask to obtain a fine pattern.
