    Abstract: A patterning method includes the following steps. A layout pattern is provided to a computer system. The layout pattern includes stripe patterns, and each of the stripe patterns extends in a first direction. Mandrel patterns are formed corresponding to a part of the stripe patterns. Each of the mandrel patterns extends in the first direction. A modification is performed to the mandrel patterns for elongating at least a part of the mandrel patterns in the first direction. Ends of the mandrel patterns in the first direction are aligned in a second direction perpendicular to the first direction after the modification. The mandrel patterns are outputted to a photomask after the modification. A photolithography process using the photomask is performed for forming a patterned structure on a substrate. By performing the modification to the mandrel patterns, design flexibility of the layout pattern corresponding to the patterning method may be enhanced.

    Abstract: A method for forming patterns for semiconductor device includes following steps. A substrate including a hard mask layer and a sacrificial layer is provided. A plurality of mandrel patterns are formed on the substrate. A spacer is respectively formed on sidewalls of the mandrel patterns. The mandrel patterns are removed to form a plurality of spacer patterns directly formed on the sacrificial layer. A plurality of first blocking layers are formed in the sacrificial layer after forming the spacer patterns. A plurality of second blocking layers exposing at least a portion of the sacrificial layer and at least a portion of the first blocking layers are formed on the substrate. The sacrificial layer and the hard mask layer are etched with the spacer patterns, the first blocking layers, and the second blocking layers serving as etching masks to form a patterned hard mask layer on the substrate.

    Abstract: A method for forming patterns for semiconductor device includes following steps. A substrate is provided. The substrate includes a hard mask layer and a sacrificial layer formed thereon. A plurality of spacer patterns parallel with each other are formed on the substrate. A plurality of first blocking layers are formed in the sacrificial layer after forming the spacer patterns. A plurality of second blocking layers exposing at least a portion of the sacrificial layer and at least a portion the first blocking layer are formed on the substrate after forming the first blocking layer. Next, the sacrificial layer and the hard mask layer are etched with the spacer patterns, the first blocking layers and the second blocking layer being used as etching masks to form a patterned hard mask layer on the substrate.
