    摘要: A method of patterning a structure in a thin film on a substrate is described. A film stack on the substrate includes the thin film on the substrate, a developable anti-reflective coating (ARC) layer on the thin film, and a first photo-resist layer on the developable ARC layer. The first photo-resist layer and the developable ARC layer are imaged with a first image pattern and developed to form the first image pattern in the first photo-resist layer and the developable ARC layer. Thereafter, the first photo-resist layer is removed, and the developable ARC layer is modified by thermal treatment. A second photo-resist layer is then formed on the modified ARC layer, and the second photo-resist layer is imaged with a second image pattern and developed to form the second image pattern in the second photo-resist layer. The first and second image patterns are then transferred to the thin film.

    摘要: A method of double patterning a thin film is described. The method comprises forming a thin film to be patterned on a substrate, forming an anti-reflective coating (ARC) layer on the thin film, and forming a mask layer on the ARC layer. Thereafter, the mask layer is patterned to form a first pattern and a second pattern therein, and the first and second patterns are partially transferred to the ARC layer using a transfer process, such as an etching process or a developing process. Once the mask layer is removed, the first pattern and second patterns are completely transferred to the ARC layer using an etching process, and the first and second patterns in the ARC layer are transferred to the underlying thin film using another etching process.

    摘要: A method for patterning a substrate is described. The method includes forming a layer of radiation-sensitive material on a substrate, and preparing a pattern in the layer of radiation-sensitive material using a lithographic process, wherein the pattern is characterized by a critical dimension (CD) and a roughness. Following the preparation of the pattern in the layer of radiation-sensitive material, the method further includes performing a CD slimming process to reduce the CD to a reduced CD, and performing a vapor smoothing process to reduce the roughness to a reduced roughness.

    摘要: A method for image pattern recognition in a multi-image patterning scheme is described. The method includes forming a first feature pattern on a substrate using a lithographic process, and forming a second feature pattern on the substrate using the lithographic process. The method further includes forming an inspection alignment mark on the substrate to distinguish the first feature pattern from the second feature pattern. The inspection alignment mark comprises a negative tone pattern having a first alignment structure aligned with at least a portion of the first feature pattern and a second alignment structure aligned with at least a portion of the second feature pattern, wherein the first alignment structure is independent from the second alignment structure.
