    • A displacement measuring system, a lithography device, and a manufacturing method thereof are provided to reduce sensitivity against an error and to decrease an installation space thereof. A displacement measuring system comprises first and second diffraction lattices, a sensor(216), and at least one linear polarizer(217,218). The first diffraction lattice is used to divide a first beam of inputted radiation into first positive and negative diffraction radiation beams(212,213). The first positive and negative diffraction radiation beams are diffracted more by the second diffraction lattice. The sensor is used to decide a relative displacement between the first and second diffraction lattices from a decision of a phase difference between a first component of the second beam deduced from the first positive diffraction radiation beam, and a second component of the second beam deduced from the first negative diffraction radiation beam. The linear polarizer is formed to diffract the first and second components of the second beam linearly and to position and cross the first and second components mutually. A lithography device is used to detect the displacement of the first component thereof against the second component thereof.
    • 提供了位移测量系统,光刻设备及其制造方法,以降低对错误的灵敏度并减小其安装空间。 位移测量系统包括第一和第二衍射栅格,传感器(216)和至少一个线性偏振器(217,218)。 第一衍射栅格用于将第一射入的辐射束分成第一正和负衍射辐射束(212,213)。 第一正和负衍射辐射束被第二衍射晶格衍射更多。 该传感器用于根据从第一正衍射辐射束推断的第二光束的第一分量与从第一正衍射辐射束推导出的第二光束的第二分量之间的相位差的判定来确定第一和第二衍射光栅之间的相对位移 第一个负衍射辐射束。 线性偏振器被形成为线性地衍射第二光束的第一和第二分量并相互定位和交叉第一和第二分量。 光刻装置用于检测其第一部件相对于其第二部件的位移。

    • A method and a system for enhanced lithographic patterning are provided to print a pattern having a feature interval less than a printable minimum interval within a hard mask by using a single exposure method. A patterned radiation beam is applied to a hard mask layer provided on a substrate. First parts of the hard mask layer are exposed by using a first dose of radiation necessary for enhancing etch characteristics of the first parts from the patterned radiation beam. Second parts different from the first parts of the hard mask layer are exposed by using a second dose of radiation necessary for enhancing etch characteristics of the second parts from the patterned radiation beam. An etch process for the hard mask layer is performed. The first parts and the second parts are removed. Parts of the hard mask layer except the first and second parts are not damaged.
