    摘要: Provided is an exposure apparatus including a variable focusing device. The variable focusing device may include a transparent membrane that may be deformed in the presence of an electric field. The deformation of the transparent membrane may allow the focus length of a radiation beam to be modified. In an embodiment, the variable focusing device may be modulated such that a radiation beam having a first focus length is provided for a first position on an exposure target and a radiation beam having a second focus length is provided for a second position on the exposure target. A method and computer-readable medium are also provided.

    摘要: Provided is a non-transitory computer readable medium including instructions to generate a level sensor map and create a compensation map from the level sensor map. The level sensor map includes a first determination of a first height above a reference plane of a feature disposed on a semiconductor substrate, and a second determination of a second height above the reference plane of a second feature disposed on a semiconductor substrate. The first and second feature are in a single exposure field. The compensation map includes a determination of at least one parameter to be used during exposure of a single field during an exposure process for the semiconductor substrate.

    摘要: The overlay mark and method for making the same are described. In one embodiment, a semiconductor overlay structure includes gate stack structures formed on the semiconductor substrate and configured as an overlay mark, and a doped semiconductor substrate disposed on both sides of the gate stack structure that includes at least as much dopant as the semiconductor substrate adjacent to the gate stack structure in a device region. The doped semiconductor substrate is formed by at least three ion implantation steps.

    摘要: Provided is a lithography system that includes a source for providing energy, an imaging system configured to direct the energy onto a substrate to form an image thereon, and a diffractive optical element (DOE) incorporated with the imaging system, the DOE having a first dipole located in a first direction and a second dipole located in the first direction or a second direction perpendicular the first direction. The first dipole includes a first energy-transmitting region spaced a first distance from a center of the DOE. The second dipole includes a second energy-transmitting region spaced a second distance from the center of the DOE. The first distance is greater than the second distance.
