    摘要: A method for performing leakage analysis includes receiving information specifying an integrated circuit. A neighborhood of shapes associated with the integrated circuit is then determined. Leakage information associated with the integrated circuit is generated based on the neighborhood of shapes. The neighborhood of shapes may be determined by determining a first set of spacings to a boundary of a first cell from an internal shape. A second set of spacings may be determined from the boundary of the first cell to a shape of a second cell. A lithography process may be characterized using the first and second set of spacings.

    摘要: A method uses a lithographic apparatus to form an inspection target structure upon a substrate. The method comprises forming the periphery of the inspection target structure so as to provide a progressive optical contrast transition between the inspection target structure and its surrounding environment. This may be achieved by providing a progressive change in the optical index at the periphery of the target structure.

    摘要: Some embodiments relate to a method of designing an integrated circuit layout. In this method, a plurality of design shapes are provided on different design layers over an active area within a graphical representation of the layout. A connection extends perpendicularly between a first design shape formed on a first design layer and a second design shape formed on the first design layer. First and second cut mask shapes on first and second cut mask design layers, respectively, are generated. The first cut shape removes portions of the first design layer and the second cut shape removes portions of the second design layer.

    摘要: The disclosed embodiments provide systems and methods for mitigating lensing and scattering as an optical fiber is being inscribed with a grating. The disclosed systems and methods mitigate the lensing phenomenon by surrounding an optical fiber with an index-matching material that is held in a vessel with a sealed phase mask. The sealed phase mask allows it to be in contact with a liquid index-matching material without having the liquid index-matching material seep into the grooves of the sealed phase mask. Thus, for some embodiments, the sealed phase mask may be immersed in a liquid index-matching material without adversely affecting the function of the phase mask.

    摘要: Provided is a phase shift amount measuring apparatus and method capable of measuring a phase shift amount and a transmittance of a phase shift mask in one measurement step by using a miniaturized monitor pattern. The phase shift amount and transmittance of the monitor pattern are simultaneously measured using a shearing interferometer. The phase shift amount is obtained from a phase difference of interference light between light passing through the monitor pattern and light passing through a non-pattern area. The transmittance of the monitor pattern is obtained using an amplitude of interference light between light passing through the monitor pattern and light passing through the non-pattern area and an amplitude of interference light between light beams passing through the non-pattern area. The use of common interference images in measuring the phase shift amount and transmittance enables measurement of both the phase shift amount and the transmittance in one measurement operation.
