    摘要: Improved complementary phase shift mask (c:PSM) imaging techniques are described, including a method in which scattering bars are provided on the trim mask in order to allow better CD uniformity to be achieved in the double exposure process. The number, size and position of the scattering bars can be optimised to achieve a desired isofocal CD and/or a desired level of sensitivity of the CD to trim exposure energy used in the second exposure step of the c:PSM process. The trim exposure dose can be regulated, and/or the trim width used on the trim mask can be optimised, to compensate for iso-dense bias so as to achieve optical proximity correction.

    摘要: A lithographic apparatus includes an illuminator configured to condition a beam of radiation and a support configured to hold a patterning device. The patterning device is configured to pattern the beam of radiation according to a desired pattern. The lithographic apparatus also includes a substrate table configured to hold a substrate and a projection system configured to project the patterned beam onto a target portion of the substrate to form a patterned image on the substrate. The apparatus further includes a sensor configured and arranged to intercept a portion of the beam and to measure a transmission of the beam through at least a portion of the patterning device.

    摘要: An EUV mask includes, on top of a multi-layer mirror, a spectral purity enhancement layer, for application in an EUV lithographic apparatus. On top of the spectral purity enhancement layer, a patterned absorber layer is provided. The spectral purity enhancement layer includes a first spectral purity enhancement layer, but between the multi-layer mirror and first spectral purity enhancement layer there may be an intermediate layer or a second spectral purity enhancement layer and intermediate layer. The patterned absorber layer may also itself function as an anti-reflection (AR) coating. The AR effect of this absorber layer is a function of the aperture sizes in the pattern. The spectral purity of a mask may be enhanced, such that DUV radiation is diminished relatively stronger than EUV radiation.
