    • The relative surface area sizes of portions having distinct phase-shift and transmission of light of a pattern on a phase-shift mask substantially obey the condition that the product of surface area and transmission of the electrical field strength is the same for all of the portions. Then, frequency doubling occurs due to vanishing zero order diffraction orders and in the case of high-transition attenuated phase-shift masks a large first order diffraction amplitude reveals an even an improved as compared with conventional phase-shift masks. Two-dimensional matrix-like structures particularly on attenuated or halftone phase-shift masks can be arranged to image high-density patterns on a semiconductor wafer. The duty cycles of pattern matrices can be chosen being different from one in two orthogonal directions nevertheless leading to frequency doubling.
    • 在相移掩模上具有明显的相移和图案的光的透射的部分的相对表面积大小基本上遵循对于所有部分的表面积和电场强度透射率的乘积相同的条件 。 然后,由于零阶衍射级消失而发生倍频,并且在高转变衰减相移掩模的情况下,与常规相移掩模相比,大的一级衍射幅度显示出均匀的改善。 特别是在衰减或半色调相移掩模上的二维矩阵状结构可以被布置成对半导体晶片上的高密度图案进行成像。 可以选择模式矩阵的占空比不同于两个正交方向上的一个,但是导致倍频。

    • A first and a second phase-shifting, semitransparent layer are formed on a substrate. The layers are patterned lithographically to form first elevated structure elements on the substrate with a first degree of transmission and second structure elements with a second degree of transmission, where the second degree of transmission is different from the first degree of transmission. Memory products can be produced with high resolution and high dimensional accuracy when the structure elements are transferred to a semiconductor substrate, by virtue of dense structure arrangements being represented by the structure elements with a high degree of transmission of more than 30% and, on the same mask, isolated structure arrangements having a low density being represented by the structure elements with a lower degree of transmission.
