    Abstract: An attenuated phase shift patterning device including a first component for reflecting radiation, and a second component for reflecting radiation with a different phase with respect to the radiation reflected from the first component, the second component covering at least a portion of the surface of the first component such that a pattern including at least one uncovered portion of the first component is formed for generating a patterned radiation beam in a lithographic apparatus in use, wherein the second component includes a material having a refractive index with a real part (n) being less than 0.95 and an imaginary part (k) being less than 0.04.

    Abstract: A method of tuning a patterning stack, the method including: defining a function that measures how a parameter representing a physical characteristic pertaining to a pattern transferred into a patterning stack on a substrate is affected by change in a patterning stack variable, the patterning stack variable representing a physical characteristic of a material layer of the patterning stack; varying, by a hardware computer system, the patterning stack variable and evaluating, by the hardware computer system, the function with respect to the varied patterning stack variable, until a termination condition is satisfied; and outputting a value of the patterning stack variable when the termination condition is satisfied.
