Abstract
A method for designing a grating comprises steps of (a1) generating a first diffraction spectrum based on calculation values of a plurality of structural parameters, (a2) calculating a first difference value between the first diffraction spectrum and a first nominal spectrum, (a3) setting a default difference value with the first difference value and default structural parameter values with the structural parameter values, (b1) changing one of the structural parameter values to generate a second diffraction spectrum, (b2) calculating a second difference value between the second diffraction spectrum and a second nominal spectrum, and (c) comparing the default difference value and the second difference value, updating a default difference value with the smaller one, and updating the default structural parameter values with the structural parameter values corresponding to the smaller one.
