Abstract: An inference method includes inferring a value that includes a stress value in a region located 50 μm or shallower from a surface of a chemically strengthened glass, by receiving as input at least a temperature and a time used upon chemical strengthening, and stress values at three or more different depth positions 20 μm or deeper from the surface of the chemically strengthened glass that has been obtained by chemically strengthening a glass having a thickness of 0.2 mm or greater with the temperature and the time.

Abstract: A reflective mask blank, which is a binary reflective mask blank, includes, in order: a substrate; a multilayer reflective film configured to reflect EUV light; and a pattern film. The pattern film has a laminated structure including a total of L layers each having a different refractive index where L is a natural number of 2 or more. When an absorption coefficient of an i-th layer in the pattern film from a side opposite to the substrate is defined as ki, a thickness of the i-th layer in the pattern film from the side opposite to the substrate is defined as di (nm), a total thickness of the pattern film is defined as d, an exposure wavelength is defined as λ (nm), and Pi is defined as 1−exp(−2π/λ*diki), the following formula (1) is satisfied. ∑ i = 1 L ( P i / d ) > 0.012 ( 1 )
