Abstract
A multilayer reflective film coated substrate includes a multilayer under film comprised of Mo/Si alternately-layered films and a multilayer reflective film comprised of Mo/Si alternately-layered films for reflecting exposure light. The multilayer under film and the multilayer reflective film are formed on a substrate in this order. Given that a cycle length of the multilayer under film is d bottom (unit:nm) and a cycle length of the multilayer reflective film is d top (unit:nm), a relationship of a formula (1) is satisfied when d bottom>d top, the formula (1) given by(+0.15)×top≦bottom≦(+0.9)×topwhere n is a natural number equal to or greater than 1.
