Patent ID: 8367279

Claim:
A reflective mask blank, comprising: a substrate, a multilayer reflective film formed on the substrate and having a structure in which a high refractive index layer and a low refractive index layer are alternately laminated, and an absorbing film stacked on the multilayer reflective film and adapted to absorb EUV exposure light, wherein the absorbing film comprises a phase shift layer adapted to give a predetermined phase difference to the EUV exposure light having passed therethrough and reflected by the multilayer reflective film with respect to the EUV exposure light directly incident on and reflected by the multilayer reflective film, and an absorber layer stacked on the phase shift layer and adapted to absorb and attenuate the EUV exposure light passing therethrough, either alone or jointly with the phase shift layer, wherein the phase shift layer and the absorbing layer are formed at least throughout an entire surface of a transfer pattern area and a blind area on the multilayer reflective film, and wherein the transfer pattern area comprises a transfer pattern while the blind area is provided to surround the transfer pattern area and to comprise no transfer pattern, when manufacturing a reflective mask from the reflective mask blank.
