Patent ID: 7351518

Claim:
A method for manufacturing a lithography mask, the method comprising: patterning a first electrically conducting material layer disposed over a substrate, applying a composition over the patterned first electrically conducting material layer, the composition comprising the following components: a resin that can be crosslinked to form a base polymer by thermal treatment, which is not patternable by electrically charged particles; an organic compound, initially nonconductive, that can be crosslinked to form a second electrically conductive substance by reaction with a crosslinking agent; a crosslinking agent having an oxidative or reductive effect; and at least one solvent; crosslinking the composition thereby producing a electrically conductive resist layer; forming a photoresist layer that can be patterned by means of electrically charged particles, the photoresist layer being formed on the electrically conductive resist layer; and producing structures in the photoresist layer by means of electrically charged particles with electrical charge being dissipated via the resist layer, wherein no structures are formed in the electrically conductive resist layer while producing the structures in the photoresist layer.
