Claim 7:
8. The method according to claim 1, further comprising processes of, prior to process (a):
(i) providing reference deposition conditions and reference dry-etching conditions under which a layer structure having a reference topology profile is formed in the step on the substrate by conducting process (a) and process (b);
(ii) upon comparing the thus-obtained reference topology profile with the target topology profile, changing at least one parameter of the reference deposition conditions and/or at least one parameter of the reference dry-etching conditions in a manner forming a layer structure having a topology profile in the step on the substrate, which is more similar to the target topology profile than is the reference topology profile;
(iii) conducting process (a) and process (b) under the changed deposition/dry-etching conditions; and optionally
(iv) repeating processes (ii) and (iii) until the thus-obtained topology profile is substantially equivalent to the target topology profile.
