Claim 36:
37. The method of claim 36 wherein the beam-induced deposition of material uses at least one precursor material, the beam-induced etching uses at least one etching gas, and
wherein varying one or more parameters of the beam-induced etching comprises at least one of:
(i) increasing the intensity of the beam of charged particles;
(ii) changing an interaction duration of the beam of charged particles with the sample;
(iii) reducing an amount of the at least one precursor material provided to the part of the surface of the sample to reduce the concentration of the at least one precursor material at the part of the surface of the sample;
(iv) depleting the precursor material in the core region of the beam of charged particles;
(v) reducing an amount of the at least one etching gas provided to the part of the surface of the sample to reduce the concentration of the at least one etching gas at the part of the surface of the sample; or
(vi) depleting the etching gas in the core region of the beam of charged particles.
