Claim 23:
24. A method for processing an object using a material processing device, comprising:
determining a region of interest of the object arranged on or in a first material region of the object using a determination device of the material processing device;
ablating material from a second material region of the object using an ablation device of the material processing device, the second material region adjoining the first material region, the first material region having a first portion and a second portion adjoining the first portion, and the region of interest being arranged in the first portion;
recognizing a geometric shape of the first material region, following the ablation and/or during the ablation of the material from the second material region, in a plan view of the first material region using a control device of the material processing device, the geometric shape having a center, the center being arranged at a first position, wherein if the region of interest or the projection of the region of interest on the surface of the first material region is not arranged at the center of the geometric shape, defining the region of interest or the projection of the region of interest on the surface of the first material region as the center of the geometric shape and defining the arrangement of the geometric shape with the now defined center around the defined center;
ablating material from the second portion of the first material region using a particle beam of a particle beam apparatus, the first portion having a first subregion and a second subregion, the region of interest being arranged in the first subregion;
recognizing a further geometric shape of the first material region, following the ablation of the material from the first portion, in a plan view of the first material region using the control device of the material processing device, the further geometric shape having a further center, the further center being arranged at a second position;
positioning the object using a moveable object holder and/or positioning the particle beam using the particle beam apparatus, in such a way that the first position of the center corresponds to the second position of the further center, wherein the region of interest is arranged at the further center of the further geometric shape or a projection of the region of interest on the surface of the first material region is arranged at the further center of the further geometric shape; and
ablating material from the second subregion of the first material region using the particle beam of the particle beam apparatus.
