An insert carrier is configured to receive at least one semiconductor wafer for double-side processing of the wafer between two working disks of a lapping, grinding or polishing process. The insert carrier includes a core of a first material that has a first surface and a second surface, and at least one opening configured to receive a semiconductor wafer. A coating at least partially covers the first and second surfaces of the core. The coating includes a surface remote from the core that includes a structuring including elevations and depressions. A correlation length of the elevations and depressions is in a range of 0.5 mm to 25 mm and an aspect ratio of the structuring is in a range of 0.0004 to 0.4.
