During the phase-0 upgrade, the Insertable B-Layer (IBL) was installed closest to the beam pipe. Its pixels are arranged with a pitch of $250\\,\\mu$m$\\,\\times\\,50\\,\\mu$m with a rectangular shaped n$^+$ implantation. Based on this design modified pixel designs have been developed in Dortmund.\n  Six of these new pixel designs are arranged in structures of ten columns and were placed beside structures with the standard design on one sensor.
