The mask is designed in such a way that during the deposition of the gate electrodes on the corner of the substrate the metal should cover the edge of the substrate as well. This ensures conductivity between the metal electrodes and the p-doped silicon. If you find the edges of the substrate not to be conductive you must scratch the edges of the substrate to remove the insulating silicon oxide in correspondence with the corner where the gate electrode will be deposited.
