An electrical connector comprises a high voltage pad and a high voltage plate. When connected to another electrical connector, the two plates, which are at the same voltage as the pads, form a region of high voltage in which the field is low. The pads are positioned in that region. An electrostatic clamp of an EUV lithographic apparatus may have such a pad and plate, for connecting to the electrical connector. By placing the interconnection in a low field region, triple points (points of contact between a conductor, a solid insulator and a gas) may be present in that region. |
