Cathode sputtering apparatus with a high sputtering rate, including a cathode having a cathode base 1 and a target 6 disposed parallel thereto and being provided with a channel 5 in the cathode base which is passed through by a cooling agent 12. With respect to the target 6, 10 to be cooled, this channel 5 is bounded by a thin wall 2 configured as a membrane. The wall 2 has large contact surfaces exhibiting a good heat transfer to the target surface. The contact surface between the target 6 and the wall 2 is coated with a material, e.g. a graphite layer, which has a low sputtering rate in order to delay a sputtering through as long as possible.
