Abstract: A treatment tool for reconditioning the top surfaces of a plurality of projections of a substrate support in a lithographic tool. The treatment tool includes a reconditioning surface which is rough relative to smoothed top surfaces of the projections and which reconditioning surface has material harder than that of the material of the top surfaces of the projections. A reconditioning method involves causing an interaction between the reconditioning surface of the treatment tool and the top surfaces of the projections of the substrate support, so as to leave these top surfaces rougher than they were prior to the interaction.
