Claim 7:
8. A method of producing a reconditioning wafer in accordance with claim 1, the method comprising:
providing a mold substrate;
by lithography and etching, producing one or more two dimensional arrays of regularly spaced molds in the mold substrate, the molds having substantially the same shape and dimensions, the molds having slanted sidewalls and an apex area;
depositing a layer of the indentation material on the mold substrate, thereby at least partially filling or lining the molds with the indentation material, so that the indentation material is deposited at least on the bottom of the molds;
bonding the mold substrate to the carrier substrate, by bonding the layer of indentation material or one or more further layers deposited on top of the layer of indentation material to the carrier substrate; and
removing the mold substrate to reveal the outer surfaces of the protrusions of the reconditioning wafer.
