Claim 2:
3. The EUV mask blank substrate processing platform of claim 2, further comprising a controller configured to execute instructions to cause the EUV mask blank substrate processing platform to load a substrate from the factory interface, to a first load lock chamber and to a first multi-cathode PVD chamber, deposit a layer on a front side of the EUV mask blank substrate, remove the EUV mask blank substrate from the first multi-cathode PVD chamber and load the EUV mask blank substrate in one of the first load lock chamber and the second load lock chamber and then transfer the EUV mask blank substrate back to the factory interface, rotate the EUV mask blank substrate 180 degrees to provide a rotated substrate, transfer the rotated substrate to one of the first load lock chamber and the second load lock chamber, load the rotated substrate to a second multi-cathode PVD chamber and deposit a layer on the back side of the rotated substrate.
