1. An apparatus for processing a substrate, comprising:

  • a material conveyor assembly comprising;

    a platen having a substrate supporting surface;

    a first material positioning mechanism that is adapted to provide a supporting material to the substrate supporting surface;

    the supporting material having a first surface on which a plurality of features are formed; and

    a second material positioning mechanism that is adapted to receive the supporting material transferred across at least a portion of the substrate supporting surface from the first material positioning mechanism;

    one or more sensor assemblies disposed over the first surface, wherein the one or more sensor assemblies are positioned to sense the change in position of the plurality of features formed on the first surface; and

    a controller adapted to receive a signal from the one or more sensor assemblies and control the position of the supporting material on the substrate supporting surface using an actuator coupled to the first material positioning mechanism or the second material positioning mechanism.
