BOTTOM PROCESSING

Embodiments disclosed herein generally relate to methods and apparatus for processing of the bottom surface of a substrate to counteract thermal stresses thereon. Correcting strains are applied to the bottom surface of the substrate which compensate for undesirable strains and distortions on the top surface of the substrate. Specifically designed films may be formed on the back side of the substrate by any combination of deposition, implant, thermal treatment, and etching to create strains that compensate for unwanted distortions of the substrate. In some embodiments, localized strains may be introduced by locally altering the hydrogen content of a silicon nitride film or a carbon film, among other techniques. Structures may be formed by printing, lithography, or self-assembly techniques. Treatment of the layers of film is determined by the stress map desired and includes annealing, implanting, melting, or other thermal treatments.
