Abstract:
Embodiments of the present disclosure generally relate to methods and apparatus for backside stress engineering of substrates to combat film stresses and bowing issues. In one embodiment, a method of depositing a film layer on a backside of a substrate is provided. The method includes flipping a substrate at a factory interface so that the backside of the substrate is facing up, and transferring the flipped substrate from the factory interface to a physical vapor deposition chamber to deposit a film layer on the backside of the substrate. In another embodiment, an apparatus for depositing a backside film layer on a backside of a substrate, which includes a substrate supporting surface configured to support the substrate at or near the periphery of the substrate supporting surface without contacting an active region on a front side of the substrate.
