    Abstract: A method for forming an anti-reflective coating (ARC) includes positioning a substrate below a target and flowing a first gas to deposit a first portion of the graded ARC onto the substrate. The method includes gradually flowing a second gas to deposit a second portion of the graded ARC, and gradually flowing a third gas while simultaneously gradually decreasing the flow of the second gas to deposit a third portion of the graded ARC. The method also includes flowing the third gas after stopping the flow of the second gas to form a fourth portion of the graded ARC. In another embodiment a film stack having a substrate having a graded ARC disposed thereon is provided. The graded ARC includes a first portion, a second portion disposed on the first portion, a third portion disposed on the second portion, and a fourth portion disposed on the third portion.

    Abstract: Methods for depositing a layer on a substrate are provided herein. In some embodiments, a method of depositing a metal-containing layer on a substrate in a physical vapor deposition (PVD) chamber may include applying RF power at a VHF frequency to a target comprising a metal disposed in the PVD chamber above the substrate to form a plasma from a plasma-forming gas; optionally applying DC power to the target; sputtering metal atoms from the target using the plasma while maintaining a first pressure in the PVD chamber sufficient to ionize a predominant portion of the sputtered metal atoms; and controlling the potential on the substrate to be the same polarity as the ionized metal atoms to deposit a metal-containing layer on the substrate.

    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.
