    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 forming a metal dielectric etching stop layer onto a substrate with good etching selectivity and low wet etching rate. In one embodiment, a method of sputter depositing a metal dielectric etching stop layer on the substrate includes transferring a substrate in a processing chamber, supplying a gas mixture including at least N2 gas into the processing chamber, applying a RF power to form a plasma from the gas mixture to sputter source material from a target disposed in the processing chamber, maintaining a substrate temperature less than about 320 degrees Celsius, and depositing a metal dielectric etching stop layer onto the substrate from the sputtered source material.

    Abstract: The embodiments herein provides methods for forming a PVD silicon oxide or silicon rich oxide, or PVD SiN or silicon rich SiN, or SiC or silicon rich SiC, or combination of the preceding including a variation which includes controlled doping of hydrogen into the compounds heretofore referred to as SiOxNyCz:Hw, where w, x, y, and z can vary in concentration from 0% to 100%, is produced as a hardmask with optical properties that are substantially matched to the photo-resists at the exposure wavelength. Thus making the hardmask optically planarized with respect to the photo-resist. This allows for multiple sequences of litho and etches in the hardmask while the photo-resist maintains essentially no optical topography or reflectivity variations.
