CONTROLLING ETCH ANGLES BY SUBSTRATE ROTATION IN ANGLED ETCH TOOLS

Embodiments described herein relate to methods of forming gratings with different slant angles on a substrate and forming gratings with different slant angles on successive substrates using angled etch systems. The methods include positioning portions of substrates retained on a platen in a path of an ion beam. The substrates have a grating material disposed thereon. The ion beam is configured to contact the grating material at an ion beam angle custom-character relative to a surface normal of the substrates and form gratings in the grating material. The substrates are rotated about an axis of the platen resulting in rotation angles ϕ between the ion beam and a surface normal of the gratings. The gratings have slant angles custom-character relative to the surface normal of the substrates. The rotation angles ϕ selected by an equation ϕ=cos.sup.−1 (tan(custom-character)/tan(custom-character)).
