Abstract

A method for forming a semiconductor device may include forming a silicon oxynitride mask layer over a first layer. The first layer may be etched using the silicon oxynitride mask layer, to form a pattern in the first layer. The pattern may be filled with a dielectric material. The dielectric material may be planarized using a ceria-based slurry and using the silicon oxynitride mask layer as a stop layer.
