Methods of Modifying Oxide Spacers |
摘要 |
Methods for reducing line roughness of spacers and other features utilizing a non-plasma and non-wet etch fluoride processing technology are provided. Embodiments of the methods can be used for spacer or line reduction and/or smoothing the surfaces along the edges of such features through the reaction and subsequent removal of material. |
