    Abstract: Embodiments of the disclosure relate to methods using an oligomer film to protect a substrate surface. The oligomer film is formed on the substrate surface with a first feature and a second feature each having a feature depth. The first feature has a first critical dimension (CD) and the second feature has a second CD. The semiconductor substrate surface is exposed to one or more monomers to form the oligomer film, and the oligomer film forms selectively on the bottom and fills a portion of the feature depth. The oligomer film fills the feature depth to substantially the same or the same height in each of the first feature and the second feature. Methods of forming semiconductor devices using the oligomer film are also disclosed.
