    Abstract: Methods of selectively depositing a feature onto a substrate surface while maintaining substantially straight sidewalls on the feature. A portion of the feature is grown and then covered with a protective film. The protective film is removed from the top of the feature, leaving some of the film on the sides of the feature and the process is repeated to grow a feature of desired thickness.
