Abstract: A bottom lens for an immersion exposure tool includes a hydrophobic coating on the sidewalls of the bottom lens. A bottom portion of the bottom lens is not coated with the hydrophobic coating to maintain the optical performance of the bottom lens and to not distort a pattern that is to be transferred to a substrate.
