Abstract
Embodiments disclosed herein include a method of developing a metal oxo photoresist with a non-wet process. In an embodiment, the method comprises providing a substrate with the metal oxo photoresist into a chamber. In an embodiment, the metal oxo photoresist comprises exposed regions and unexposed regions, and the unexposed regions comprise a higher carbon concentration than the exposed regions. In an embodiment, the method further comprises flowing a gas into the chamber, wherein the gas reacts with the unexposed regions to produce a volatile byproduct.
