CHEMICAL VAPOR CONDENSATION DEPOSITION OF PHOTORESIST FILMS

Abstract:

Embodiments disclosed herein include methods of depositing a metal oxo photoresist using chemical vapor condensation deposition processes. In an example, a method for forming a photoresist layer over a substrate in a vacuum chamber includes providing a metal precursor vapor into the vacuum chamber from an ampoule maintained at a first temperature. The method further includes providing an oxidant vapor into the vacuum chamber, where a reaction between the metal precursor vapor and the oxidant vapor results in the formation of the photoresist layer on a surface of the substrate. The photoresist layer is a metal oxo containing material. The substrate is maintained at a second temperature less than the first temperature during the formation of the photoresist layer on the surface of the substrate.
