Apparatus for UV flowable dielectric

Abstract:

Provided are methods and apparatus for ultraviolet (UV) assisted capillary condensation to form dielectric materials. In some embodiments, a UV driven reaction facilitates photo-polymerization of a liquid phase flowable material. Applications include high quality gap fill in high aspect ratio structures and pore sealing of a porous solid dielectric film. According to various embodiments, single station and multi-station chambers configured for capillary condensation and UV exposure are provided.
