Best Practices for Dow FOx-25 Flowable Oxide
-
Application
FOx Flowable Oxide is applied using standard spin-on glass equipment. It can be spin-coated under a wide range of conditions, which will optimize uniformity on complex geometries. After spin-coating, hot plates are used not only to remove solvent as with conventional SOGs, but also to melt and flow the film. The melt and flow properties of the material help to provide superior smoothing and gap fill.
-
Curing
After flow, the film is cured in a standard quartz diffusion furnace. At this point, the material is ready for the next processing step. No etchback is required.
