Flowable CVD: Gap Filling, Material Conversion and Planarization
Flowable chemical vapor deposition (FCVD) allows a depositing silicon-containing network to redistribute into narrow gaps, reducing the risk that the entrance closes before the interior is filled. Filling establishes where the material goes. Conversion and densification establish its material condition. CMP removes excess material and establishes a plane. A filled outline alone cannot demonstrate all three outcomes.
