WebJul 15, 2024 · The HPS-CVD design can be classified as a vertical CVD reactor with a rotating susceptor. Critical to the design is the physical separation of precursors into separate chambers and a rotating susceptor carrying a substrate sequentially through each chamber in a circular motion. WebAug 25, 2010 · AMAT’s answer: a liquid flowable CVD, dubbed Eterna FCVD, that "fills anything" with up to 30:1 aspect ratios. It can fill (full and partial) 5nm geometries with "very little overburden," and also around and underneath things like 10nm overhangs, they claim. The other benefit of the new technology is elimination of carbon in film, which ...
