Metal Film Capacitor Ozone

Ozone as the Oxidizing Precursor in Atomic Layer Deposition

Ozone has distinct advantages over the alternative oxidizing precursors in the ALD of advanced dielectric films. The high electrochemical potential of ozone (Table 1) results in fast reaction rates at relatively low temperatures. Ozone is highly volatile, shortening purge times between cycles.

Metallized film capacitors used for EMI filtering: A reliability review

Film capacitors are generally subdivided into film/foil capacitors and metallized film capacitors. Film/foil capacitors consist of alternating layers of polymer or paper film and metal foil that are wound together.
