CVD (Chemical Vapor Deposition) is used to deposit materials in various forms, including monocrystalline, polycrystalline, amorphous, and epitaxial. By subtypes, there are mainly LPCVD (low pressure), PECVD (plasma enhanced), and ALD. PVD deposition techniques include sputtering and eBeam and thermal evaporation. The CVD process involves mixing the source material with one or more volatile precursors using a plasma to chemically interact and breakdown the source material. The processes use heat with higher pressures leading to a more reproducible film where the film thicknesses could be managed by time/power. These films are more stoichiometric, they are denser and are capable of growing higher quality insulator films. The PVD processing uses a solid precursor metal that is gasified through some electrical energy. The gasified atoms are then transferred to the substrate. These processes manages thicknesses using a quartz crystal rate monitor to control rate and thickness of the film.
