WebChemical vapor deposition (CVD) oxide is a linear growth process where a precursor gas deposits a thin film onto a wafer in a reactor. The growth process is low temperature and has a much higher growth rate when compared to thermal oxide. It also produces much thinner silicon dioxide layers because the film is deposted, rather than grown.
