growing wet thermal oxide vs dry thermal oxide growth

Wet Thermal Oxide, grown with the help of wafer vapor, yields Oxide layer thickness from from 0.12 to 2.4m, or even up to 10m on special order. DRY Thermal Oxide, grown in the absence of wafer vapor, yields a more dense Oxide layer but only layers from 10 to 300nm are practical. The Oxide layer is a thermally grown SiO2 layer, grown by actually oxidizing the Silicon atoms on the Silicon
