WebOxide growth appears to be faster on (111) oriented silicon when compared to (100) oriented silicon. In fact, in [ 122] it is shown that the (111) and (100) orientations represent the upper and lower bound for oxidation rates, respectively. All other silicon orientations lie between these extrema. WebWet Thermal Oxide, grown with the help of wafer vapor, yields Oxide layer thickness from from 0.12 to 2.4µm, or even up to 10µm 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 …
