  • Wet oxidation - Wikipedia

    Wet oxidation is a form of hydrothermal treatment. It is the oxidation of dissolved or suspended components in water using oxygen as the oxidizer.It is referred to as "Wet Air Oxidation" (WAO) when air is used. The oxidation reactions occur in superheated water at a temperature above the normal boiling point of water (100 °C), but below the critical point (374 °C).

  • Comparison Of Wet And Dry Oxidation Of Silicon Dioxide

    AbstractIntroductionTheoryWet OxidationDry OxidationResults and DiscussionConclusionSilicon dioxide plays a major role in the present technology. The basic idea is to grow SiO2 layer on Silicon. The oxide is grown on intrinsic silicon substrate by thermal oxidation i.e., wet oxidation and dry oxidation. The thickness is compared for both the oxidation processes. The time of an oxidation cycle is maintained constant and temperature is varied. The oxide thickness is monitored for different number of cycles. The capacitance per unit length is also calculated for t

    The long time required to grow a thick oxide in dry oxidation makes this process impractical. Thick oxides are usually grown with a long wet oxidation bracketed by short dry ones (a dry-wet-dry cycle). The beginning and ending dry oxidations produce films of high-quality oxide at the outer and inner surfaces of the oxide layer, respectively. Mobile metal ions can degrade

  • Oxidation Process in IC Fabrication

    As wet oxidation occurs at a substantially greater rate than dry oxygen, any unintentional moisture accelerates the dry oxidation.

During thermal oxidation process, an interface is formed, which separates

    However, the oxidation process does not stop at the edge of the mask, because the oxidants are able to diffuse through the already existing oxide into regions under the mask and react there with silicon (see Fig. 2.4). The finally oxide regions are therefore normally larger than the not masked ones, but there are also natural mechanisms which strongly restrict or nearly stop the oxidation
