WEBIn the first reaction a dry process is utilized involving oxygen gas as the oxygen source and the second reaction describes a wet process which uses steam. The dry process provides a "good" silicon dioxide but is slow and mostly used at the beginning of processing.
Thermal oxidation - Wikipedia
WEBThermal oxidation of silicon is usually performed at a temperature between 800 and 1200 °C, resulting in so called High Temperature Oxide layer (HTO). It may use either water vapor (usually UHP steam ) or molecular oxygen as the oxidant; it is consequently called either wet or dry oxidation.

WEBDry oxidation. The oxidation takes place under pure oxygen atmosphere. The silicon and oxide react to form silicon dioxide: Si + O 2 → SiO 2. This process is done at 1000 to 1200 °C actually. To create a very thin and stable oxide the process can be done at even lower temperatures of about 800 °C. Characteristic of the dry oxidation:
Thermal Oxidation - an overview | ScienceDirect Topics
WEBSilicon can be oxidized with either dry oxygen, or water. The oxidation rate is much more rapid with water as the reactant; hence it is preferred for films more than about 0.2 μm thick. Dry oxygen results in slightly denser films with better interface properties.
WEBHow Does Silicon Oxidize ? •Dry Oxidization : Si (solid) + O 2 (gas) ÆSiO 2 (solid) •Wet Oxidization: Si (solid) + 2H 2O (gas) ÆSiO 2 (solid) + 2H 2 (gas) •Silicon is consumed in the process •Oxidization occurs at the Si-SiO 2 interface, NOT on top of the oxide •The interface produced by thermal oxidization is not exposed to

WEBAug 3, 2023 · 3.1.1 Dry Oxidation. The dry oxidation of silicon takes place in a pure oxygen atmosphere according to the chemical reaction. $$\text {Si} \, + \text {O}_ {2} \to \text {SiO}_ {2}$$. This reaction typically occurs at a process temperature of 1000–1200 °C to achieve a sufficiently high growth rate.
WEBDesign of an oxidation furnace for the optional dry or wet oxidation of silicon deposited by cathode sputtering or thermal evaporation; however, these processes are not widely used in semiconductor technology due to their low oxide quality.
