Thermal 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. The reaction is … See more In microfabrication, thermal oxidation is a way to produce a thin layer of oxide (usually silicon dioxide) on the surface of a wafer. The technique forces an oxidizing agent to diffuse into the wafer at high temperature and react with it. … See more Most thermal oxidation is performed in furnaces, at temperatures between 800 and 1200 °C. A single furnace accepts many wafers at the same time, in a specially designed quartz rack (called a "boat"). Historically, the boat entered the oxidation chamber … See more Thermal oxidation can be performed on selected areas of a wafer, and blocked on others. This process, first developed at Philips, is commonly referred to as the local oxidation of silicon (LOCOS) process. Areas which are not to be oxidized are covered … See more Wet oxidation is preferred to dry oxidation for growing thick oxides, because of the higher growth rate. However, fast oxidation leaves more dangling bonds at the silicon interface, which produce quantum states for electrons and allow current to leak along … See more • Online calculator including deal grove and massoud oxidation models, with pressure and doping effects at: See more WebMay 4, 2024 · Longer laser pulses lead to high temperatures and a mechanism known as thermal ablation, in which the ablation plume absorbs most of the laser energy.
