Video: Dry Thermal Oxidation Process Explained
The Rate of Oxidation is an important parameter when studying the oxidation process. The rate of oxide growth is proportional to the effective diffusion coefficient of water molecules into the oxide layer and its equilibrium concentration within the area of reaction. A carrier gas reduces this partial pressure of water vapor and slows the diffusion of water molecules into the oxide film. This slowing effect results in a decrease in the driving force and therefore in the rate of oxide growth. For this reason, it is possible to set a fixed rate of growth.
This process of growing dry thermal oxide has a few distinct advantages. First of all, it is possible to grow thin oxides on silicon substrates. The process of thermal oxidation is a highly controlled process and can be completed on a wide variety of materials. In order to grow thin layers, furnace tubes can be used. For example, furnace tubes are available for growing dry thermal oxide. Moreover, they are CMOS-compatible, so they can be used for various applications.
This process is also referred to as the Dry Thermal Oxidation of Silicon. It is a reaction-limited process that involves a series of thermal treatments and is therefore ideally suited for silicon oxide manufacturing. However, the thickness of the film limits the rate of growth, which slows down the production of silicon oxide. Therefore, a thick film of silicon oxide will slow down the rate of oxidation. This is the reason why thick layers of silicon oxides are usually avoided in silicon manufacturing.
Thermal oxidation is an important process for the manufacture of thin layers of silicon dioxide. This chemical reaction allows oxygen molecules to react with the surface of a silicon wafer, resulting in a thin layer of silicon dioxide. Silicon dioxide is an excellent dielectric material and is often used in MEMS devices. There are many applications for thermal oxidation. There are two main types: the silicon dioxide layer and the thermal oxidation of silicon.
Wet oxidation is a method in which oxygen and water are oxidized to form metallic oxides. The oxidation rate depends on the effective diffusion coefficient of water molecules into the oxide film, and the equilibrium concentration of the two gases in the area. Carrier gas molecules lower the water vapor partial pressure, which slows the diffusion of water into the oxide film. The lower driving force, compared to water alone, reduces the rate of growth.
Wet oxidation is used for thicker silicon dioxide layers than dry thermal oxide, and is often used to produce the final thick-film silicon-on-insulator (ThFSIS) films that are essential in electronics. Wet thermal oxide is also used as a barrier on thick-film silicon on insulator wafers and in chemical mechanical planarization. For electrical insulators, this method is preferable.
The oxidation of silicon is one of the most common steps in the manufacture of integrated circuits (ICs). The ability to create an even and uniform oxide film is essential to the success of IC manufacturers. Historically, water vapor was used to grow oxides, but new steamer designs have replaced direct water injection and water bubblers. Steamers have many advantages, including less expensive production, reduced film contamination, and improved growth rate.
In addition to comparing the growth rate between the two oxidation methods, HO/O has the highest oxidation rate. Using the same percentage of HCL or Cl leads to the same amount of oxidation. Wet oxidation is often a faster process than dry oxidation. So which method is right for you? The answer depends on your application. Wet oxidation is a better choice for those with high-quality silicon-based electronics.
In both cases, water vapor pressure increases the oxidation rate. Researchers have reported that water pressure increased the rate of growth by as much as four times, while dry oxidation produced no change. In Figure 3, the growth rate increased with increasing pressure and temperature. The greater the pressure and temperature, the thicker the oxide layer.
