Oxidation Furnace
An oxidation furnace is a specialized processing tool used in VLSI (Very Large Scale Integration) design and manufacturing. It involves a controlled oxidation process to modify the properties of semiconductor materials, such as silicon.
The oxidation furnace consists of a chamber with a high-temperature environment. The material to be oxidized is placed inside the chamber, and an oxidizing gas, such as oxygen or nitrogen, is introduced. As the gas flows through the chamber, it oxidizes the material, changing its chemical composition and properties.
The oxidation process can be used to achieve various objectives, including:
Doping: Introducing specific impurities into the material, such as phosphorus or arsenic.
Annealing: Repairing damage or defects in the material.
Oxidation of silicon nitride (SiN): Converting SiN to a more stable and conductive material, Si.
Release of trapped charges: Removing impurities or defects that may have been introduced during fabrication.
Oxidation furnaces are essential for the fabrication of advanced VLSI chips, which are used in a wide range of electronic devices, such as smartphones, computers, and medical equipment. By controlling the oxidation process, engineers can create chips with specific electrical, optical, and mechanical properties
