While it might not be visible, silicon wafers are used in our everyday lives. A silicon wafer is a round piece of silicon which consists of silicon dies that are designed to perform a very specific functionally. Here are some fun facts that you need to know about silicon wafers.
Wafers are formed with a highly pure, almost defect-free single crystal material in a process called Czochralski. During the process, silicon or germanium is made by pulling a seed crystal from a melt.
Even though silicon is considered the most prevalent material, other compounds can be used as well. II-V or II-VI materials have also been used. Gallium arsenide is a III-V semiconductor that is produced during the Czochralski process. It’s often used as a common wafer material.
Proper storage conditions are important in order to prevent contamination and/or degradation. Wafers that are not vacuum sealed must be placed in a Nitrogen cabinet with a flow rate of 2 to 6 Standard Cubic Feet per Hour.
