Silicon is the second most common element on the surface of the earth, trailing only oxygen. It is a blue-gray, brittle, chemical element in the same group as carbon. The process in which raw silicon is turned into a wafer can be extensive and lengthy. Let’s take a look at the process used to make a silicon wafer and how you can buy a silicon wafer.
The growing of a silicon ingot can take as long as one month to complete. The amount of time it takes can vary based on a number of factors, including size, quality, and the specification. More than three quarters are all single crystal silicon wafers are grown using the CZ method. The most common dopants used in the silicon wafer manufacturing process are boron, phosphorus, arsenic, and antimony.After the materials are combined, they are then heated to extremely high temperatures. Typically, they are heated to 1420 degrees Celsius, which is a temperature that is above the melting point of the silicon. Once everything has been liquefied, a silicon seed is positioned on top of the melt, barely touching the surface. That seed is used in the growing process of the wafer.Once the ingot is fully grown, it is made into a size that is just slightly larger than the final desired size and shape. After passing through inspections, it is sliced into wafers.
