Did you know that the Swedish scientist Jöns Jacob Berzelius first discovered silicon all the way back in 1824?
Since then, the element has been an important factor in modern technology. This is especially true of silicon wafer designs. Despite the benefits of this tech, it's not invulnerable.
This is why you should do your best to keep your silicon wafers in great condition. Are you wondering how? Keep reading to learn about the main causes of silicon wafer breakage and how you can prevent them.
What Are Silicon Wafers?
It's important to note that silicon wafers are made from a pure and crystalline form of silicon. This element comes from quartzite or sand.
After extraction, it's processed and purified so that the wafer has the highest quality possible. As you can imagine, the manufacturing process behind silicon wafers is complex. It involves several different stages, such as slicing, polishing, doping, and more.
One of the main causes of breakage is stress from the silicon wafer manufacturing process. Slicing the silicon ingot into wafers involves a high level of precision. Any inaccuracies can cause stress and even microcracks.
Aside from this, polishing the wafer's surface can also lead to the creation of small cracks. This will weaken the wafer's structure and make it more susceptible to breakage.
Another cause of silicon wafer breakage is mishandling during transportation and storage. Silicon wafers are quite fragile and can be easily damaged if mishandled.
Any sudden jolt or high vibration can cause the wafer to break or crack. Keep in mind that exposure to extreme temps or high humidity can cause the wafer to expand or contract. This is also a major cause of wafer breakage.
How Can I Prevent Breakage?
Do you want silicon wafers for sale? Preventing silicon wafer breakage is crucial for silicon wafer manufacturers to ensure high-quality products and avoid financial losses.
Silicon wafer manufacturers should invest in high-quality equipment that's designed to reduce stress during the manufacturing process. Using the best precision slicing and polishing equipment can help reduce breakage risks.
Emphasize to your team that silicon wafers should be handled with extreme care and stored in a controlled environment. The temperature and humidity of the storage area should be monitored to prevent any wafer expansions or contractions.
Silicon carbide wafers should be inspected for any defects or microcracks before and after each stage of the manufacturing process.
