A silicon wafer supplier produces two grades of silicon substrates: standard silicon wafers and silicon chips, and ultra-flat silicon wafers. Each has its purpose and is used for different applications. In this article, we will discuss what you need to know about the two grades of silicon substrates.
A silicon wafer supplier produces standard silicon wafers and silicon chips to be used as biological substrates in thin-film research, sample substrates, and for micro-fabrication applications. They make good flat substrates for SEM imaging of particles because of their low background. They also have similar properties as glass, so they can be used to grow cells for biological applications. They can easily be divided or used as a whole wafer.
Ultra-flat silicon wafers and ultra-flat silicon chips have higher specifications compared to standard silicon wafers and chips. They're used for demanding applications that have specific requirements, specifically in micro-fabrication. But they can also be used for biological applications since they have similar properties as glass and can be used to mount cells.They're also used for high-resolution SEM imaging of particles due to its low background noise. For larger substrates, they can be easily divided into the client's desired size. They're packed in a cleanroom using a wafer carrier tray for protection. Ultra-flat silicon chips are accurately diced using a dicing saw, cleaned, and packed in a clean gel-box.
