Silicon Wafers & Semiconductor Wafers

Quality silicon wafers and semiconductor wafers are essential substrates for electronic circuits and today's electronic and medical devices. These thin slices of crystalized silicon possess critical conductivity and semiconductor properties, making them vital to the technology sector. When you need various shapes and sizes of silicon wafers, MSE Supplies has solutions to meet every customer's specific requirements.

Silicon Wafer Applications

Silicon wafers are critical components of Integrated Circuits, used widely throughout many industries. Various doped and undoped wafers in different sizes and shapes are essential to electronics and computing, semiconductors, optics, RF communication, aerospace, solar cells, and photonics. 

How Do You Choose A Silicon Wafer?

When evaluating silicon wafers, there are several vital factors to consider:

  • Diameter - Getting the right size wafer is key, and our silicon wafers range from 10 to 300 millimeters in diameter.
  • Thickness - Silicon wafers must be thick enough to maintain structural integrity throughout manufacturing and product use.
  • Type & Dopant - Depending on your application, you may need undoped silicon wafers or wafers doped with a specific dopant such as Boron or Phosphorus.
  • Surface Finish - The right surface finish, either polished to a mirror finish or etched, impacts electron mobility and device degradation.
  • Resistivity - Silicon wafers with the appropriate resistivity for your application are critical to the device’s performance.

If your application requires custom silicon wafers, we manufacture the wafers to your specifications. Both NASA and Harvard University rely on our custom semiconductor wafers. Click here to Request a quote for your customized project.
