Silicon Wafer Backgrinding & Wafer Thinning Services

Wafer backgrinding, or wafer thinning, is a semiconductor service designed to reduce wafer thickness. This complex manufacturing process produces ultra-thin wafers for stacking and high-density packaging in compact electronic devices.

Syagrus Systems is an experienced provider of wafer grinding services. Our engineers can achieve your desired thickness and surface smoothness without damaging or compromising the strength of your silicon wafers. We use the 3M™ Wafer Support System to meet demands for extremely thin silicon wafers and die used in complex applications. Whether you have one or several thousand silicon wafers that require thinning or back grinding, we have the right solution for your project. Our capabilities include:

  • Thin wafers from 4” to 8” diameter
  • Backgrinding to target thickness of 0.025mm (0.001”)
  • Single die, partial wafer, or bumped wafer backgrinding
  • Thickness variance under 5 microns

Syagrus Systems can take your thin wafer all the way to singulated die form through our comprehensive silicon wafer services. Contact us today to learn more about our abilities and wafer thinning processes. Request a quote to start your order.

Wafer Backgrinding & Wafer Thinning Processes Deliver Quality

Silicon wafer backgrinding uses a diamond-resin bonded grinding wheel to remove the silicon material from the back of a wafer. This process is effective, fast, and less expensive than chemical-mechanical alternatives, efficiently removing the bulk of substrate material before the final finish grind, polish, or chemical etch. Throughout the wafer grinding process, deionized water is used to wash debris from the surface and prevent contamination.

UV curable or standard adhesive backgrinding tape is temporarily applied to protect your silicon wafers from damage during wafer grinding. We stock a wide variety of backgrinding tapes for wafer thinning to ensure we’ll have the correct surface protection for your application.
