Wafer Backgrinding & Silicon Wafer Thinning
Syagrus Systems uses the 3M Wafer Support System to meet the demands of today's technology companies for extremely thin silicon wafers and die used in complex applications. We have over 15 years of silicon wafer thinning and wafer backgrinding experience, including bumped wafer backgrinding and have provided wafer backgrind services since 1997.
Precision Backgrind & Wafer Thinning Services
We use fully-automated Disco and Strasbaugh wafer backgrinding equipment to achieve the highest possible level of quality and can continuously achieve thin wafer target thicknesses to less than 0.050mm (0.002”). To achieve these ultra-thin thicknesses requires a grind wheel with an extremely fine diamond grit. This ultra fine grind wheel is our standard for all backgrind target thicknesses and is superior to industry-standard 2000 grit. *Other grind wheel options are available upon request.
All wafer backgrinding is performed in a class 10K cleanroom with critical thin wafer taping processes performed at a class 100 workstation.
Because timing is critical, we have streamlined our wafer thinning process so that you can enjoy same-day, 24 hour, or 48 hour cycle times.
We stock a wide variety of tapes for backgrind use, so you can be sure we'll have the correct tape for your application.
Full-Service Wafer Backgrinding
Syagrus Systems takes pride in partnering with today’s startup technology companies, and we've become the back-end manufacturing arm for many fabless IC manufacturers. Whether you have one wafer or 10,000 wafers that require thinning or backgrind services, we understand that your success is our success.
Our custom backgrinding and wafer thinning service is capable of handling a wide variety of customer requirements, such as thinning partial wafers or single die.
Wafer thinning is only one step in our process offerings; through our supplier partners, we also offer post grind stress relief processes such as SEZ etch and CMP.
