Semiconductor Silicon Wafer Services
Syagrus Systems is one of the industry’s leading providers of post-fab, backend processing for silicon wafers used in semiconductor and electronic component manufacturing. With extensive experience and state-of-the-art processing equipment, we deliver superior results. Our available services include:
This innovative system provides temporary support for wafers during thinning operations and post-thinning processes. A UV-curable adhesive along with a precision glass substrate supports the topography of wafer circuit patterns to minimize physical stresses during thinning operations.
Our wafer thinning and backgrinding processes can achieve wafer target thicknesses of less than 0.050mm (0.002”). We provide custom thinning and backgrind services for silicon wafers in any quantity, with same-day service available.
We use double pass cutting to provide high precision wafer dicing of both bumped and non-bumped silicon wafers. Performed in a Class 10K cleanroom environment, we optimize our dicing processes to provide optimal yields.
Our method of removing damage from wafers is a process called Chemical Mechanical Planarization (CMP), also often referred to as wafer polishing. Our post backgrind wafer polishing removes between 5 and 10 microns of silicon from the back side of the wafer.
We offer both fully-automated and manual wafer inspection services for full wafers and sawn wafers on dicing frames. We utilize customer wafer maps and/or ink dot recognition, and use image captures to provide immediate feedback, if needed.
Our die sorting capabilities include fully-automated and manual processes, as well as multi die “binning.” Device inverting is available to prepare your project for automated manufacturing. A variety of packaging options and related services are also available.
We specialize in high mix, low volume SMD tape and reel packaging. Our tape and reel service meets EIA standards and can be customized to meet your unique requirements. All reels are 100% inspected prior to shipment.
Back-end Metal Deposition: Creating a completed microchip does not need to be a lengthy or complicated process. Syagrus Systems is a one-stop shop that offers everything you need. Back-end metal deposition, or metallization, is one of the many services we provide to our customers. Our goal is to keep lead times short and the process worry-free.
Performed following the wafer backgrinding process, the SEZ substrate etching process removes silicon from the back of the wafer and also eliminates subsurface microdamage. The etching process results in an ultra-thin wafer with a uniform, with a stress-free surface.
When necessary, Syagrus takes the additional steps of heating the metals so they fuse into the silicon crystal structure. If you are unsure whether annealing is a good choice for your application, our engineers can provide guidance to ensure that your chip performs at its absolute best.
