In-Sight 1750 Wafer and Panel Reader
Automatically reads every wafer ID, even the faintest marks, using multi-mode lighting for 100% traceability without slowing production.
Reliable and precise wafer traceability throughout production
The global semiconductor industry runs on speed, precision, and zero tolerance for error. Wafers – thin, round slices of silicon used to make integrated circuits – may be small, but they’re packed full of performance. This requires accurate tracking from front-end fabrication until they are diced. To meet rising demand for higher tool usage, rigorous control, and greater production yield, manufacturers need reliable wafer traceability systems to maintain profitability and product quality.
To keep pace, advanced machine vision optimizes the process to ensure codes are read quickly and accurately, enabling accurate wafer traceability.
Advanced barcode scanners solve even the toughest wafer identification challenges
Wafers are marked with laser-etched ID codes – either alphanumeric characters or Data Matrix symbols – on a small area of the silicon disk, enabling identification through multiple processing stages until they are diced. But reliably reading these tiny codes poses significant challenges.
Degraded marks, reflective surfaces, small etched characters, and cleanroom constraints make consistent wafer ID imaging difficult for traditional systems – disrupting tool alignment, quality control, and overall production efficiency.
Advanced barcode scanning provides the precision and reliability manufacturers need – consistently decoding wafer IDs to ensure accurate processing, rapid troubleshooting, and end-to-end traceability.

Leading the way in wafer ID accuracy
Designed for high-speed, precision-driven semiconductor environments, Cognex solutions, including the In-Sight 1750 Series, enables 100% wafer traceability, delivering fast, reliable decoding of virtually any ID mark, including alphanumeric and 2D Data Matrix codes.
These compact, cleanroom-compatible systems combine OCR capabilities, advanced algorithms, robust optics, and flexible lighting to simplify and strengthen wafer ID:
- High-resolution imaging captures very small characters on reflective wafer surfaces, aided by an enhanced 2MP sensor and expanded 38 mm field of view for greater coverage
- Built-in multi-mode illumination (bright field and dark field) optimizes contrast for low-contrast or degraded marks, with enhanced RGB lighting improving results on substrates like silicon, GaN, SiC, sapphire, and glass
- AI-driven mark adaptation adjusts to changes caused by masking, etching, or photolithography, reducing no-reads, minimizing assists, and maximizing uptime
Plus, Cognex offers flexible support options, on-site, on-line, or on-demand and backed by a global network of vision experts.
