晶圆可追溯性的自动识别

竞争激烈的全球半导体ustry demands ever more rigorous control of increasingly complex processes in order to maximize tool utilization and production yield; there is zero margin for error. The need to track wafers throughout back-end processing has never been more vital to profitability.

In-Sight^®1740系列晶圆读卡器通过自动识别具有极高可靠性的晶圆来帮助满足此挑战，以最大限度地减少人类干预的需求并防止工具空闲时间。无论是安装在新设备上还是改装到现有工具上，In-Sight 1740系列读者都可以使100％晶圆可追溯性实现现实。

For more than two decades, Cognex wafer ID systems have set the standard for high read rates and reliability, and the In-Sight 1740 series is no exception. In-Sight 1740 series wafer readers may be small, but they’re packed full of performance. Everything needed to achieve high read rates without compromising reliability is provided in a single compact, self-contained system.

先进的照明系统

With 12 modes of built-in, software-controlled, bright and dark field illumination, In-Sight 1740 series readers can image virtually any ID mark. Super-soft marks, ultra-thin coatings sapphire substrates - the In-Sight 1740 series lighting system is up to these challenges, and many more. Plus, as new wafer processes and coatings are developed, In-Sight 1740 series readers can be extended to meet new imaging challenges with specialized lighting powered by the auxiliary light port.

经过验证的阅读算法

Even the most effective illumination needs advanced ID algorithms to successfully read OCR, T7 Data Matrix, and barcodes on hard to image wafers. At the heart of the In-Sight 1740 series are Cognex reading algorithms developed based on the experience that only comes from having installed over 31,000 wafer ID systems. These algorithms are proven to the most robust, most reliable in the world on ID marks that have been degraded by edge bead, CMP, scribe-on-die patterns, and other conditions.

The effects of wafer processing can impact ID mark quality to such an extent that they resist reading by even the most advanced lighting system and software algorithms. In-Sight 1740 series readers can overcome these visual degradations using automatic image enhancement filters. In the most severe cases, filters are able turn a read failure into a read success while increasing reliability and eliminating the need for a human intervention.

Faster reading performance

The In-Sight 1740 Series reads 40% faster than its predecessor, the best-selling In-Sight 1720 Series. The extra power can also be used to perform more processor intensive image analysis that delivers exceptionally reliable results without increasing overall read times.
