Sub micron void sensitivity


IRQuickScanTM Void Detection System

The IRQuickScanTM (IRQS) System utilizes a newly-developed, proprietary infrared detection scheme coupled with the powerful ClarityTM software platform to quickly characterize a variety of substrates for internal defects.

The IRQS System images any bonded wafer instantaneously, providing a detailed analysis that includes the location and classification of all defects associated with the bonding process. The BTBP Clarity SoftwareTM proprietary Artificial Intelligence engine, which is part of all BTBP Clarity products, locates all artifacts, classifies them, and produces a KLARF-like file, called the ClarityRF file.

Here is an output from the IRQS System taken when imaging a bonded pair of silicon wafers with embedded metal pads, which exhibits voids and inclusions from the bonding process as well as the strain fields associated with bonding.

In addition, the IRQS System is able to provide the strain field signature on metalized production test wafers as shown here.

Of course the IRQS System is an ideal production tool for the SiC chip manufacturing environment since it allows detailed analysis of substrate crystal defects and associated strain fields as shown here.

The core value which drives the design of our systems is EASE OF USE. But we didn't stop there, in fact we started with our proprietary patented imaging technology and built a full system around it. Then we added our core expertise in Artificial Intelligence.
