DirectScan™
DirectScan System*. This system* *combines our proprietary eProbe hardware and various proprietary software to fundamentally reimagine e-beam systems to help identify systematic failures inline before they occur. Conventional e-beam inspectors operate by rastering across regions of interest, capturing complete images, then performing die-to-die comparisons to identify defective pixels. Our eProbe tool instead functions as a contactless electrical tester. It is designed to jump from one device under test (“DUT”) to another, measuring voltage contrast at specific pads of interest, while skipping dielectric regions entirely. Our DirectScan system is provided to customers under a license/lease arrangement or as a hardware sale. The DirectScan system contains the following components.
| ● | Proprietary Software – Our Fire™ software module is designed to analyze IC product layout features to help determine which parts of the product layout to inspect. Our Exensio Characterization module has been designed to analyze the billions of measurements collected using the eProbe tool. As part of the system offering, we generally use the Characterization module to provide analysis services to our customers, which typically includes a summary of our findings and recommendations. |
| ● | eProbe Non-Contact E-Beam Tool – Our eProbe e-beam tools are designed for contactless measurement of product layout. The fourth generation tool, the 450, includes advances in beam vector targeting and higher signal-to-noise (SNR) for enhanced defect sensitivity, higher throughput, enhanced tool matching, and better inspection control for more stable performance necessary for deployment in high-volume manufacturing (HVM). Our eProbe tools are designed to use our secureWISE network for us to provide secure remote equipment support and maintenance to customers. |
