Horizon 4000 Series: The 4090u (micro) and the 4090f are the Company's primary offerings in the Horizon 4000 Series of wafer probers. This product line is positioned to satisfy high-volume semiconductor manufacturing applications. The Horizon 4000 Series provides many advanced automation capabilities, including automatic probe-to-pad-alignment, in-process inspection and optical character recognition (OCR), and a temperature-controlled chuck top, providing the ability to maintain precisely a customer-selected wafer temperature during testing. The 4090f prober has a unique wafer handing system that allows wafers to be probed which could not normally be handled on an automated prober. The Horizon Series utilizes the Company's EGCommander system software, which allows significant application and customer driven customization of the wafer prober and is compatible with the standard MS-DOS operating system. The user interface features color graphics, touch screen programming, probing recipes, control maps, and real-time maps. The Horizon 4000 Series probers feature a distributed multiple processor architecture to maximize productivity and expandability.
