Used KLA / TENCOR 2435 Viper #9399301 for sale

KLA / TENCOR 2435 Viper is an automated optical inspection equipment specifically designed for the inspection of masks and wafers. It has a unique 3-in-1 design that enables it to simultaneously inspect masks, cross-wafers, and flat-wafer patterns. The system utilizes two sensor heads which allow it to image both the top and bottom of the wafer. The more powerful bottom head provides a deep UV laser exposure, while the secondary top head focuses on reflectivity and color. The unit's high scan speeds enable it to pass through an 8-inch wafer in under 10 seconds. With its integrated digital high-resolution imaging machine, 3D reconstruction capabilities and high-end image management systems, it is capable of capturing up to 1 million spots per second and detecting defects down to the sub-micron range. It features an advanced image-processing algorithm that can detect even the smallest defects, such as scratches, pores and particles. Furthermore, the tool is equipped with a sophisticated wafer-alignment feature that can account for even the slightest distortion in the wafer's surface. Furthermore, asset automation supports a variety of production steps, helping to minimize errors and significantly increase throughput. This includes integrated recipe management, pattern stitching, die sort and dice map adjustment tools. It is also equipped with an efficient non-destructive overlay feature, which allows it to measure overlay accuracy without destroying the wafer's integrity. The model is supported by an extensive suite of optimizing software tools. These include defect review software, wafer adapter software, alignment software, die sort and mapping tools, which all contribute to the automated production of masks and wafers. It also includes advanced data analysis tools that provide detailed results, aiding in product optimization and validation. In conclusion, KLA 2435 Viper is an advanced mask and wafer inspection equipment that is designed to deliver superior performance and reliability. Its automated features make it suitable for high-volume, as well as high-precision, production environments. Its ability to detect even the smallest of defects, in combination with its advanced suite of software tools, ensures that it can meet the stringent quality requirements of the semiconductor and semiconductor packaging industries.
