Used TOPCON Vi-4202 #293660827 for sale

TOPCON Vi-4202 is a powerful and versatile mask and wafer inspection equipment. It is commonly used for checking the quality of semiconductor wafers and photomasks used in their manufacture. The system combines advanced optical magnification, image processing capabilities and a wide variety of software-controlled test protocols, enabling users to view both the top and bottom surfaces of etched circuits and structures with unprecedented accuracy. Vi-4202 uses a double-sided mirror optical microscope which provides up to 500x magnification and 0.5μm resolution for mask inspection, and up to 600x magnification and 1μm resolution for wafer inspection. It features a robust 12" auto-focus program and a full set of programable, automated image-processing functions for more accurate results. TOPCON Vi-4202 also has a range of built-in analysis features such as advanced line-of-sight inspection, pattern recognition, alignment control, 3D inspection and a wide range of measurement capabilities. It also provides support for the specification of both variable and fixed test positions and allowances, to help users accurately measure thin-film structures. The unit's dual-direction image technology helps reduce operator fatigue and provides for both top and bottom surface imaging in just a fraction of the time required by manual Inspection systems. It is capable of supporting multiple-batch inspections, while its fully automated auto-focus functions enhance repeatability and reduce human error. Vi-4202 is also highly reliable and resilient due to its robust and protective housing, as well as the strong airflow created by its direct view and light path. Its two-dimensional vibration control machine helps reduce disturbance from external sources, providing steadier, more consistent imaging. Also, TOPCON Vi-4202's user-friendly controls and intuitive software make it extremely easy to use. It can be easily operated via its Touch Screen control panel, and its comfortable ergonomic design helps reduce operator stress. Overall, Vi-4202 is an advanced and reliable mask and wafer inspection tool that delivers superior results, seamlessly integrating sophisticated optical technology with image processing capability for superior performance and accuracy.
