Used SEMILAB / SDI WT-2000PVN #293810216 for sale

SEMILAB / SDI WT-2000PVN mask and wafer inspection equipment is an opto-electronic imaging platform designed for automated inspection of masks, wafers, reticles, and overlay targets. It offers superior optical performance, automated precision alignment, and high speed automated image analysis. The system is equipped with a CCD sensor array, four fluorescent lights, and an adjustable stage with motorized movement. The imaging CCD sensor array has a high pixel resolution, excellent charge-coupled device (CCD) read noise, low dark current, and wide dynamic range, providing clear and accurate results. The fluorescent light sources, together with the stage illumination, offer a luminance up to 200,000 foot-lamberts for excellent image contrast. The automated precision alignment ensures accurate image overlay results. SDI WT-2000PVN has automated image analysis capabilities with dedicated software for defect detection, CD measurement, chart analysis, and other image-based applications. The image analysis functions are designed to detect small defects and variations, including rotating patterns, isolate dimension measurements, and generate 3D surface measurements. The analysis can be run in stand-alone mode or with customized scripts for advanced applications. The unit also includes an advanced software interface for efficient operation, which includes pre-set criteria for automatic image analysis and defect detection. The user-friendly interface has embedded calibration functions, pre-set analysis criteria, automated traceability, and powerful database and report functions for comprehensive documentation. For advanced applications, users can use scripts or other coding languages for customized analysis. SEMILAB WT-2000 PVN is designed for applications requiring high throughput, high accuracy, and repeatability, and provides excellent performance over a wide range of imaging tasks. This machine is suitable for defect review, design rule checks, reticle and overlay inspection, as well as process control in the semiconductor, electronics, and medical industry.
