NxQ 8000 Manual Load Mask Aligner
The NxQ 8000 ML Mask Aligner and Front to Back Overlay Inspection System integrates state-of-the-art alignment stage design. Equipped with the revolutionary UV-LED exposure optics, the printing performance is far superior to that of a mercury bulb source and lasts 7-10 years in an HVM environment. The NxQ 8000 ML alignment stage utilizes the latest in linear motion technology. With encoder feedback loops measuring actual stage position, not motor position, the vision system is not limited by the hardware, allowing for alignment accuracies of less than 0.5µm 3 sigma. This accuracy is achieved using our Quadcam Microscope with 5x objectives, delivering an ideal combination of ‘Magnification,’ ‘Field of View,’ and ‘Depth of Focus.’
The NxQ 8000 ML features a manual load system, allowing operators to load wafers or pieces efficiently without requiring robotic automation. This approach is ideal for facilities prioritizing flexibility and simplicity in their workflow.
The versatility of the NxQ 8000 ML makes it the preferred choice of manufacturing facilities and R&D Centers around the world for a wide range of technologies.
The NxQ 8000 ML Mask Aligner is ideal for Microelectronics, 3D IC, WLP, 2.5D Interposer, MEMS, and Solar (HCPV) applications.
