NxQ 8008 CT Series – Scalable, high volume production platform

The NxQ 8000 Production Mask Aligner Integrates the latest in Robotic Automation with a state of the art next generation design from Milara, Inc.

The Dual Arm Robot delivers lightning fast wafer transfer at twice the accuracy of competitors and incorporates a pre-aligner from Logosol which can detect transparent substrates making it ideal for not only silicon, but a wide range of compound semiconductor materials. It is a WTS combination that is by far the best in the industry.

The NxQ 8008 CT Mask Aligner offers industry state of art automated mask loading option with its front load port design which are SMIF load port upgradeable while maintaining the footprint of the tool.

The NxQ 8000 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 0.5um 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 Series Mask Aligner is ideal for Microelectronics, LED / HB LED, 3D IC, SIOP, WLP, 2.5D Interposer, MEMS, BioMEMS, MicroFluidics, Compound Semi, Solar (HCPV), and Optoelectronics applications.
