The document describes the Neutronix-Quintel NXQ8000 series of mask aligners. The NXQ8000 has a flexible, modular, and scalable platform that can process wafers from R&D to pilot production to fully automated processes. It uses electromagnetic linear motors and high precision encoders for accurate wafer positioning. The system offers both manual and automatic wafer loading/unloading, as well as optional features like backside alignment and DUV exposure optics.

NXQ sets the industry standard for Air
bearing leveling which provides the most
control and lowest force leveling for
fragile and ultra thin wafers and high
value product wafers!
Low friction ball seat provides an
excellent seal when vacuum is applied to
perform precise wedge error
compensation
The “air bearing” floats the chuck for
precise leveling.
Flexures prevent Z-axis shifting
The lock ring holds the piston tightly
after leveling.
