ASML is one of the world’s leading manufacturers of chip-making equipment. Headquartered in Veldhoven, the Netherlands, ASML employs more than 14,000 people.
The PAS 5500/100D i-line stepper is designed for mass production at 0.4 μm and achieves extremely high throughput while maintaining the utmost versatility with its variable Numerical Aperture (NA). This stepper extends i-line’s capability for manufacturing multiple generations of sub-half-micron design rules by optimizing both depth of focus and resolution for critical process layers.
