The ASML PAS 5500/300 DUV is a deep ultraviolet (DUV) stepper.[1]
What it is
How it works
General reference — not yet source-verifiedA stepper exposes photoresist by illuminating a reticle and imaging the reticle pattern onto a small field on the wafer. A stepper then moves the wafer to the next field and repeats the exposure sequence across the wafer. A lithography system of this class combines an illumination path, projection optics, wafer positioning, mask handling, alignment sensing, and exposure control to place patterns at defined locations on each die.
Where it fits in the process flow
General reference — not yet source-verifiedLithography tools are used after wafer film formation and photoresist coating, and before resist development. Lithography tools work in repeated patterning loops with deposition, etch, implantation, and cleaning steps. Alignment capability is important because each new patterned layer must register to features already formed on the wafer.
Applications
General reference — not yet source-verifiedDeep ultraviolet steppers are used to print device and interconnect patterns in semiconductor fabrication. Deep ultraviolet exposure is used for critical layers where optical imaging and overlay control are central to pattern fidelity. Tools in this class are applied to resist patterning for subsequent etch, implant, or film definition steps across integrated circuit process flows.
