The Ultratech 1000 Family is a family of photolithography step-and-repeat wafer steppers.[1]
The Ultratech 1000 Family is part of Ultratech's 1X stepper line and uses a Wynne Dyson optical design.[1]
A mask aligner or stepper transfers a circuit pattern from a photomask onto a photosensitive wafer surface using controlled optical exposure.
A step-and-repeat tool exposes one field at a time and then advances the wafer to the next field for repeated pattern transfer across the wafer.
The Ultratech 1000 Family belongs to a lithography stage that defines patterns early in the wafer process flow before later pattern transfer and device formation steps.
The Ultratech 1000 Family is used for semiconductor lithography applications.[1]
