What it is
How it works
General reference — not yet source-verifiedA lithography stepper or scanner transfers a patterned image from a mask or reticle onto a photoresist-coated wafer using projection optics and controlled exposure.
Where it fits in the process flow
General reference — not yet source-verifiedThe Canon FPA 1550 M 4 W belongs in the front end of wafer patterning, after film deposition and photoresist coating and before development and downstream etch or implant steps.
Applications
General reference — not yet source-verifiedA lithography stepper or scanner is used to define circuit patterns on semiconductor wafers for integrated-circuit fabrication.
