PAS 5500 300 C Wafer
What it is
General reference — not yet source-verifiedA wafer stepper is a photolithography exposure tool used in semiconductor manufacturing. A wafer stepper projects a patterned image from a reticle onto photoresist on a wafer, exposing one field at a time while moving the wafer between exposures.
How it works
General reference — not yet source-verifiedA wafer stepper exposes resist-coated wafers by optically reducing and imaging a reticle pattern onto the wafer surface. A wafer stepper repeats the exposure across the wafer in a step-and-repeat sequence so that many die images can be placed at defined field locations. A wafer stepper relies on alignment between wafer marks and reticle patterning to position each exposure accurately.
Where it fits in the process flow
General reference — not yet source-verifiedA wafer stepper sits in the lithography portion of wafer fabrication after photoresist coating and soft bake. A wafer stepper is used before resist development, pattern transfer, and subsequent etch or implant steps that use the printed resist image as a mask.
Applications
General reference — not yet source-verifiedWafer steppers are used to print patterned layers for integrated circuit manufacturing and related microfabrication. Wafer steppers support repeated patterning tasks in flows that build device features, interconnect levels, contact openings, and other lithographically defined structures.
