This page was generated automatically from cited public sources and hasn't completed the full research pass yet. Every specification shown carries its source; more detail is added as research completes.
What it is
How it works
General reference — not yet source-verifiedA stepper exposes a wafer by repeating a projection step across its surface, using a reticle and a reduction or unit-magnification lens system to image the pattern.
The substrate is positioned on a precision stage that moves between exposures, and an alignment system registers each field to previous layers.
Where it fits in the process flow
General reference — not yet source-verifiedThe stepper is used after the wafer has been coated with photoresist and before the resist is developed.
After exposure, the wafer moves to a develop module, then to etch or ion-implant steps for pattern transfer.
Applications
General reference — not yet source-verifiedSteppers are employed in semiconductor manufacturing to define transistor and interconnect features at the required critical dimensions.
Advanced packaging, microelectromechanical systems, and other micro-fabrication flows also use steppers for high-resolution patterning on a variety of substrate sizes.
