What it is
How it works
General reference — not yet source-verifiedAn i-line stepper projects the image of a reticle onto a wafer through a reduction lens. The wafer is positioned on a stage that exposes a field at a time, then steps to the next location and repeats the exposure. The step-and-repeat architecture allows the reticle pattern to be reproduced across the entire wafer surface.
A stepper exposes the full reticle field at each field location on the wafer. The control system coordinates the exposure sequence, stage stepping, and alignment operations.
Where it fits in the process flow
General reference — not yet source-verifiedPhotolithography steppers sit between the photoresist coating step and the develop and etch steps in wafer fabrication. The stepper exposes the resist, changing its solubility so that the pattern can be developed. After development, the wafer moves to etch and subsequent processing steps.
Steppers of this class are used for the lithography steps that create the conductive, insulating, and semiconducting layers of a device. i-line steppers are commonly applied to mature process technologies and to layers where very high resolution is not the primary requirement.
Applications
General reference — not yet source-verifiedSteppers of this kind are used in both production and research environments for wafer lithography. An i-line stepper is appropriate for device layers that can be patterned with an i-line process.
