Provisional entry — research in progress
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.
The ASML PAS 5500 / 250 C is an i-line stepper used for semiconductor photolithography. The ASML PAS 5500 / 250 C processes 8-inch wafers.[1][2][3]
What it is
How it works
General reference — not yet source-verifiedA stepper projects a patterned reticle image onto a wafer in repeated exposures across the substrate.
An i-line lithography tool uses i-line illumination for photoresist exposure in the patterning step.
Where it fits in the process flow
General reference — not yet source-verifiedThe ASML PAS 5500 / 250 C i-Line sits in the front-end lithography portion of the wafer fabrication flow.
The ASML PAS 5500 / 250 C i-Line is used after photoresist coating and before resist development and subsequent pattern transfer steps.
