What it is

The ASML PAS 5500 / 250 C i-Line is a lithography stepper for semiconductor photolithography.[3]

The ASML PAS 5500 / 250 C i-Line processes 8-inch wafers.[2][4][5][3]

How it works

General reference — not yet source-verified

A 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-verified

The 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.

Applications

The ASML PAS 5500 / 250 C i-Line is used for semiconductor pattern definition on 8-inch wafers.[2][4][5][3]
