What it is

The ASML PAS 5500 275 i-Line is an i-line stepper used for photolithography in semiconductor manufacturing.^[1]^[2]

The ASML PAS 5500 275 i-Line handles 8-inch wafers.^[1]

The ASML PAS 5500 275 i-Line uses ASML's PAS 5500 platform architecture.^[1]^[2]

How it works

General reference — not yet source-verified

Mask aligners expose a photoresist-coated wafer to ultraviolet light through a photomask, transferring the mask pattern onto the wafer.

The ASML PAS 5500 275 i-Line is a stepper, meaning it projects the mask image onto only a portion of the wafer at a time and steps the wafer to expose the entire surface in a grid pattern.

Where it fits in the process flow

General reference — not yet source-verified

Lithography tools are used to define circuit patterns on the wafer, a step that occurs after the wafer has been cleaned and coated with photoresist in a track system.

After exposure and development, the wafer moves to etch and deposition steps to transfer the pattern into underlying layers.

Applications

General reference — not yet source-verified

Steppers such as the ASML PAS 5500 275 i-Line are used to print critical layers in integrated circuit manufacturing, where overlay accuracy and resolution are required.

The ASML PAS 5500 275 i-Line, as an i-line tool, is suited for producing devices with medium- to high-resolution feature sizes typical of i-line lithography.
