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 275 i-Line is an i-line stepper. The ASML PAS 5500 275 i-Line processes 8 inch wafers.[1]
What it is
How it works
General reference — not yet source-verifiedMask 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-verifiedLithography 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-verifiedSteppers 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.
