What it is
How it works
General reference — not yet source-verifiedA mask aligner is a lithography tool that aligns a photomask to a substrate and exposes the substrate through the mask pattern.
Mask aligners are used to transfer patterned features during photolithographic processing.
Where it fits in the process flow
General reference — not yet source-verifiedA mask aligner sits in the lithography portion of the semiconductor process flow.
A mask aligner is used before downstream development and related pattern transfer steps in a wafer fabrication sequence.
Applications
General reference — not yet source-verifiedA mask aligner is used for photolithography on substrates that require contact or proximity exposure of a mask pattern.
A mask aligner supports patterning work in semiconductor and microfabrication processes.
