What it is

The EV Group IQA 0049 Mask is a mask aligner for lithography.[1]

How it works

General reference — not yet source-verified

A mask aligner positions a photomask relative to a substrate before exposure in a lithography step.

Mask aligners use controlled alignment to register mask features to the wafer surface before optical transfer of the pattern.

Where it fits in the process flow

General reference — not yet source-verified

A mask aligner sits in the front end of the lithography flow, after substrate preparation and before pattern transfer.

The EV Group IQA 0049 Mask is used where mask-to-substrate alignment is required before exposing a patterned image onto the wafer.

Applications

General reference — not yet source-verified

Mask aligners are used for photolithographic patterning on wafers and other flat substrates.

Mask aligners are used in semiconductor processing and in other microfabrication work that depends on aligned exposure through a mask.
