What it is
General reference — not yet source-verifiedThe SUSS MicroTec MA 6 Mask is a mask aligner used in photolithography to transfer circuit or pattern features from a photomask to a wafer by contactless or proximity alignment and exposure.
How it works
General reference — not yet source-verifiedA mask aligner holds a wafer and a photomask in a controlled optical and mechanical arrangement, aligns their patterns with microscope-assisted viewing, and then exposes the wafer so the mask pattern can be transferred into a resist-coated surface. In this class of tool, alignment accuracy and stable illumination are central to the process.
Where it fits in the process flow
General reference — not yet source-verifiedA mask aligner sits in the lithography section of the fabrication flow, after surface preparation and resist coating and before development and pattern transfer into the underlying film stack or substrate. It is used before downstream etch, deposition, or lift-off steps that rely on the resist pattern.
Applications
General reference — not yet source-verifiedMask aligners are used for photolithographic patterning in semiconductor and related microfabrication work, including device prototyping, process development, and production of structures that do not require the resolution of stepper-based projection lithography.

Frequently asked questions
What kind of tool is this class of machine?General reference — not yet source-verified
It is a lithography mask aligner used to align a photomask to a resist-coated substrate and expose the resist with the mask pattern.
What process step does it perform?General reference — not yet source-verified
It performs optical pattern transfer by exposing photoresist through an aligned mask, creating a patterned resist image for later fabrication steps.
Where does this class fit in microfabrication?General reference — not yet source-verified
It is used early in the patterning sequence, after resist preparation and before development and downstream pattern transfer operations.
What kinds of substrates are processed on this class of tool?General reference — not yet source-verified
Such systems are used on substrates that need precisely aligned optical patterning, especially in semiconductor, microdevice, and precision microfabrication workflows.
What is the main function of alignment in this class of machine?General reference — not yet source-verified
Alignment places the mask pattern accurately relative to features already present on the substrate so the new exposure lands in the intended location.
