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.
What it is
General reference — not yet source-verifiedMask aligners are photolithography tools used to transfer patterns from a photomask onto a photosensitive substrate, typically a semiconductor wafer. Mask aligners operate by bringing a mask into proximity or contact with the substrate and exposing it to ultraviolet (UV) light.
How it works
General reference — not yet source-verifiedA mask aligner typically contains a UV light source, a collimation optical system, a mask holder, a substrate chuck with alignment stages, and an exposure controller. The operator loads a substrate, aligns the mask relative to the substrate using manual or semi-automatic controls, and then exposes the photoresist-coated substrate to a controlled dose of UV light through the mask.
The OAI Model 200, as a tabletop mask aligner, is designed for manual or semi-automatic operation in a compact footprint. The system incorporates proven industrial components to achieve reliable exposure results.
