The Canon FPA 2500 i 3 Fine Pattern is a fine pattern aligner. The Canon FPA 2500 i 3 Fine Pattern is categorized as a lithography tool. The Canon FPA 2500 i 3 Fine Pattern dates from 1994.[1][2]
What it is
How it works
General reference — not yet source-verifiedA fine pattern aligner typically consists of a light source, a condenser optical system, a mask holder, a precision stage for the substrate, and a viewing system for alignment. The machine aligns the mask and substrate using micrometer adjustments and then exposes the substrate to a controlled dose of light through the mask.
Where it fits in the process flow
General reference — not yet source-verifiedIn a semiconductor fabrication process, the fine pattern aligner is used after the substrate has been cleaned and coated with a photosensitive resist. The alignment and exposure step defines the pattern in the resist. Following exposure, the substrate moves to developing and subsequent process steps such as etching or deposition.
Applications
General reference — not yet source-verifiedFine pattern aligners are applied in the manufacture of integrated circuits, microelectromechanical systems, and other devices where precise pattern transfer is required.
