Making outline
- Assemble filtered near-UV contact-frame board exposure with physical pressure plate/holder, separate layer photomask tooling, fiducial registration, manual source/shutter and independent resist-band dose/geometry comparison
- Detailed procedure and acceptance remain unresearched.
What remains unresolved
- Manufacture, quantities, suitability and complete inventory remain unreviewed.
- Current memory-first method needs source and compatibility review.
Canonical reuse assessment
"Distinct contact-board apparatus from DUV wafer projection; wavelength/resist/feature suitability unqualified."
