$699.99

Up for grabs is an authentic cleanroom-direct lot of 25 full-size 300mm (12-inch) patterned semiconductor silicon wafers, complete with their industrial clear transport carrier case!
These are not cheap mirror-finish test blanks. Every single wafer in this cassette is etched with intricate microchip circuit die patterns that explode into vibrant, holographic rainbow diffraction reflections under direct light. As shown in the photos, sample wafers feature factory laser-etched SEMI tracking numbers and 2D matrix barcodes along the alignment edge (see photos to inspect details for yourself).
Whether you're looking to frame these into high-end tech wall art, part them out individually for huge resale returns, use them for lab/display collections, or showcase the full cassette as the ultimate high-tech conversation piece, this full-capacity case is a rare find.
