Genuine 12/14-inch Silicon Wafer — Engineering Sample (Display Only)

Genuine Silicon Wafer (Not a Replica)

Own a real piece of semiconductor manufacturing — a 12-inch or 14-inch silicon wafer from engineering samples or scrap lots. Each wafer shows intricate circuit layouts and produces rainbow-like reflections under different lighting angles (optical diffraction/thin-film effects).

Why You’ll Love It

• Real silicon wafer (display-grade collectible, not a model)

• 12-inch or 14-inch diameter — impressive presence on a desk or in a display case

• Unique pattern every time — designs vary by batch and wafer type

• Iridescent color shifts — best viewed under a focused lamp or directional light

• Clear display stand included — ready to showcase out of the box

Best For

• Classroom demonstrations & STEM education

• Lab / office / studio display

• Collectors of semiconductor & computing memorabilia

• A distinctive gift for engineers, makers, and tech enthusiasts

Important Notes (Please Read)

• This is scrap / engineering sample material.

• Display / education / non-functional use only. It cannot be used for packaging, production, or functional electronic applications.

• Minor micro-scratches, small marks, or handling traces may occur and are generally unavoidable in surplus wafers.

• Random selection: pattern/layout and reflective color appearance vary by wafer and lighting angle. Photos are examples of possible looks.

• Any process-node/origin details are stated by the source. We are not affiliated with or endorsed by any foundry or brand.

Display Tips (For the Best Look)

Use a desk lamp or spotlight from the side/top and slowly rotate the wafer. Dark backgrounds emphasize the rainbow effect; light backgrounds emphasize fine circuit detail.
