· Nice example of what wafers look like prior to 'microchips' (circuits) being made onto them. · Amazing instance of semiconductor technology growth history. · It has been optically polished with supper smooth mirror surface · Great to be used as gift, display object, exhibition, educating demonstration, testing, decoration or your collection. Here is spec information for the wafers: Methos/Type/Dopent: CZ / N / Phosphorous, Orientation: <100>, Diameter: 99.2-100.8 mm, Thickness: 500-550um, Resistivity: 2-4 Ohm cm. Methos/Type/Dopent: CZ / N / Phosphorous, Orientation: <100>, Diameter: 125 mm, Thickness 625+/-25 um, Resistivity: 0.008-0.02 Ohm cm. Methos/Type/Dopent: P/Boron, Orientation: <100>, Diameter: 150 mm, Thickness 625+/- 50 um, Resistivity: 1-25 Ohm cm. Methos/Type/Dopent: P/Boron, Orientation: <100>, Diameter: 200 mm, Thickness 710+/- 15 um, Methos/Type/Dopent: P/Boron, Orientation: <100>, Diameter: 300 mm, Thickness 750+/- 25 um, The Wafer is very fragile, a broken wafer can be dangerous due to the sharp edges can cause injuries. Consider it as thin glassware, handle and display it with care. Keep away to the children. We will pack it very well for transport. Please click here to see other wafers in our store.
