MONOCRYSTALLINE AND POLYCRYSTALLINE SILICON
We offer a full range of ingots and wafers of monocrystalline and polycrystalline silicon with an electrical resistivity of 0,0001 - 100 000 ohm * cm. (High-resistance silicon has electrical resistivity of 10 000 - 100 000 ohm * cm.)
Silicon can be made by methods: Czochralski (CZ) or Float Zone (FZ).
The ingots and the plates may have the shape: cylindrical - 2 "to 8" (50.8 mm - 203.2 mm) or square - 6 "to 8" (152.4 mm - 203.2 mm).
Conductivity type: P (boron doped or neutron-doped) and N (doped with phosphorus, arsenic, antimony or neutron-doped).
