High Resistivity Float Zone Silicon by Topsil

N-type phosphorous doped Silicon approaching 10,000 ohm-cm in 1-1-1 and 1-0-0 orientations up to 100 mm diameter is now available, frequently from stock .

Float zone Silicon from Topsil is in the Galileo spacecraft now orbiting Jupiter; it is in the Hubble Space Telescope in orbit around the Earth; it will be in the Genesis solar wind sampling project.

Valley Design is compiling possibly the most complete stock list of Float Zone Silicon in ingot form, as-cut wafers, etched wafers, lapped, and single and double sided polished wafers.

Total capabilities include prime wafers, monitor wafers, reclaimed wafers, junk wafers, 300 mm wafers, shaped wafers, thin wafers, bonded wafers, CZ and “you-name-it” wafers.
