The so-called granular float zone process constitutes a further development of the conventional float zone process and opens interesting technological perspectives in the special performance wafers market.
The alternative float zone process involves melting a polycrystalline silicon ingot zone by zone with an induction coil; the narrow molten zone is then brought into contact with a seed crystal.
It is a monocrystalline silicon grown by the Float Zone process with a bulk resistivity from 8000 [ohm]-cm to 30,000 [ohm]-cm.
