Czochralski process, Czochralski method, Czochralski crystal growth
A method of growing large size, high quality semiconductor crystal by slowly lifting a seed crystal from a molten bath of the material under careful cooling conditions.

The most widely used technique for making single-crystal silicon, in which a seed of single-crystal silicon contacts the top of molten silicon.

As the seed is slowly raised, atoms of the molten silicon solidify in the pattern of the seed and extend the single-crystal structure.

extractive metallurgy, extraction metallurgy; process metallurgy, processing metallurgy
Metallurgy which is concerned with the extraction of metals from their ores, refining, and adapting them for use.

Metals are extracted from ores in three primary ways:

  1. Dry processes; such as, smelting, volatilization, or amalgamation; which is treatment with mercury.
  2. Wet processes, involving chemical reactions.
  3. Electrolytic processes, which work on the principle of eletcrolysis using electricity conducted by a solution or melt to effect chemical changes.

float-zone process, foat zone process, floatzone process
A method of growing a large-size, high-quality crystal whereby coils heat a polycrystalline ingot placed on top of a single-crystal seed.

As the coils are slowly raised the molten interface beneath the coils becomes single crystal.
