Senshuo technology silicon Rod customization process
Production process
Charging furnace
Polysilicon material and impurities are put into a quartz crucible, and the type of impurities depends on the N or Ptype of resistance.
Charging process
The furnace is closed and pumped into high purity Argon to maintain a certain pressure range. The graphite heater power supply is turned on and the polysilicon material is melted by heating 1420°。
Necking growth
After the temperature of the silicon melt stabilized, the seed crystal was immersed into the silicon melt slowly. Because of the thermal stress of the seed crystal in contact with the silicon melt field, dislocation would occur in the seed crystal.
Free-standing growth
After growing the thin neck, the
temperature and the pulling speed are lowered, so that the crystal gradually increases to the required size.
Equal diameter growth
After the neck and shoulder are long, the diameter of the Rod can be kept positive or negative 3MM by adjusting the speed and temperature.
Final Cooling
The diameter of the crystal rod is gradually reduced until it becomes a cusp to separate from the liquid level. The process is called tail growth.
CZ and FZ
Almost 90% of the silicon used in the semiconductor industry is grown by czochralski method。
