개요

The Czochralski (CZ) process grows single-crystal silicon ingots by slowly pulling a seed crystal from a melt of ultra-pure polysilicon at 1,414 degrees C. These monocrystalline ingots are sliced into wafers that form the substrate for virtually all integrated circuits, microprocessors, and memory chips. The process requires silicon purity of 99.9999999% (9N) — one of the most demanding purification challenges in any industry. Modern 300 mm wafers can yield over 1,000 processor dies each.

화학 공정

Electronic-grade polysilicon is melted in a quartz crucible at 1,414 degrees C under argon atmosphere. A seed crystal is dipped into the melt and slowly pulled upward (1-2 mm/min) while rotating, growing a cylindrical single crystal (ingot) of 200-300 mm diameter and up to 2 meters long. The ingot is sliced into 0.7 mm thick wafers using diamond wire saws.

SiO₂ + C → Si + CO₂ (metallurgical grade, 98%)
Si + 3HCl → SiHCl₃ + H₂ (purification)
SiHCl₃ + H₂ → Si (EG-Si, 9N) + 3HCl (Siemens CVD)
Si(liquid) → Si(single crystal) (CZ growth at 1,414 degrees C)

원자재

  • Electronic-grade polysilicon (EG-Si) — Siemens process (SiHCl₃ + H₂ → Si + HCl) (Ultra-pure silicon feedstock (9N purity))
  • Argon gas (Ar) — Air separation (Inert atmosphere)
  • Quartz crucible (SiO₂) — Fused quartz manufacturing (Melt containment)

최종 제품

  • Silicon wafers — Integrated circuits, microprocessors, memory, solar cells (200/300 mm diameter, <100> or <111> orientation)

Environmental Impact

The Siemens process for polysilicon production is extremely energy-intensive (100-200 kWh/kg Si). Chlorosilane chemistry generates HCl and SiCl₄ byproducts. Wafer cutting wastes approximately 50% of the ingot as kerf loss. Recycling of silicon scraps is increasingly practiced.
