Semiconductor heating scenarios

The monocrystalline silicon growth process is the process of converting the polycrystalline silicon raw material into monocrystalline silicon, and the commonly used methods are CZ method (CZ method) and zone melting method (FZ method). Resistance/radio frequency heating is adopted for direct pulling method, and thermal stability is guaranteed by ± 0.5 ℃ temperature control and 0.1% accuracy power supply with millisecond level response; The zone melting rule uses high frequency induction (10-50kHz) to produce 15kW/cm? With the above power density, the double-closed loop control maintains the accuracy of 0, 2mm molten zone and drives the crystal to grow stably at 0.5-2mm/min. Both processes realize ordered arrangement of silicon atoms through precise energy control to meet the quality requirements of semiconductor crystal.
