C/C composite heaters

C/C composite heaters are usually positioned around a crucible situated at the center of crystal growth furnaces, supplying uniform heat to the semiconductor materials inside the crucible through resistance heating. When the C/C composite heaters are energized, the carbon fibers and matrix can generate heat thanks to the resistance effect. This heat is transferred to semiconductor materials in the crucible through thermal conduction and radiation, raising them to the temperature required for crystal melting. To ensure the more consistent and effective temperature distribution, multiple C/C composite heaters can be combined to create the layered heating structure for the large crystal growth furnaces.

C/C composite heaters can provide precise control over the process conditions for uniform melting of semiconductor materials and the temperature gradient required for crystal growth, thereby significantly reducing the impact of temperature fluctuations on crystal quality. Therefore, the hot zone exhibits a uniform and stable temperature distribution inside the high-temperature crystal furnaces. This improved temperature distribution helps to cultivate high-quality, low-defect monocrystalline silicon products, which significantly optimizes the electrical and mechanical properties of the crystal. Under the action of C/C composite heater, the melting cycle of semiconductor materials can be effectively shortened, thereby accelerating the crystal growth rate and helping to improve overall production efficiency.

The thermal field system for semiconductor crystal growth is composed of C/C composite heaters, along with core components including crucibles, flow guide tubes, thermal insulation sleeves, and crucible shafts.
