Photovoltaic & Semiconductor

Process Characteristics

In photovoltaic and semiconductor manufacturing, ingot furnaces, crystal pullers and diffusion furnaces run continuously above 1300 °C. Temperature sensors must therefore combine high-temperature capability, thermal-shock resistance and measurement accuracy.

Common Challenges

• Furnace temperature stays above 1300 °C for long periods; long-term stability is essential.
• Ingot casting and crystal growth involve steep gradients, demanding accurate and fast response.
• Large numbers of insulating supports and spacers are required, with strict demands on temperature resistance and cleanliness.
• Production is continuous, so sensors must resist thermal shock and premature failure.
