Porous Graphite Barrels

Semicorex Porous Graphite Barrels play a critical role in the crystal growth process of silicon carbide (SiC) semiconductors. Given the unique requirements of SiC single-crystal growth, the thermal insulation and heat distribution properties of graphite barrels are essential in determining the quality and yield of the final crystal. Our high-performance porous graphite barrels are specifically engineered to meet these stringent demands, offering superior thermal control, high purity, and excellent mechanical properties.

 

 

High Porosity with Interconnected Pores

Our porous graphite barrels have a high porosity level with well-connected pores. This unique characteristic facilitates uniform radial temperature in the furnace, which is crucial for minimizing thermal gradients and enhancing crystal yield. By promoting consistent thermal conditions, our barrels contribute to the reduction of defects and improvements in crystal uniformity.

 

Thermal Insulation 

Semicorex porous graphite barrels deliver exceptional insulation, dramatically reducing heat loss and maintaining optimal growth environments. This enhanced thermal efficiency not only maximizes energy utilization but also ensures superior crystal quality and higher yields.

 

Ultra Purity

Contaminants can critically compromise the performance of SiC wafers. Our porous graphite barrels are subjected to a rigorous purification process, achieving ash content levels below 5 ppm. This unparalleled purity effectively eliminates contamination risks, guaranteeing an exceptionally clean crystal growth environment that meets the demands of high-end semiconductor applications.

 

High Strength 

Our porous graphite barrels are engineered with outstanding mechanical strength, ensuring remarkable durability and resilience against thermal stress during crystal growth. Furthermore, the material’s exceptional machinability enables ultra-thin processing, offering unmatched design flexibility and optimizing space efficiency in high-precision semiconductor manufacturing.

Due to their outstanding thermal properties, ultra-high purity, and superior mechanical strength, our porous graphite barrels are widely used in the SiC single-crystal growth process. Their ability to improve thermal uniformity and reduce contamination directly contributes to higher crystal quality and production yield, making them an indispensable component in the semiconductor industry.
