The process of isostatic graphite manufacturing is Selecting raw materials, Blending, Molding, Isostatic pressing, Carbonization, Graphitization. 

Semicorex's SiC crystal growth furnace component, the porous graphite barrel, will bring three major benefits and can effectively strengthen the competitiveness of domestic SiC substrates:

The third generation of semiconductor materials AlN belongs to the direct bandgap semiconductor, its bandwidth of 6.2 eV, with high thermal conductivity, resistivity, breakdown field strength, as well as excellent chemical and thermal stability, is not only an important blue light, ultraviolet materials, or electronic devices and integrated circuits, important packaging, dielectric isolation and insulation materials, especially for high-temperature high-power devices. In addition, AlN and GaN have a good thermal match and chemical compatibility, AlN used as GaN epitaxial substrate, can significantly reduce the defect density in GaN devices, improve device performance.

SiC substrate can have microscopic defects, such as Threading Screw Dislocation (TSD), Threading Edge Dislocation (TED), Base Plane Dislocation (BPD), and others. These defects are caused by deviations in the arrangement of atoms at the atomic level. SiC crystals may also have macroscopic dislocations, like Si or C inclusions, micropipe, hexagonal voids, polymorphs, etc. These dislocations are typically large in size.

The annealing process, also known as Thermal Annealing, is a crucial step in semiconductor manufacturing.
