Compression molding, isostatic pressing, and rod extrusion are the three most common methods for producing graphite rods, similar to those used for creating graphite tubes.

C/C composite is a carbon-carbon composite material made of carbon fibers as reinforcement and carbon as matrix through processing and carbonization, with excellent mechanical and high-temperature resistance properties. The material was initially used in aerospace and special fields, and with the maturity of the technology, it has been gradually used in photovoltaic, automotive, lithium battery, medical devices and other fields.

Recently, the semiconductor industry has continued to pay increasing attention to Gallium Nitride (GaN) technology. Due to its excellent electronic properties, Gallium Nitride devices have important applications in many high-tech fields:

The fabrication of semiconductor devices primarily encompasses four types of processes: (1) Photolithography (2) Doping Techniques (3) Film Deposition (4) Etching Techniques The specific techniques involved include photolithography, ion implantation, rapid thermal processing (RTP), plasma-enhanced chemical vapor deposition (PECVD), sputtering, and both dry and wet etching methods.

Defect-free epitaxial growth occurs when one crystal lattice has nearly identical lattice constants to another. Growth happens when lattice sites of the two lattices at the interface region are approximately matched, which is possible with a small lattice mismatch (less than 0.1%). This approximate matching is achieved even with elastic strain at the interface, where each atom is slightly displaced from its original position in the boundary layer. While a small amount of strain is tolerable for thin layers and even desirable for quantum well lasers, the strain energy stored in the crystal is generally lowered by the formation of misfit dislocations, which involve a missing row of atoms in one lattice.

The three primary methods used in monocrystalline silicon manufacturing are the Czochralski (CZ) method, the Kyropoulos method, and the Float Zone (FZ) method.
