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.

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.

Silicon carbide substrate is a compound semiconductor single crystal material composed of two elements, carbon and silicon. It has the characteristics of large bandgap, high thermal conductivity, high critical breakdown field strength, and high electron saturation drift rate.

Semiconductor technology has been the backbone of modern civilization, fundamentally transforming the way we live, work, and interact with the world. It has enabled unprecedented advancements in various fields including information technology, energy, telecommunications, and healthcare. From the microprocessors that power our smartphones and computers, to the sensors in medical devices, and the power electronics in renewable energy systems, semiconductors are at the core of nearly every technological innovation of the past century.

Carbon fiber (CF) is a type of fibrous material that contains over 95% carbon.

In the chemical vapor deposition (CVD) process, the gases used mainly include reactant gases and carrier gases. Reactant gases provide atoms or molecules for the deposited material, while carrier gases are used to dilute and control the reaction environment. Below are some commonly used CVD gases:
