Recently, our company announced that the company has successfully developed a 6-inch Gallium Oxide single crystal using the casting method, becoming the first domestic industrialized company to master the 6-inch Gallium Oxide single crystal substrate preparation technology.

The third-generation wide bandgap semiconductor materials, such as Gallium Nitride (GaN) and Silicon Carbide (SiC), are renowned for their exceptional optoelectronic conversion and microwave signal transmission capabilities. These materials meet the demanding requirements of high-frequency, high-temperature, high-power, and radiation-resistant electronic devices. Therefore, they have vast application prospects in new-generation mobile communications, new energy vehicles, smart grids, and LED technologies. The comprehensive development of the third-generation semiconductor industry urgently requires breakthroughs in key core technologies, continual advancement in device design and innovation, and a resolution to import dependencies.

The first generation of semiconductor materials is mainly represented by silicon (Si) and germanium (Ge), which began to rise in the 1950s. Germanium was dominant in the early days and was mainly used in low-voltage, low-frequency, medium-power transistors and photodetectors, but due to its poor high temperature resistance and radiation resistance, it was gradually replaced by silicon devices in the late 1960s. Silicon is still the main semiconductor material in the field of microelectronics due to its high technological maturity and cost advantages.

Silicon carbide (SiC) ceramic materials possess a range of excellent properties, including high-temperature strength, strong oxidation resistance, superior wear resistance, thermal stability, low thermal expansion coefficient, high thermal conductivity, high hardness, thermal shock resistance, and chemical corrosion resistance. These characteristics make SiC ceramics increasingly applicable in various fields such as automotive, mechanical and chemical industries, environmental protection, space technology, information electronics, and energy. SiC ceramics have become an irreplaceable structural ceramic material in many industrial sectors due to their outstanding performance.

The recent announcement of the 2024 Nobel Prize in Physics has brought unprecedented attention to the field of artificial intelligence.

Etching is a critical step in chip manufacturing, used to create minute circuit structures on silicon wafers.
