Wafers are essential raw materials for integrated circuits, power devices, and semiconductor discrete devices. Over 90% of integrated circuits are manufactured using high-purity, high-quality wafers. The quality and supply capacity of these wafers within the industry are directly linked to the overall performance and competitiveness of integrated circuits. In this discussion, we will introduce the wafer manufacturing process in detail.

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.

As a unit of length, Angstrom (Å) is ubiquitous in integrated circuit manufacturing. From precise control of material thickness to miniaturization and optimization of device size, the understanding and application of Angstrom scale is the core to ensure the continuous development of semiconductor technology.

Silicon carbide (SiC) is an inorganic substance. The amount of naturally occurring silicon carbide is very small. It is a rare mineral and is called moissanite. Silicon carbide used in industrial production is mostly artificially synthesized.

Both are N-type semiconductors, but what's the difference between arsenic and phosphorus doping in single-crystal silicon? In single-crystal silicon, arsenic (As) and phosphorus (P) are both commonly used N-type dopants (pentavalent elements that provide free electrons). However, due to differences in atomic structure, physical properties, and processing characteristics, their doping effects and application scenarios differ significantly.

Specialty graphite is graphite with carbon mass fraction greater than 99.99%, also known as "three high graphite" (high strength, high density, high purity). It is characterized by high strength, high density, high purity, high chemical stability, high thermal and electrical conductivity, high temperature resistance, radiation resistance, strong lubrication and easy processing. Isostatic graphite belongs to specialty graphite.
