By 2027, solar photovoltaic (PV) will overtake coal as the world's largest installed capacity. The cumulative installed capacity of solar PV nearly triples in our forecast, growing by nearly 1,500 gigawatts over this period, and will surpass natural gas by 2026 and coal by 2027.

As the world looks for new opportunities in semiconductors, gallium nitride continues to stand out as a potential candidate for future power and RF applications. However, for all the benefits it offers, it still faces a major challenge; there are no P-type (P-type) products. Why is GaN touted as the next major semiconductor material, why is the lack of P-type GaN devices a major drawback, and what does this mean for future designs?

Silicon carbide has a large number of applications in emerging industries and traditional industries. At present, the global semiconductor market has exceeded 100 billion yuan. It is expected that by 2025, the global sales of semiconductor manufacturing materials will reach 39.5 billion US dollars, of which the silicon carbide semiconductor market is expected to reach a market size of 2.5 billion US dollars in 2025. At the same time, silicon carbide is still the material with the best application performance in traditional ceramics, refractory, high temperature, grinding and other fields.

Within the silicon carbide (SiC) industry chain, substrate suppliers hold significant leverage, primarily due to value distribution. SiC substrates account for 47% of the total value, followed by epitaxial layers at 23%, while device design and manufacturing constitute the remaining 30%. This inverted value chain stems from the high technological barriers inherent to substrate and epitaxial layer production. Three major challenges plague SiC substrate growth: stringent growth conditions, slow growth rates, and demanding crystallographic requirements. These complexities contribute to increased processing difficulty, ultimately resulting in low product yields and high costs. Furthermore, the epitaxial layer’s thickness and doping concentration are critical parameters directly impacting the final device performance.

Semicorex offers high-quality thermal insulation felt and glass-like carbon coating.

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:
