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 global acceptance of electric vehicles gradually increases, Silicon Carbide (SiC) will encounter novel growth opportunities in the forthcoming decade. It is anticipated that manufacturers of power semiconductors and operators in the automotive industry will participate more actively in the construction of this sector’s value chain.

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.

Silicon carbide (SiC) is highly favored in the semiconductor industry for its excellent physical and chemical properties. However, the high hardness and brittleness of SiC pose considerable challenges to its processing.

Silicon carbide (SiC) crystal growth furnaces are the cornerstone of SiC wafer production. While sharing similarities with traditional silicon crystal growth furnaces, SiC furnaces face unique challenges due to the material’s extreme growth conditions and complex defect formation mechanisms. These challenges can be broadly categorized into two areas: crystal growth and epitaxial growth.

Gallium Nitride (GaN) is an important material in semiconductor technology, known for its exceptional electronic and optical properties. GaN, as a wide-bandgap semiconductor, has a bandgap energy of approximately 3.4 eV, making it ideal for high-power and high-frequency applications.
