The GaN free-standing single crystal substrate is a material used to prepare high-performance optoelectronic devices. It is composed of high-purity gallium nitride material without external substrate support.GaN Free-standing Single Crystal Substrate is an independent GaN (GaN) single crystal substrate prepared by homoepitaxial growth technology, without relying on sapphire, silicon carbide and other heterogeneous substrates for support. Its core features are low defect density, high thermal conductivity, and high breakdown voltage, and it is suitable for high-performance optoelectronics (LED/LD), power electronics, high-frequency electronics and other fields.
GaN Free-standing Single Crystal Substrate is a fundamental material for the development of next-generation electronic and optoelectronic devices, offering significant advantages over traditional substrates such as sapphire, silicon carbide (SiC), and silicon. These substrates are made entirely of GaN crystals, eliminating the lattice constant and thermal expansion coefficient mismatch issues common in heteroepitaxial growth on foreign substrates. This consistency significantly reduces defect density, especially threading dislocations, which is critical for achieving high performance and high reliability of GaN-based devices. The demand for GaN Free-standing Single Crystal Substrate is mainly due to its key role in high-power and high-frequency applications, such as RF power amplifiers, high electron mobility transistors (HEMTs), power converters, and laser diodes, which require excellent thermal management and electrical performance. From a classification perspective, 2-inch wafers dominate the market with their higher production maturity and lower cost, with a market share of nearly 84.13% in 2024. 4-inch wafers are gradually being commercialized, especially in the field of high-power and high-frequency electronics, but their yield and cost-effectiveness still need to be further optimized. At the same time, leading global and Chinese companies are actively developing 6-inch self-supporting GaN substrates, aiming to expand their scale in next-generation power electronics and photonic applications. Once technical challenges such as defect density and scalability are overcome, these larger substrates are expected to release economies of scale and enable more efficient GaN device manufacturing. From an application perspective, gallium nitride self-supporting single crystal substrates are mainly used in optoelectronics (including blue/violet/green laser diodes and LEDs), high-frequency radio frequency electronics (such as base station components and satellite communications), and power electronics (such as electric vehicle inverters and industrial power supplies). Among them, optoelectronic applications currently account for 70.06% due to their strict requirements for low dislocation density and high optical performance - and self-supporting GaN substrates have significant advantages over heteroepitaxial solutions in these fields. As GaN power devices further penetrate into electric vehicles, renewable energy and consumer electronics, demand for large-diameter, high-quality self-supporting GaN substrates is expected to continue to grow, driving the industry towards the commercialization of 4-inch and 6-inch wafers. However, the manufacture of gallium nitride self-supporting single crystal substrates faces technical difficulties and high cost challenges. Current production methods include hydride vapor phase epitaxy (HVPE), ammonothermal growth, and sodium flux method. Among them, HVPE technology is still the most commercialized and widely adopted technology due to its high growth rate and scalability.
