China epitaxy growth Manufacturers, Suppliers, Factory

The silicon carbide industry involves a chain of processes that include substrate creation, epitaxial growth, device design, device manufacturing, packaging, and testing. In general, silicon carbide is created as ingots, which are then sliced, ground, and polished to produce a silicon carbide substrate.

The growth of GaN epitaxy on GaN substrate presents a unique challenge, despite the material’s superior properties when compared to silicon. GaN epitaxy offers significant advantages in terms of band gap width, thermal conductivity, and breakdown electric field over silicon-based materials. This makes the adoption of GaN as the backbone for the third generation of semiconductors, which provide enhanced cooling, lower conduction loss, and improved performance under high temperatures and frequencies, a promising and crucial advancement for the photonic and micro-electronic industries.

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.

In modern electronics, optoelectronics, microelectronics, and information technology fields, semiconductor substrates and epitaxial technologies are indispensable. They provide a solid foundation for manufacturing high-performance, high-reliability semiconductor devices. As technology continues to advance, semiconductor substrates and epitaxial technologies will also progress, bringing new breakthroughs and developments to the future of the semiconductor industry.
