Defect-free epitaxial growth occurs when one crystal lattice has nearly identical lattice constants to another. Growth happens when lattice sites of the two lattices at the interface region are approximately matched, which is possible with a small lattice mismatch (less than 0.1%). This approximate matching is achieved even with elastic strain at the interface, where each atom is slightly displaced from its original position in the boundary layer. While a small amount of strain is tolerable for thin layers and even desirable for quantum well lasers, the strain energy stored in the crystal is generally lowered by the formation of misfit dislocations, which involve a missing row of atoms in one lattice.

In the semiconductor industry, quartz is widely used, and high-purity quartz products are even more important consumables in wafer production. The production of silicon single crystal crucibles, crystal boats, diffusion furnace core tubes, and other quartz components must use high-purity quartz glass products.

​As the world searches for new opportunities in the semiconductor field, Gallium Nitride (GaN) continues to stand out as a potential candidate for future power and RF applications. However, despite its numerous benefits, GaN faces a significant challenge: the absence of P-type products. Why is GaN hailed as the next major semiconductor material, why is the lack of P-type GaN devices a critical drawback, and what does this mean for future designs?

In semiconductor manufacturing, ion implantation involves using high-energy accelerators to inject specific impurity atoms, such as arsenic or boron, into a silicon substrate.

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?

Epitaxial wafer process is a critical technique used in semiconductor manufacturing. It involves the growth of a thin layer of crystal material on top of a substrate, which has the same crystal structure and orientation as the substrate. This process creates a high-quality interface between the two materials, allowing for the development of advanced electronic devices.
