Gallium oxide (Ga2O3) has emerged as a promising material for various applications, particularly in power devices and radio frequency (RF) devices. In this article, we explore the key opportunities and target markets for gallium oxide in these domains.

Behind every high-temperature process in wafer manufacturing lies a silent yet crucial player: the wafer boat. As the core carrier that directly contacts the silicon wafer during the wafer processing, its material, stability, and cleanliness are directly related to the final chip yield and process stability. Among various carrier materials, silicon carbide (SiC) boats are gradually replacing traditional quartz solutions, becoming the preferred solution for advanced processes and high-end equipment.

Isostatic pressing technology is a critical process in the manufacturing of isostatic graphite, largely determining the performance of the final product. As such, comprehensive research and optimization of isostatic graphite production remain essential focal points in the industry.

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.

Silicon material is a solid material with certain semiconductor electrical properties and physical stability, and provides substrate support for the subsequent integrated circuit manufacturing process. It is a key material for silicon-based integrated circuits. More than 95% of semiconductor devices and more than 90% of integrated circuits in the world are made on silicon wafers.

The basic crystal unit cell of monocrystalline silicon is the zinc blende structure, in which each silicon atom bonds chemically with four neighboring silicon atoms. This structure is also found in monocrystalline carbon diamonds.
