I. Core Technical Challenges in Liquid-Phase Sintering of Advanced Ceramics

Advanced ceramics (such as alumina, Silicon Nitride, silicon carbide, zirconia, etc.) require extremely high uniformity, density, and purity in their microstructure. Liquid-phase sintering, as a core method for achieving low-temperature densification, still faces three key issues in practical application that directly constrain product performance and industrial application.

With the rapid advancement of microelectronics technology, electronic systems and components are moving toward miniaturization, Lightweight design, integration, higher reliability, and greater power output. The increasing complexity of devices places higher demands on the heat dissipation of substrates and packaging materials. Consequently, aluminum nitride (AlN) substrates, known for their high thermal conductivity, have become a "star material" in the field of heat dissipation substrates. In the new energy vehicle sector, they can even replace aluminum oxide substrates, demonstrating broad application prospects.

Hexagonal Boron Nitride (h-BN) possesses a series of excellent properties. As a primary structural ceramic material, it has been successfully applied in multiple fields. With extensive research, the functional properties of h-BN have also been gradually developed, showing broad application prospects in areas such as new energy and electronics. Furthermore, for certain harsh service environments requiring integrated structural and functional properties, h-BN is also an ideal candidate material.

High-purity alumina ceramics are important ceramic materials primarily composed of high-purity, ultrafine alumina as the raw material and α-Al2O3 as the main crystal phase. Due to their excellent properties such as high mechanical strength, high hardness, high-temperature resistance, and corrosion resistance, high-purity alumina ceramics are widely used in various fields including machinery, electronics, integrated circuits, and medicine.

The Critical Role and Safety Hazards of Specialty Gas Cabinets in Semiconductor Manufacturing

In the highly advanced field of semiconductor manufacturing, specialty gases are rightly known as the "lifeblood of chip fabrication." They are essential for key processes such as etching, deposition, and doping of chips. The gas cabinets, which store and supply these critical gases, are undoubtedly vital pieces of equipment. The consequences of a leak from a gas cabinet can be catastrophic.

In recent years, high-speed development has been observed in fields such as electric vehicles, electric locomotives, semiconductor lighting, aerospace, and satellite communication. The electronic components in these applications operate with high currents, at high temperatures, and high frequencies. To ensure the stability of these components and circuits, higher demands are placed on chip carriers. Ceramic substrates, boasting excellent thermal properties, microwave performance, mechanical properties, and high reliability, find widespread use in these areas.

High-purity alumina ceramic is an important ceramic material primarily composed of high-purity, ultrafine alumina as the main raw material, with α-Al2O3 as the principal crystalline phase. Due to its excellent properties such as high mechanical strength, great hardness, high-temperature resistance, and corrosion resistance, high-purity alumina ceramics are widely used in machinery, electronics, integrated circuits, medicine, and other fields.

In semiconductor manufacturing, the ion implantation process precisely introduces dopants into silicon wafers to modify their electrical properties. This critical step, however, involves numerous highly toxic and hazardous gases. A leak of these gases could lead to severe consequences. Advanced gas monitoring technologies and equipment form a critical barrier, acting as unseen sentinels to ensure safety.
