Introducing CO₂ into the dicing water during wafer cutting is an effective process measure to suppress static charge buildup and lower contamination risk, thereby improving dicing yield and long-term chip reliability.

We’ve all felt that moment of panic. Your phone battery is at 5%, you have minutes to spare, and every second plugged in feels like an eternity. What if the secret to ending this anxiety lies not in a completely new chemistry, but in reimagining a fundamental material within the battery itself? For two decades at the forefront of tech, I’ve seen trends come and go. But the buzz around Porous Graphite feels different. It isn't just an incremental step; it represents a fundamental shift in how we approach energy storage design.

Quartz devices play a critical role in solar cell manufacturing, offering exceptional thermal resistance, chemical purity, and structural stability required in high-temperature processes. From quartz diffusion tubes and crucibles to quartz boats and furnace components, these high-purity materials are essential for achieving optimal efficiency in diffusion, CVD, and wet etching steps.

The Dechuck principle of the Electrostatic Chuck is a key part of its workflow that involves electrostatic force elimination and wafer release mechanisms.

In the growth of SiC and AlN single crystals using the physical vapor transport (PVT) method, crucial components such as the crucible, seed holder, and guide ring play a vital role. As depicted in Figure 2 [1], during the PVT process, the seed crystal is positioned in the lower temperature region, while the SiC raw material is exposed to higher temperatures (above 2400 ℃).

In the process of growing silicon carbide (SiC) crystals via the Physical Vapor Transport (PVT) method, the extreme high temperature of 2000–2500 °C is a “double-edged sword” — while it drives the sublimation and transport of source materials, it also dramatically intensifies impurity release from all materials within the thermal field system, especially trace metallic elements contained in conventional graphite hot-zone components. Once these impurities enter the growth interface, they will directly damage the core quality of the crystal. This is the fundamental reason why tantalum carbide (TaC) coatings have become a “mandatory option” rather than an “optional choice” for PVT crystal growth.
