Description
At Semixlab, we specialize in providing high-purity fused quartz products essential for semiconductor manufacturing. Our high purity quartz boats are precision-engineered to meet the rigorous demands of today's wafer processing technologies. These quartz wafer carriers are critical for ensuring the integrity and quality of semiconductor wafers during high-temperature and chemical processes.
The Role of High Purity Quartz Boats in Wafer Processing
Quartz wafer boats are indispensable tools in a variety of semiconductor fabrication steps. These quartz boats serve as carriers for silicon wafers, holding them securely and uniformly during high-temperature processes like diffusion, oxidation, and chemical vapor deposition (CVD).
The primary uses include:
●Thermal Processes: Securely holding wafers during high-temperature treatments like annealing and oxidation. Our quartz annealing boats ensure uniform heat distribution, which is vital for creating consistent and high-quality silicon dioxide layers.
●Diffusion: Transporting wafers into and out of diffusion furnaces, where controlled doping is performed. The inert nature of quartz prevents contamination of the wafers.
●CVD: Acting as a wafer boat bracket to hold wafers in place during the deposition of thin films, ensuring even and uniform film growth across the wafer surface.

Specifications
Material and Physical Properties
Our quartz boats for semiconductor wafer processing are crafted from high-purity fused quartz. This material is chosen for its exceptional physical properties that are ideal for the semiconductor industry.
| Property | Value |
| Material | High-purity Fused Quartz (SiO₂) |
| Purity | > 99.995% |
| Softening Point | Approximately 1600°C |
| Coefficient of Thermal Expansion | 5.5×10−7/°C (at 20-320°C) |
| Thermal Conductivity | 1.38 W/m·K |
| Chemical Inertness | Highly resistant to most acids and alkalis (except hydrofluoric acid) |
| Thermal Shock Resistance | Excellent |
These properties make fused quartz the superior material for wafer carriers. Its high thermal stability prevents deformation at extreme temperatures, and its low thermal expansion coefficient minimizes stress on the wafers, preventing cracking or warping. The exceptional chemical inertness ensures no contaminants are introduced to the delicate wafer surface, which is a common problem with less pure materials.
