Quartz Boat

Semicorex Quartz Boat is a critical wafer-holding component used in semiconductor and photovoltaic manufacturing processes. Designed to securely support silicon wafers during high-temperature thermal treatments, it plays an essential role in maintaining process stability, wafer cleanliness, and production consistency. Manufactured from high-purity quartz glass, the Quartz Boat is widely used in diffusion, oxidation, annealing, and other thermal processing applications where contamination control and temperature uniformity are essential.

At Semicorex, Quartz Boat is fabricated using premium quartz glass rods and quartz glass plates through precision slotting, welding, grinding, and surface-finishing processes. The result is a durable and dimensionally accurate carrier capable of operating reliably in demanding furnace environments.

Precision Construction for Reliable Wafer Handling

A Quartz Boat consists of carefully assembled quartz glass components that form a rigid structure capable of holding multiple wafers in precise positions. The slots integrated into the side plates are engineered to maintain consistent wafer spacing, ensuring optimal gas flow and uniform thermal exposure throughout the process cycle.

The structural design minimizes wafer movement during loading, unloading, and thermal processing. Accurate slot geometry helps prevent wafer contact, reducing the risk of mechanical damage and particle generation. This precision is particularly important as wafer diameters continue to increase and process tolerances become more stringent.

High-Purity Quartz Material Advantages

Quartz glass is one of the most widely used materials in semiconductor thermal processing due to its unique combination of thermal, chemical, and purity characteristics.

Key material benefits include:

Excellent High-Temperature Resistance: Suitable for continuous operation in furnace environments exceeding 1000°C.

Outstanding Thermal Stability: Maintains dimensional accuracy under repeated heating and cooling cycles.

Low Contamination Risk: High-purity quartz minimizes impurities that could affect wafer quality.

Superior Corrosion Resistance: Compatible with a wide range of process gases and chemical environments.

Low Thermal Expansion: Reduces stress and deformation during temperature fluctuations.

These properties make quartz an ideal material for critical wafer-handling applications in cleanroom manufacturing environments.

Optimized for Thermal Process Performance

The performance of a thermal process depends not only on furnace design but also on the quality of the wafer carrier. Quartz Boat are engineered to promote uniform heating and efficient gas distribution throughout the wafer load.

Proper spacing between wafers allows process gases to flow evenly across wafer surfaces, supporting consistent diffusion, oxidation, or annealing results. The open-frame structure helps maintain a stable thermal environment while minimizing temperature variations between wafers.
