Quartz Boat Holders

Semicorex Quartz Boat Holders are precision-engineered quartz fixtures designed to securely support quartz wafer boats and silicon wafers during high-temperature semiconductor manufacturing processes. Fabricated from high-purity fused quartz, these components provide exceptional thermal stability, chemical purity, and dimensional accuracy, making them essential for diffusion, oxidation, annealing, and other critical thermal processes.

Semicorex manufactures high-quality Quartz Boat Holders using precision fabrication and strict quality control, delivering customized solutions that meet the demanding standards of semiconductor and photovoltaic production.

Precision Support for Stable Wafer Processing

In semiconductor fabrication, maintaining precise wafer positioning throughout thermal processing is essential for achieving consistent device performance and high manufacturing yields. Quartz Boat Holders serve as the structural support for quartz wafer boats, ensuring that wafers remain securely aligned while passing through high-temperature furnace processes.

Manufactured from premium fused quartz rods and quartz plates, these holders are fabricated through precision slotting, flame welding, grinding, and surface finishing processes. The result is a rigid and dimensionally accurate structure capable of maintaining stability even under continuous exposure to elevated temperatures.

Unlike conventional materials, fused quartz offers an extremely low coefficient of thermal expansion, allowing the holder to resist deformation during rapid heating and cooling cycles. Its high purity also minimizes particle generation and metallic contamination, protecting sensitive silicon wafers throughout the manufacturing process.
