Photovoltaic Quartz Boats

Tailored Performance for Extreme Process Environments

(1)Thermodynamic Stability at 1100°C - 1200°C

Photovoltaic thermal processes demand the highest material integrity. VETEK utilizes high-purity fused quartz to ensure our products withstand continuous operation at extreme temperatures ranging from 1100°C to 1200°C.

 ● Thermal Shock Resistance: Featuring an ultra-low coefficient of thermal expansion, the boat body maintains its geometric integrity even when subjected to frequent and rapid temperature cycling during automated loading.

 ● Structural  Durability: Superior thermal stability prevents sagging or deformation over long-term use, ensuring the sustained accuracy of robotic wafer handling (transfer precision).

(2)Sub-millimeter Precision Slot Control

To achieve perfectly uniform distribution of process gases (such as high-purity nitrogen or oxygen) across the wafer surface, we apply precision engineering to every slot:

 ● Airflow Optimization: The perfect equidistant slot design guarantees flow field consistency, resulting in highly uniform PN junction formation on the wafer surface.

 ● Stress Reduction: Specially fire-polished or polished slot edges significantly minimize the risk of micro-cracking at the wafer perimeter, directly improving breakage control.

(3)Ultra-High Purity for Guaranteed Yield

Material purity is a decisive factor in carrier lifetime. VETEK quartz boats ensure peak performance through:

 ● Premium Material Selection: Extremely low metallic impurity content prevents secondary contamination of the silicon wafers during high-temperature diffusion.

 ● Chemical Inertness: Our boats remain chemically stable in complex doping gas environments, resisting reactions with process gases to maintain a pristine production environment.
