The ventilation quartz inner tube is designed for precise gas flow control and thermal isolation within semiconductor furnace systems. Made from high-purity fused quartz, it exhibits excellent resistance to thermal shock, chemical corrosion, and particle contamination—making it ideal for demanding high-temperature processes.

As an inner component of double-tube furnace structures, this quartz tube directs process gases uniformly over wafer surfaces while maintaining separation from the furnace wall. Its optimized geometry enhances laminar flow, reduces boundary layer effects, and supports consistent deposition or diffusion results across 200 mm wafers.

Optimizing Wafer Yield Using Ventilation Quartz Inner Tubes

Ventilation quartz inner tubes are essential components in semiconductor processing, designed to ensure stable and uniform gas flow within high-temperature furnaces. By promoting consistent exposure to process gases, these tubes help maintain thermal uniformity across all wafers, reducing defects and improving overall yield.

Made from high-purity fused quartz, the inner tubes resist chemical corrosion, thermal shock, and particle contamination, protecting sensitive wafers during diffusion, oxidation, and CVD processes. Proper installation, regular maintenance, and precision design further enhance gas distribution, minimize wafer-to-wafer variation, and ensure repeatable, high-quality results.

Using ventilation quartz inner tubes effectively allows semiconductor fabs to achieve higher yields, maintain process consistency, and uphold stringent cleanroom standards.
