High-Purity Opaque Quartz Shield & Shutter For MOCVD

1. Technical Specifications

We provide high-precision machining based on your technical drawings to ensure a perfect fit with your specific equipment models.

2. Core Application Fields

● MOCVD Process Protection: Serving as essential internal shields/liners to protect the reaction environment.

● Semiconductor Epitaxy: Used as high-precision shutters for flow and temperature stabilization during thin-film growth.

● Wide-Bandgap Semiconductor Manufacturing: Compatible with high-demand environments for GaN and other advanced materials.

3. Why Choose VETEK Quartz Solutions?

● Superior Thermal Radiation Management: Our milky white quartz contains a high density of micro-bubbles that effectively scatter and block high-temperature thermal radiation (>1000°C). It absorbs visible and near-infrared light from heating elements and converts it into far-infrared radiation, ensuring highly uniform heating.
● Contamination Control & Easy Maintenance: As a sacrificial or replaceable inner liner, the Quartz Shield keeps the reaction chamber clean by preventing byproduct deposition on expensive chamber walls and heaters. These parts can be regenerated through wet cleaning (such as SPM+DHF solutions) or easily replaced to ensure high wafer yields.
● Extreme Chemical Resistance: VETEK quartz is engineered to withstand frequent thermal cycling and resist corrosion from metal organics (like TMGa) and hydrides (like AsH₃).
● Precision Process Control: Our Quartz Shutters maintain high dimensional stability under infrared or filament heating. Their low thermal inertia allows for rapid mechanical response, enabling precise "atomic level" growth control and preventing cross-contamination during multi-wafer or multi-process switching.
● Cost-Effective Alternative: For projects with strict budget requirements, our quartz products provide a reliable entry point compared to coated graphite, offering essential protection and functionality for MOCVD systems.
