Photovoltaic Quartz Boat Brackets

Semicorex photovoltaic quartz boat brackets are precision-manufactured from high-purity photovoltaic-level quartz materials through processes including slotting, welding and frosted finishing. They are typically used with automatic loading equipment to stably and safely place quartz boats and their loaded wafers inside quartz furnace tubes, enabling the large-scale high-temperature wafer processing, including diffusion, oxidation, annealing and LPCVD and PECVD.

The advantages of Semicorex photovoltaic quartz boat brackets

1. Superior thermal resistance

Semicorex photovoltaic quartz boat brackets boast superior thermal resistance and are able to operate stably in the high-temperature furnaces for a long time. Semicorex photovoltaic quartz boat brackets can maintain their structural integrity when the temperature is up to 1200 ℃ , which effectively avoids the risk of deformation and melting caused by high temperatures.

2. Exceptional thermal shock resistance

Semicorex photovoltaic quartz boat brackets offer stable support for wafer thermal processing because of their low thermal expansion coefficient, which allows them to endure drastic temperature changes without cracking.

3. Reliable chemical resistance

Semicorex photovoltaic quartz boat brackets have high inertness to acidic and alkaline gases as well as different dopants, and they can function steadily in complex high-temperature corrosive environments thanks to their dependable chemical resistance.

4. Extreme cleanliness performance

Manufactured from photovoltaic-level quartz, Semicorex photovoltaic quartz boat brackets feature high purity and low metallic impurity content, thus effectively eliminating wafer contamination from impurity release in thermal processing.

Applications in the photovoltaic industry

1. Diffusion process

Semicorex photovoltaic quartz boat brackets are well-suited for the applications in the diffusion process, such as phosphorus diffusion and boron diffusion, and can facilitate the reaction between wafers and doping gases to create PN junctions.

2. Oxidation process

Semicorex photovoltaic quartz boat brackets are suitable for the use of oxidation processing conditions, which can contribute to the uniform formation of oxide layers on the wafer surface.

3. Annealing process

Semicorex photovoltaic quartz boat brackets are applied to hold the wafer boat and for annealing the wafer under high-temperature conditions, which helps to eliminate internal stress in wafers and improve the crystal quality of wafers.

4. LPCVD and PECVD process

Semicorex photovoltaic quartz boat brackets can support quartz boats and wafers in the low-pressure or plasma-enhanced chemical vapor deposition conditions, facilitating the formation of thin films on wafer surfaces.

Benefiting from their excellent performance, Semicorex photovoltaic quartz boat brackets can ensure the stable position of quartz boats and their loaded wafers in the challenging operating environment. They contribute to the uniform distribution of heat and gas flow within the quartz furnace tubes and guarantee the consistency of the thermal processing, thereby greatly improving the performance and production efficiency of solar cells.
