Quartz Support Ring

Semicorex 12-inch Quartz Support Ring is designed to work seamlessly with the lift shaft mechanism inside epitaxial reactors. During operation, as the lift shaft descends, the three strategically positioned support tabs on the ring engage with the lift pins. These tabs effectively hold and guide the lift pins, allowing them to rise and gently elevate the wafer from the susceptor surface. This controlled lifting action prepares the wafer for safe and efficient transfer by a robotic arm, minimizing the risk of mechanical damage or misalignment.

The Quartz Support Ring features a carefully optimized circular geometry to match 12-inch wafer dimensions, ensuring uniform support and alignment. The three support tabs are precisely positioned and machined to interact accurately with the lift pins, providing consistent lifting performance across repeated cycles. Smooth surface finishing reduces particle generation and enhances cleanliness, which is essential for maintaining high device yields.

Key Features and Benefits

High Purity Quartz Material: Minimizes contamination risks and supports ultra-clean processing environments.

Thermal Stability: Maintains structural integrity under high-temperature epitaxial conditions.

Precision Alignment: Ensures accurate positioning of wafers for reliable robotic handling.

Optimized Support Tab Design: Enables smooth coordination with lift shaft and pins for controlled wafer lifting.

Low Particle Generation: Polished surfaces reduce the likelihood of particle shedding, protecting wafer quality.

Durability and Longevity: Resistant to thermal shock and chemical corrosion, extending service life.

Application Scenario

In single-wafer epitaxy systems, precise wafer handling is critical to maintaining process consistency and yield. The Quartz Support Ring acts as a transitional support structure during wafer transfer. When the lift shaft lowers, the support tabs hold the lift pins in position, allowing them to elevate the wafer from the process surface. This ensures that the robotic arm can access and retrieve the wafer without interference, improving automation efficiency and reducing handling errors.
