Precision Quartz Process Fixture Ring with Radial Support Ribs for Semiconductor Equipment

The precision quartz process fixture ring is a custom-manufactured semiconductor component designed for supporting, positioning, isolating or protecting parts inside thermal processing and semiconductor production equipment.

Its annular structure includes multiple radial support ribs extending between the inner and outer circular sections. This reinforced design helps distribute mechanical loads, improve overall rigidity and reduce deformation while keeping the component relatively lightweight.

The product can be manufactured from fused quartz according to customer drawings, physical samples or equipment specifications. Outer diameter, inner opening, thickness, rib quantity, mounting features and surface condition can all be customized.

製品仕様

The values above are general manufacturing options. Final specifications should be confirmed through the customer’s technical drawing.

代表的なアプリケーション

Custom quartz fixture rings may be used in:

• Semiconductor thermal processing equipment
• Wafer diffusion systems
• 酸化炉
• CVD and deposition equipment
• Quartz furnace assemblies
• Wafer support and positioning mechanisms
• High-temperature treatment systems
• Process chamber assemblies
• Semiconductor equipment replacement parts

The final design should be selected according to the operating temperature, mechanical load, equipment structure and process environment.

Radial Reinforcement Design

The radial ribs are an important structural feature of this quartz fixture.

Compared with a simple flat quartz ring, the reinforced structure can help:

• Improve rigidity across the annular surface
• Reduce local stress concentration
• Distribute the load more evenly
• Maintain shape during handling and installation
• Support larger customized diameters
• Improve stability during repeated thermal cycles

The number, spacing, width and height of the ribs can be adjusted according to the actual equipment requirements.

Fused Quartz Material Performance

熱安定性

Fused quartz has very low thermal expansion compared with many conventional glass and ceramic materials. This characteristic helps the fixture maintain dimensional stability during heating and cooling.

High-Temperature Compatibility

Quartz components are widely used in semiconductor thermal equipment because they can withstand many elevated-temperature process conditions.

The allowable working temperature depends on the quartz grade, component design, loading method and process cycle.

耐薬品性

Quartz provides good resistance to many acids and process chemicals. This makes it suitable for applications where corrosion resistance and cleanliness are important.

Clean Processing Performance

Properly manufactured and cleaned quartz components can help reduce contamination inside semiconductor and precision process equipment.

Optical and Surface Options

Depending on the manufacturing process, quartz fixtures can be supplied with transparent, translucent, ground or locally polished surfaces.

Custom Manufacturing Options

The following features can be customized:
