Precision quartz components: Polishing, welding & machining.

Overview

[Supporting Advances in Front-End Semiconductor Manufacturing with High-Precision Quartz Glass Processing]

We are a specialized engineering firm featuring high-precision "polishing," "welding," and "precision grinding & machining" of quartz glass and other specialty glass materials used in front-end semiconductor manufacturing equipment.

We have a proven track record of supplying high-quality components for front-end equipment—including deposition (CVD/PVD), etching, diffusion/thermal processing, and cleaning—where extreme precision and cleanliness are required.

■ Our Core Strengths & Key Technologies
• High-Precision Polishing: Ultra-precision polishing meeting strict flatness and surface roughness specifications.
• Complex Welding & Joining: Expert glass welding ensuring excellent airtightness and thermal resistance.
• Precision Grinding: High-precision dimensional control, capability for complex channel structures, and micro-machining.

■ Main Products & Components
• Process Chamber Components (Quartz windows, rings, flanges, etc.)
• Quartzware & Fixtures for Wafer Processing (Bell jars, tubes, boats, etc.)
• Custom & Made-to-Order Fabrication (From single-piece prototypes based on drawings)

We provide flexible solutions tailored to your needs, from design consultation and prototyping to mass production. If you are looking to improve component precision or searching for a partner capable of complex quartz processing, please feel free to visit our booth.
