State-of-the-Art Semiconductor Quartz Rings & Precision Components
In modern integrated circuit (IC) manufacturing, semiconductor quartz rings play an indispensable role in maintaining process uniformity, wafer integrity, and plasma containment. As an industry-leading semiconductor quartz products manufacturer, Southeast Quartz crafts high-purity focus rings, edge rings, insulation rings, and chamber shield rings tailored for etching, diffusion, oxidation, and chemical vapor deposition (CVD) equipment.
Our quartz components are fabricated from premium grade synthetic and natural fused silica. This guarantees minimal trace metal impurities (such as Fe, Cu, Na, and K < 0.1 ppm), preventing ionic contamination on silicon wafers during sub-nanometer node processing. With outstanding plasma corrosion resistance and near-zero coefficient of thermal expansion, our quartz rings withstand rigorous plasma etch chemistry and cyclic thermal shocks.

View Details →Why Semiconductor Fabs Rely on High-Purity Quartz Rings
In critical fab operations—including dry plasma etching, PECVD, LPCVD, RTP, and wet chemical cleaning—quartz rings ensure electrical isolation and uniform gas distribution across wafers.
Extreme Environment Resistance & Purity Integrity
Semiconductor manufacturing chambers generate extreme conditions: aggressive fluorine- or chlorine-based plasmas, intense radio-frequency (RF) fields, and rapid thermal cycling. A substandard ring can lead to particle spalling, micro-arcing, and disastrous wafer contamination.
Our quartz insulation rings and focus rings are engineered to resolve these challenges:
| Physical / Thermal Property | Fused Quartz Value | Semiconductor Impact |
|---|---|---|
| Chemical Purity (SiO2) | ≥ 99.995% – 99.999% | Prevents metallic wafer poisoning |
| Density | 2.20 g/cm³ | Compact, non-porous structure |
| Softening Point | 1730 ℃ | Retains structural rigidity |
| Continuous Working Temp | 1150 ℃ – 1200 ℃ | Ideal for thermal diffusion/anneal |
| Thermal Expansion (0-300℃) | 5.5 × 10⁻⁷ / ℃ | Immune to extreme thermal shocks |
| Dielectric Constant (1 MHz) | 3.75 | Optimal RF chamber insulation |
