PEEK ring for semiconductors

At Kriloha Ltd., we understand that in the semiconductor industry, “clean” is a relative term—perfection is the only standard. Our PEEK Rings for Semiconductors represent our engineered answer for “Contamination-Zero-Security” and “Vacuum-Integrity-Stability.” As a premier manufacturer of high-performance polymer solutions, Kriloha has established a “Clean-Room-Focused” fabrication protocol to ensure that every ring meets the stringent requirements of modern fab environments.

The engineering of our semiconductor ring program is founded on Material-Purity and Surface-Roughness ($R_a$) Optimization. By utilizing state-of-the-art 5-axis CNC machining, we eliminate the risk of “parting-line” debris and internal stresses associated with molding. At Kriloha, we verify the outgassing profiles and ionic purity of every batch, resulting in “Failure-Resistant” components that enable higher yields and longer maintenance intervals for your critical process tools.

Manufacturing these advanced polymer components involves strict Dimensional Verification, Plasma-Exposure Testing, and ESD-Calibration. We collaborate directly with your process engineers to develop bespoke configurations—including specialized “vent-grooves” for vacuum applications and proprietary geometries for wafer retention. By choosing Kriloha Ltd., you are investing in a “Future-Proof” manufacturing partnership that prioritizes your yield through superior material science.

Primary Use Cases

Wafer Handling & Carriers: Precision rings used to secure and transport silicon wafers through various processing stages without scratching or contaminating the surface.
Etch & CVD Chambers: High-purity sealing rings and spacers used within vacuum chambers to provide a leak-proof, plasma-resistant mechanical interface.
CMP (Chemical Mechanical Planarization): Wear-resistant retaining rings that provide uniform pressure during the wafer polishing process.
Wet Bench Tools: Corrosion-proof rings for chemical delivery systems handling aggressive acids, bases, and deionized water.
Ion Implantation: Non-magnetic and thermally stable rings used in the high-energy environments of ion beam systems.

Frequently Asked Questions

Why is PEEK preferred over Fluoropolymers (like PTFE) in semiconductor tools?

While PTFE is chemically resistant, it is soft and can “shed” particulates under mechanical load. PEEK provides similar chemical resistance but is much harder and more wear-resistant, leading to significantly lower particulate contamination in the chamber.

Can Kriloha provide ESD-safe PEEK rings for static-sensitive areas?

Absolutely. We offer carbon-reinforced and dissipative PEEK grades that provide controlled electrical conductivity, preventing the buildup of static charges that could cause “Electrostatic Attraction” (ESA) of dust or damage the wafers.

Is PEEK safe for use in Ultra-High Vacuum (UHV) systems?

Yes. PEEK is one of the few polymers recognized for its UHV compatibility. Its extremely low outgassing rate ensures that vacuum levels are reached faster and maintained more consistently without contaminating the process.

How does PEEK handle aggressive etching chemicals like HF (Hydrofluoric Acid)?

PEEK exhibits excellent resistance to a wide range of chemicals used in semiconductor wet processing, including HF, ensuring that the rings do not soften, swell, or degrade during operation.

Are custom layouts available for proprietary tool architectures?

Yes. We specialize in precision CNC technology to achieve sub-millimeter accuracy for any custom diameter, profile, or integrated feature required by your proprietary tool designs.
