Sealing Products in Semiconductor
Semiconductor O Rings
Fully moulded Imperial and Metric O Rings. Manufactured to any size, ranging from 0.030″ to 96″ (0.8mm to 2.4m) internal diameter and 0.030″ to 0.470 (0.8mm to 12mm) cross section. Custom non-standard sizes are also available, which in turn makes them suitable for virtually any application. For more information on our range of O Rings, click here. For specific compounds, see FFKM O Rings, FKM/FPM O Rings, NBR O Rings.
Centering Rings
KF – ISO – NW Flange Fittings (Centering Rings) are used to centre and seal two flanges, in standard NW, KF and ISO sizes. They provide reliable vacuum seals within Semiconductor environments. Our range includes aluminium and stainless-steel centering rings that can be combined with O Ring materials frequently used in semiconductor wafer processing systems.
Slit Valve Doors
Slit Valve Doors (SVDs) are a core component of various semiconductor process tools. They create a barrier between hostile process environments and the more mild areas of the equipment. Demands for ultra-purity and plasma resistance have resulted in the development of specific compounds for the Semiconductor industry. These materials offer supreme performance in sealing those applications. We offer a range of materials and profiles that maximise sealing integrity and life expectancy for bonded and non-bonded slit valve doors and MONOVAT® gates. These are available in many designs and sizes for 150mm, 200mm, 300mm and 450mm process equipment.
End Effector Pads / Wafer Handling Components
Wafer handling components using advanced dissipative elastomers to reduce electrostatic discharge damage. Our range of Dissipative End Effector Pads are specifically designed for use in Semiconductor manufacturing applications. These compounds are free from any metal components (nor metallic based fillers) and other incompatible and undesirable elements that can cause contamination or change in device characteristics. Semiconductor wafers and processes contribute to forming charge imbalances. Electrostatic discharge (ESD) is the main element in equipment failure. Particularly in smaller feature sizes with greater potential for ESD to cause immediate catastrophic failure or partially damaged devices. Our range of materials offers both, low and high coefficients of friction to allow tailoring of wafer retention force. Custom designs of end effector pads are also available.
Lip Seals
Lip seals provide sealing of wider gaps that require large amounts of deflection where limited contact force is available. For more information, see our Lip Seals page.
Micro Seals
Micro Seals are micro sizes rubber components that demand the highest degree of precision and quality to tackle the industry’s most critical applications, including those of Semiconductor. Our range is engineered and customised for your micro component requirements: designed and developed to thoroughly optimize your device or application. Micro Seal elastomer materials are certified compliant with FDA, USP Class VI, 3A 18-03, WRAS, and EC1935-2004. High-temperature capability up to +327°C and low-temperature capability down to -60°C. Virtually universal chemical resistance (FFKM).
