Semiconductor Manufacturing Infrastructure Solutions

Semiconductor fabrication plants operate under stringent cleanroom standards, these facilities require high-purity fluid handling and precise climate control to ensure maximum yield and prevent contamination. To maintain this level of precision, Proco Products, Inc. provides high-performance expansion joints and flexible connectors engineered to handle the corrosive chemicals and high-purity water systems essential to semiconductor production.

Protecting Ultra-Clean Environments

The manufacturing of semiconductors involves aggressive chemical processes and ultra-pure water (UPW) loops that are sensitive to even microscopic levels of contamination. Proco expansion joints are strategically utilized to:

• Isolate Micro-Vibration: Protect sensitive lithography and etching equipment by dampening mechanical vibration from high-capacity pumps and chillers.
• Resist Chemical Attack: Manage highly corrosive acids and solvents used in wafer cleaning and chemical mechanical planarization (CMP).
• Relieve Mechanical Stress: Accommodate thermal expansion and contraction in complex piping runs caused by temperature fluctuations in process cooling.
• Ensure Leak-Free Integrity: Reduce the risk of pipe ruptures that could lead to water damage, contamination, and catastrophic operational downtime.

Semiconductor Applications Supported by Proco Products

Proco’s solutions are integrated into the critical infrastructure that supports the specialized needs of semiconductor fabrication plants

• Ultra-Pure Water (UPW) Systems: PTFE joints ensure that high-purity water remains free of metallic contaminants or rubber particulates.
• Chemical Delivery & Waste: PTFE-lined rubber joints handle the transport of aggressive chemicals and slurries across the facility.
• Cleanroom HVAC & Exhaust: Rubber expansion joints in ducting systems cope with thermal movement and misalignment while isolating fan vibration.
• Process Cooling Water (PCW): Series 231 and 240 joints manage chilled water loops that regulate the temperature of production tools.
• Emergency Power: Braided metal connectors manage thermal growth in generator exhaust systems that can exceed 1,000°F.

Proco Semiconductor Expansion Joint Selection

Molded PTFE and Rubber expansion joints are easy to fit and are resistant to corrosion, temperature, and chemicals. They require low maintenance and can reduce turbulence and sediment build-up.

Proco rubber expansion joints and molded PTFE joints are used in the semiconductor industry for a number of functions:

• They absorb vibrations and noise from pumps, engines, and compressors.
• In semiconductor processing, molded expansion joints made from low outgassing silicone materials can be used to help prevent the process of releasing gas that was trapped, frozen, dissolved, or absorbed into a material.

Selecting the right joint for semiconductor applications requires balancing material compatibility with the need for high-purity standards.

Braided Metal	Stainless Steel	High-pressure gas delivery and mechanical room backup systems.

 

STAMPED Selection Method for Semiconductor Fabrication Plants

Use the STAMPED method to ensure your joint selection is perfect for the specific requirements of a semiconductor environment:

S – Size: Account for precise pipe I.D., flange drilling, and face-to-face length.

T – Temperature: Use PTFE or braided metal for systems exceeding 250°F.

A – Application: Identify the specific media, such as UPW, glycol, or aggressive acids.

M – Movement: Calculate expected thermal expansion and building shifts.

P – Pressure: Account for operating, test, and surge pressures within the process lines.

E – End Fittings: Specify flange materials to prevent galvanic action or match existing equipment patterns.

D – Delivery: Proco maintains extensive inventory to support rapid fab construction and emergency repairs.
