Architectural Acoustics

Semiconductor facilities present unique acoustic challenges due to nanometer-precision manufacturing processes, contamination control requirements, and dense concentrations of support equipment. Unlike typical industrial buildings, semiconductor fabs require simultaneous control of micro-vibration transmission, airborne noise containment, and compatibility with stringent cleanroom protocols. Our designs address these specialized requirements while navigating the complex constraints of semiconductor manufacturing processes.

We select materials and design details specifically engineered for cleanroom environments, including non-shedding, non-outgassing acoustic treatments, cleanable surfaces, and compatible mounting systems. Our approach integrates acoustic elements with cleanroom architecture to maintain required cleanliness classifications while providing effective noise control. We work within ISO standards and specific fab requirements to ensure all acoustic treatments support rather than compromise the controlled environment.

The most critical considerations vary by process area, but typically include vibration isolation for precision tools (particularly lithography and metrology), background noise control for communication and comfort, and isolation from low-frequency vibration sources like pumps and chillers. We develop comprehensive criteria specific to each area's equipment sensitivity, establishing appropriate vibration criteria (VC) curves and noise criteria (NC) ratings based on tool specifications and process requirements.

Yes, though retrofitting operational semiconductor facilities requires specialized approaches that minimize production impact and contamination risk. We develop phased implementation strategies that coordinate with scheduled maintenance periods, utilize cleanroom-compatible installation methods, and incorporate pre-fabricated elements to minimize in-situ work. Our experience with critical manufacturing environments allows us to implement effective acoustic improvements while respecting the operational constraints of 24/7 semiconductor production.

We integrate acoustic considerations into the multidisciplinary design process, collaborating closely with MEP engineers to address potential conflicts between acoustic requirements and the extensive mechanical, electrical, and process systems typical of semiconductor facilities. Our approach includes coordinated penetration detailing, optimized routing of noise-producing systems, strategic equipment placement, and compatible isolation methods. This collaborative process ensures that acoustic solutions function effectively within the densely packed infrastructure of modern semiconductor facilities.
