Advanced Filtration Technologies in MAU Design

Modern semiconductor MAU systems incorporate multiple filtration stages to achieve the ultra-clean air quality required for nanometer-scale manufacturing processes. The filtration hierarchy typically begins with pre-filters that remove larger particles and protect downstream components from premature loading. These initial stages utilize pleated filters with efficiency ratings appropriate for the local environmental conditions and outdoor air quality.

The secondary filtration stage employs high-efficiency particulate air (HEPA) filters that capture particles down to 0.3 microns with 99.97% efficiency. However, semiconductor applications often require even higher performance, leading to the adoption of ultra-low penetration air (ULPA) filters that achieve 99.999% efficiency for particles as small as 0.12 microns. These advanced filters undergo rigorous testing and certification processes to ensure they meet stringent cleanroom standards.

HEPA filter systems represent the cornerstone of semiconductor air purification, requiring careful selection, installation, and maintenance protocols. The filter housing design must minimize bypass leakage while providing adequate access for replacement and testing procedures. Additionally, molecular filtration technologies address gaseous contaminants that could affect semiconductor processing, including airborne molecular contamination (AMC) that traditional particulate filters cannot capture.

Temperature and Humidity Control Strategies
