Managing Odors and Corrosion in Semiconductor Manufacturing
Meeting strict standards for component integrity is critical in semiconductor manufacturing. The development of semiconductor products and components often requires the use of chemicals like acids, solvents, and ammonia, which often results in strong, unpleasant odors that can disrupt the workplace and pose significant risks. These odors are not just an inconvenience; they can signal the presence of airborne contaminants that threaten, not only the quality of semiconductor products, but the health and safety of people working in the area.
Untreated Chemical Odors Put People and Products at Risk
Prolonged exposure to chemical odors, such as those from ammonia and solvents, can lead to potentially serious health risks, including respiratory issues, headaches, and long-term health problems like chronic respiratory conditions. In the short-term, uncontrolled odors can create an uncomfortable and unsafe work environment, which not only impacts employee morale but can also reduce productivity and increase the risk of accidents.
The odors left during chemical processes are often an indicator of airborne contaminants. In semiconductor manufacturing, even trace amounts of contaminants can lead to product defects. This compromises the reliability and performance of semiconductor devices, leading to decreased yield and higher production costs.
Corrosive Gases: A Silent Threat to Electronics
In addition to odors, semiconductor manufacturing environments are often affected by corrosive gases such as sulfur dioxide (SO2), hydrogen sulfide (H2S), ammonia, and nitrogen oxides (NOx). These gases can cause significant damage to electronic components through oxidation and corrosion. Ensuing problems include:
- Increased Electrical Resistance – Corrosive gases can lead to oxidation on metal surfaces, increasing electrical resistance and causing poor connectivity. This can result in signal loss and reduced product performance.
- Short Circuits – Corrosion can create unintended conductive paths, resulting in short circuits that can damage sensitive semiconductor components. This can ultimately lead to the need for costly repairs or replacements.
- Component Failure – Over time, the integrity of electronic components is compromised due to corrosion, leading to premature failure of these components and potentially causing entire systems to malfunction.
PureAir Filtration’s Comprehensive Odor Control Solution
Ordinary air filtration solutions are not simply not sufficient for the sensitive semiconductor manufacturing industry. That is why PureAir Filtration offers customized, high-quality air purification systems specifically designed to address these challenges. Here’s how PureAir Filtration’s products can help safeguard your semiconductor manufacturing environment:
Air Purification Systems
Packaged Filter Unit (PFU)
The PFU is a versatile air purification system designed for environments where space is limited or flexibility is required. The modular design of the PFU allows for easy installation in a variety of configurations, as well as easy maintenance. The PFU can be equipped with various types of adsorbent media, including Ammoniasorb® and Sulphasorb 2™, to target specific contaminants. This makes the PFU approach an ideal solution for semiconductor manufacturing facilities where both odor control and corrosion prevention are necessary.
Side Access Housing (SAH)
The SAH system is designed for applications where frequent media changes are required. This design provides easy access to the filters, allowing for quick and efficient maintenance. The SAH can be configured with multiple stages of filtration, including particulate filters and gas-phase media like Sulphasorb 2™ and Ammoniasorb®, to ensure comprehensive air purification. This ensures that ambient air remains free of harmful contaminants and corrosive gases.
Cylinder Canisters and PP Modules
For facilities with specific filtration needs, PureAir offers cylinder canisters and PP modules that can be filled with the appropriate adsorbent media. These systems are highly adaptable and can be tailored to target specific gases or odors present in your facility. The canisters and modules are designed for ease of installation and replacement, ensuring that your air filtration system remains effective and efficient over time.
Adsorbent Media
Ammoniasorb® is a specialized adsorbent media designed for the effective removal of ammonia gas. Ammonia is a common byproduct in semiconductor manufacturing, and its presence can lead to odors and contamination. Ammoniasorb® works by trapping and neutralizing ammonia molecules, ensuring that they do not interfere with sensitive manufacturing processes.
Sulphasorb 2™ is engineered to remove harmful gases such as sulfur dioxide (SO2) and hydrogen sulfide (H2S). These gases are highly corrosive and can cause significant damage to electronic components. Sulphasorb 2™ contains a blend of activated carbon and proprietary chemicals that react with and neutralize these gases, providing long-lasting protection against corrosion.
