Demystifying Semiconductor Cleanroom Design: A Primer

Posted: May 17th, 2024

Given the sensitivity of the semiconductor manufacturing process, we believe it’s important to show a certain level of understanding to give our clients in the semiconductor industry peace of mind as we support them in their cleanroom projects.

As cleanroom panel manufacturers, we understand the need for precision is paramount in the semiconductor manufacturing process. Even the tiniest particle can disrupt the delicate processes involved in creating microchips and other electronic components. That’s why cleanroom design is a critical aspect of semiconductor fabrication facilities. Our role is to ensure these controlled environments are meticulously crafted with the right cleanroom components to minimise contaminants and maintain the pristine conditions necessary for producing high-quality semiconductor devices. In this blog, we’ll delve into some of the basics of semiconductor cleanroom design that we consider when making products to support your cleanroom projects.


Understanding Cleanroom Classifications

Understanding how Cleanrooms are classified (on the number and size of particles permitted per cubic meter of air), the various classes (1-9) and the international standards that define them, (ISO 14644 being the most widely used) allows us to ensure that we offer products capable of meeting the most stringent requirements.


Key Components of Cleanroom Design

1. Air Filtration Systems

Knowledge of cleanroom air filtration systems (High-efficiency particulate air filters and ultra-low penetration air filters) and their use (remove particles from the air) means that we’re able to design cleanroom components that help to facilitate this filtration process.

2. HVAC (Heating, Ventilation, and Air Conditioning) Systems

The HVAC system plays a crucial role in regulating temperature, humidity, and airflow within the cleanroom. Precise control of these parameters is essential for maintaining the cleanliness and stability of the environment. HVAC systems in semiconductor cleanrooms are designed to provide consistent airflow patterns and minimize the introduction of contaminants from outside sources.

3. Cleanroom Construction Materials

As part of our semiconductor offering, our products are designed to minimize particle generation and facilitate easy cleaning. Non-porous surfaces such as stainless steel, epoxy resin, and smooth vinyl flooring are commonly employed to prevent the accumulation of particles and facilitate thorough cleaning procedures. Gilcrest offers a range of non-porous finishes, e.g. WFS, PET, and Stainless Steel.


4. Environmental Monitoring and Control

Continuous monitoring of environmental conditions is essential for ensuring the effectiveness of cleanroom operations. Automated monitoring systems track parameters such as particle concentration, temperature, humidity, and air pressure in real-time. This data allows cleanroom operators to detect deviations from the desired conditions and take corrective actions promptly.


Challenges in Cleanroom Design

Controlling contamination from personnel, equipment, and materials requires stringent protocols and meticulous attention to detail. Additionally, maintaining cleanroom integrity in the face of external factors such as building vibrations, electromagnetic interference, and fluctuating utility supplies can be demanding.


Future Trends in Cleanroom Technology

As semiconductor manufacturing processes continue to evolve, cleanroom technology is also advancing to meet the industry’s changing needs. Innovations such as advanced filtration techniques, modular cleanroom designs, and robotic cleaning systems are being explored to enhance cleanliness, efficiency, and flexibility in cleanroom operations.



Semiconductor cleanroom design is a complex yet essential aspect of modern electronics manufacturing. By meticulously controlling environmental conditions and minimizing contamination, cleanrooms enable the precise fabrication of semiconductor devices that power our increasingly interconnected world. As technology continues to advance, so too will the innovations in cleanroom design, ensuring the continued progress of the semiconductor industry.

In conclusion, here at Gilcrest we have the knowledge and the solutions to support our semiconductor clients in any cleanroom projects they undertake.
