Book excerpt: The California Energy Commission sponsored this roadmap to guide energy efficiency research and deployment for high performance cleanrooms and laboratories. Industries and institutions utilizing these building types (termed high-tech buildings) have played an important part in the vitality of the California economy. This roadmap's key objective to present a multi-year agenda to prioritize and coordinate research efforts. It also addresses delivery mechanisms to get the research products into the market. Because of the importance to the California economy, it is appropriate and important for California to take the lead in assessing the energy efficiency research needs, opportunities, and priorities for this market. In addition to the importance to California's economy, energy demand for this market segment is large and growing (estimated at 9400 GWH for 1996, Mills et al. 1996). With their 24hr. continuous operation, high tech facilities are a major contributor to the peak electrical demand. Laboratories and cleanrooms constitute the high tech building market, and although each building type has its unique features, they are similar in that they are extremely energy intensive, involve special environmental considerations, have very high ventilation requirements, and are subject to regulations--primarily safety driven--that tend to have adverse energy implications. High-tech buildings have largely been overlooked in past energy efficiency research. Many industries and institutions utilize laboratories and cleanrooms. As illustrated, there are many industries operating cleanrooms in California. These include semiconductor manufacturing, semiconductor suppliers, pharmaceutical, biotechnology, disk drive manufacturing, flat panel displays, automotive, aerospace, food, hospitals, medical devices, universities, and federal research facilities.

This book was released on with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the fast-evolving world of electronics manufacturing, the role of clean rooms cannot be overstated. These controlled environments are essential for producing high-quality, reliable electronic components and devices, which are integral to nearly every aspect of modern life—from consumer electronics to medical devices, automotive systems, and aerospace technology. The primary function of a clean room is to minimize the introduction, generation, and retention of particles within the space. This is crucial because even microscopic contaminants can significantly impact the performance, reliability, and longevity of electronic components. Clean rooms are designed to maintain extremely low levels of particulate matter, achieved through stringent control over air filtration, pressure, temperature, and humidity. Importance of Clean Rooms in Electronics Manufacturing Contamination Control: Electronic components, particularly semiconductors, are highly sensitive to dust, bacteria, and other airborne particles. Clean rooms ensure that these contaminants are kept at bay, protecting the integrity of the manufacturing process. Quality Assurance: The use of clean rooms helps in maintaining the high standards required in electronics manufacturing. This translates to fewer defects, higher yields, and better performance of the final products. Compliance with Standards: Many sectors, especially those involving medical devices and aerospace technology, have stringent regulatory requirements. Clean rooms help manufacturers comply with these standards, ensuring that their products are safe and reliable. Innovation and Precision: Advanced electronics manufacturing often involves nanotechnology and microelectronics, where precision is paramount. Clean rooms provide the controlled environment necessary for such high-precision work. Key Elements of a Clean Room Air Filtration Systems: High-Efficiency Particulate Air (HEPA) filters and Ultra-Low Penetration Air (ULPA) filters are used to remove particles from the air, ensuring that the environment remains contaminant-free. Controlled Environment: Parameters such as temperature, humidity, and pressure are meticulously controlled to prevent any adverse effects on the manufacturing process. Clean Room Classifications: Clean rooms are classified based on the number and size of particles permitted per volume of air. The most common classification standards are those of the International Organization for Standardization (ISO). Personnel and Equipment Protocols: Strict protocols for personnel, including the use of special clothing and hygiene practices, are essential. Similarly, equipment used in clean rooms is designed to minimize the generation of particles. Challenges and Considerations Cost: Establishing and maintaining clean rooms is expensive. This includes the cost of sophisticated filtration systems, environmental controls, and regular maintenance. Training: Personnel working in clean rooms require extensive training to understand and adhere to strict protocols. Technology Upgrades: As technology advances, clean rooms must be regularly updated to meet new standards and accommodate new manufacturing processes. Conclusion Clean rooms are indispensable in the realm of electronics manufacturing. They play a critical role in ensuring that the components and devices produced meet the highest standards of quality and reliability. As the industry continues to innovate and evolve, the importance of clean rooms will only grow, making them a cornerstone of modern manufacturing processes.

Book excerpt: A high-performance cleanroom should provide efficient energy performance in addition to effective contamination control. Energy-efficient designs can yield capital and operational cost savings, and can be part of a strategy to improve productivity in the cleanroom industry. Based upon in-situ measurement data from ISO Class 5 clean rooms, this article discusses key factors affecting cleanroom air system performance and benefits of efficient airflow design in clean rooms. Cleanroom HVAC systems used in the semiconductor, pharmaceutical, and healthcare industries are very energy intensive, requiring large volumes of cleaned air to remove or dilute contaminants for satisfactory operations. There is a tendency, however, to design excessive airflow rates into cleanroom HVAC systems, due to factors such as design conservatism, lack of thorough understanding of airflow requirements, concerns about cleanliness reliability, and potential design and operational liabilities. Energy use of cleanroom environmental systems varies with system type and design, cleanroom functions, and the control of critical parameters such as temperature and humidity. In particular, cleanroom cleanliness requirements specified by cleanliness class have an impact on overall energy use. A previous study covering Europe and the US reveals annual cleanroom electricity usage for cooling and fan energy varies significantly depending on cleanliness class, and may account for up to three-quarters of total annual operating costs. A study on a semiconductor cleanroom in Japan found air delivery systems account for more than 30% of total power consumption. It is evident that the main factors dictating cleanroom operation energy include airflow rates and HVAC system efficiency. Improving energy efficiency in clean rooms may potentially contribute to significant savings in the initial costs of the facilities as well as operation and maintenance costs. For example, energy consumption by a typical chip manufacturer can be cut 40% or more, and the associated greenhouse emissions even more. Cleanroom HVAC systems provide huge opportunities for energy savings in the semiconductor industry. In addition to direct cost reductions in cleanroom investment and operation, energy-efficient designs can reduce maintenance costs, increase power reliability, improve time-to-market in cleanroom production, and improve environmental quality. Companies that use energy efficiency to lower costs and increase productivity can gain a competitive advantage and achieve a higher return on investment. In addition, energy-efficient cleanroom systems conserve energy and natural resources, heightening the company's reputation as an environmentally conscious leader in the community and the industry. A significant portion of energy use in cleanroom environmental systems is associated with recirculating air systems. We will review and analyze design factors and operational performance of airflow systems in ISO Class 5 clean rooms. We will also discuss benefits of efficient cleanroom airflow designs in conjunction with effective cleanroom contamination control. We will consider the following common recirculating air system designs: fan-tower (FT) with pressurized-plenum; distributed air handler unit (AHU); and fan-filter unit (FFU).
