TMC's Quiet Island® supports the "Resolution Revolution"

Semiconductor manufacturing factories (fabs), Nanotechnology Centers and other high-end precision manufacturing and research facilities often incorporate cleanrooms with a system of raised false floors to accommodate complex facilities requirements (plumbing, electrical cables, gas piping, etc.) and to maintain strict cleanliness standards. Such floors present a challenge to the installation of vibration-sensitive production, inspection, and metrology equipment. The raised floors cannot provide the necessary quiet vibration environment for such tools. TMC's Quiet Island is an innovative solution that replaces a section of the raised floor area with a "Quiet Island" to support the equipment from the sub-floor below.

Custom Optical Table Design and Installation

The new Research Center MAIN of TU Chemnitz in Germany recently added a cleanroom to their Optics/Plasmonics laboratory. The lab required a large optical table surface installed in the cleanroom’s raised floor environment, a somewhat unusual setup.

Quantum Optics and Quantum Computing

Quantum Optics and Computing are very hot topics these days with the potential to radically change the way computers work and to enhance their performance to heights once thought impossible. Quantum Optics is the study of how individual quanta of light, known as photons, interact with matter, such as atoms and molecules.

What are the advantages of using Quiet Islands in place of designing a ‘Quiet’ building?

Instead of trying to build quieter buildings, a more cost effective and successful approach for achieving the stringent requirements of vibration sensitive tools is to employ point-of-use active vibration control with serial piezoelectric technology, particularly to mitigate challenging low frequency (less than 5 Hz) vibration.

Choosing a raised platform for semiconductor facilities

Most semiconductor facilities have raised floors to handle the cleanliness requirements in the fab. Raised floors are typically not used to support environmentally sensitive processing equipment commonly used in chip manufacturing. Instead, these tools are often installed on raised pedestals like a Quiet Island.

For buildings with no central compressed air system, why it is better to run a TMC air table on a silent compressor instead of a bottle of gas?

It is a more “economically favorable” strategy to use a “compressor style air source” from the beginning than facing potential issues with running the table on gas cylinders. A lab compressor will pay for itself over time by reduced cylinder usage. And, advances in compressor technology have resulted in very quiet compressors that do not compromise the performance of the vibration isolation table.

What's the difference between Vibration Damping and Vibration Isolation?

We often get questions about the difference between vibration damping and vibration isolation. Sometimes people use these terms interchangeably, but they are different. In this video TMC’s Sales and Applications Engineer, Jake Porrazzo, uses our CleanBench™ to demonstrate the difference between damping and isolation.

Are Quiet Islands a “Greener” approach to advanced research facilities architecture?

The traditional method to create a quieter building is to use more steel and concrete. And, ultimately, this approach becomes impractical as a building cannot provide a vibration environment quieter than the ground beneath the building. We discuss why Quiet Islands are better, and better for the environment.

What key features should I look for in a vibration isolation joined optical table?

Not all joined optical tables are created equal. Pay particular attention to the way tables are joined. Larger and more complex projects will put more stress on the joints. You want to ensure that your joined tables will give you the stiffness, flatness and damping that your project requires.

Understanding and Measuring Noise Sources in Vibration Isolation Systems

This post briefly introduces the key concepts in noise measurement, and how to interpret the results. Measuring vibration can be tricky, especially for random sources of vibration. Improper measurement can lead to incorrect or ambiguous floor vibration requirements for commercial tools, misleading or inaccurate site surveys, and ultimately incorrect conclusions about system susceptibility and performance.

Vibrations Podcast - Case Study of Cancer Research Facility

Three universities planned to construct a state-of-the art cancer research facility housing high end inspection tools such as TEMs and SEMs on a donated piece of land at a river bank in a busy metropolitan setting surrounded by highways, bridges, light rail traffic, and long-term construction staging and activities. This podcast discusses the vibration challenges that needed to be overcome.

Vibrations Podcast Part 2 - Case Study of Cancer Research Facility

In Part 2 we discuss how noise and vibration activities often worsen once a facility is built. Vibration levels within a building have been shown to increase with time as it is occupied by people and equipment. This can be even worse in urban environments where outside development of train lines, roads and building construction often makes vibration worse with time.
