Anti-vibration platform STACIS Quiet Island

Semiconductor manufacturing factories (fabs), Nanotechnology Centers, Nanofabs, and other 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" anchored to the sub-floor below. The Quiet Island consists of a cleanroom compatible platform top combined with an application and site specific support structure. Vibration Cancellation The main support element and core technology unique to the Quiet Island is the STACIS III Active Vibration Cancellation System. This "rigid" style inertial vibration cancellation support system is critical for any vibration sensitive instrument, enabling such tools to operate to their highest standards in an otherwise noisy environment. STACIS III is compatible with automated wafer processing tools, high resolution eBeam imaging tools, ion-beam milling tools, and any tool with internal vibration isolation systems, both passive and active (see our white paper on stacking active on active isolators). In addition, it provides the most vibration isolation across the widest frequency range commercially available. And, the "hard-mount" design is extremely stiff so that there is no stability concern for tall, top-heavy tools.
