STACIS® is the world's most advanced active vibration
cancellation system. Employing advanced inertial
vibration sensors and state-of-the-art piezoelectric actuators, STACIS® 2100
cancels vibration in real time by sensing floor vibration, then expanding
and contracting piezoelectric actuators to filter out floor motion.
Isolation starts at 0.6 Hz and the active bandwidth is 250 Hz.
Primarily designed to isolate precision microlithography,
metrology, and inspection equipment in
advanced semiconductor factories, STACIS® is now
the industry standard solution for the
most sensitive instruments in noisy environments.
Hundreds of times stiffer than air isolators,
STACIS® suffers from none of the limitations of
air systems. There is no "soft" suspension
and, unlike active air systems, STACIS® can
be "stacked" (placed beneath tool with an internal active
air isolation system). |

The Nikon FX-21S LCD Stepper incorporates
an advanced version of TMC's STACIS® for the ultimate
in vibration control.The rigid mounts yield faster settling times
in response to motion, resulting in higher throughput.

In addition
to facilitating optimal tool performance and resolution in noisy
fabs, STACIS® is guaranteed to meet the floor vibration specifications
of wafer inspection, metrology and microlithography
tools.*
With many hundreds of successful installations
worldwide, STACIS® is the ideal vibration isolation
system for the most vibration-sensitive instruments.
