DVIA-P Series

Active Vibration Isolation System for Semiconductor, Metrology, and Inspection Tools

The DVIA-P series is an active pneumatic vibration isolation system for advanced processing, metrology, and inspection tools with onboard wafer loaders. The isolators use sensitive sensors and powerful pneumatic actuators to counteract vibrations from floors and tools, providing low-frequency isolation and ultra-fast settling time while accounting for the movement of onboard linear stages.

DVIA-P Vibration Transmissibility Performance

Superior Vibration Isolation Performance

Advanced feedback and feedforward vibration control algorithms are embedded in the DVIA-P, delivering 40 – 70% at 2 Hz in six degrees of freedom.

Custom Design Based on Unique Tool Footprint

Using site survey data VEC designs your DVIA-P isolation system based on the unique requirements of your tool.

Sophisticated Feedback & Feedforward Controls​

A) Stage Feedforward

Stage feedforward counteracts movement from motorized stages by producing an equal and opposite force based on advanced information about the stage position.

B) Acceleration Feedback

The acceleration feedback system uses sensors and actuators to detect and minimize vibrations from the floor and motorized linear stages.

C) Position Feedback

Position feedback measures displacement through position sensors, and the digital controller drives actuators to return the isolated base to its original position, improving accuracy.

D) Floor Feedforward

The floor feedforward system filters floor vibrations based on known factors like applied force and ambient vibrations, and tunes feedforward gains to operate actuators.

Ultra-Fast Settling Time & Excellent Position Accuracy

Position sensors constantly measure and maintain the isolation system's position using a digital signal processor, greatly enhancing accuracy. Accelerometers swiftly detect floor or stage vibrations, transmitting signals to actuators for instant vibration cancellation.
