Designed for Metrology tools with nanometer-scale measurements.

Nanometer-scale metrology lives at the noise floor of the building itself. A truck on the loading dock. A pump in the subfab. A door closing two bays away. Each event registers as motion under the column — and at sub-nanometer resolution, that motion becomes the measurement. The DVIA-P was engineered to remove that variable. Active pneumatic isolation cancels disturbance in real time, across all six degrees of freedom, before it ever reaches the stage. What the tool measures is the wafer. Not the floor it stands on

Engineered for semiconductor metrology at every node.

The DVIA-P supports the full range of front-end and mask-shop tools that define modern semiconductor manufacturing. Each configuration is engineered to the specific process the tool runs.

CD-SEM

Critical Dimension SEM

Sub-nanometer linewidth measurement.

CD-SEMs measure feature widths at advanced process nodes. Floor vibration broadens edge profiles and degrades repeatability. The DVIA-P delivers vibration-free wafer staging at the precision modern lithography demands.

DR-SEM

Defect Review SEM

Catch every defect. Skip every false call.

Defect review depends on stable beam-to-stage alignment as the SEM scans across the wafer. Imperceptible floor motion produces image artifacts indistinguishable from real defects. The DVIA-P holds the tool steady through full-wafer inspection cycles.

Photomask Repair

Photomask Repair

Repair to the original spec.

Mask repair tools deposit and remove material at the nanometer scale. Tool stability during the repair operation determines whether the mask returns to spec or fails final inspection. The DVIA-P keeps the repair head locked onto its target.

Reticle Inspection

Reticle Inspection System

Every die. Every defect. Zero noise.

Reticle inspection scans every micron of the photomask for defects that could replicate across millions of die. Vibration introduces image noise that masks real flaws. The DVIA-P delivers the mechanical silence reticle inspection demands.

E-Beam Lithography

E-Beam Lithography

Precision patterns. Pristine edges.

Pattern transfer at the nanoscale demands a vibration-free writing field. Floor disturbances translate directly into line- edge roughness and overlay error. The DVIA-P isolates the lithography column at the frequencies that matter most.

In-Line X-Ray

Automated X-Ray Inspection

Sub-micron CT. 24/7 on the production line.

In-line AXI resolves hidden solder joints in BGAs, flip-chips, and power packages through 3D CT reconstruction. At sub-micron detector resolution, any motion between source, sample, and detector during the scan becomes a volumetric artifact. The DVIA-P removes it.

Mask Aligner

Mask Aligner

Mask-to-wafer overlay, held steady.

Mask aligners require sub-micron registration between mask and wafer during exposure. Building vibration corrupts overlay accuracy and reduces yield. The DVIA-P delivers the stable platform exposure tools depend on.

Picometer topography. 24/7 on the fab floor.

In-line 3D AFM delivers picometer-scale topography on the active fab floor — a physical probe against the wafer, 24/7. At a noise floor below 35 pm, any relative motion between tip and sample is the measurement error. The DVIA-P removes it.

Every component. One purpose.

Powerful force, by design.

Pneumatic servo valves counter disturbance in exact proportion to the payload. Pneumatic force scales with the load. From 500 kg metrology tools to 20,000 kg metrology tools, the response matches the tool and with Stage Feed-Forward, settling time collapses on every move.

Ultrafast settling time.

Motorized linear stages must settle to nanometer precision before imaging can begin. The DVIA-P's active control collapses that interval disturbances counter the moment they appear, and the platform returns to setpoint without delay. Less time waiting. More wafers measured.

20,000 kg payload. No compromise.

Semiconductor metrology and inspection equipment can weigh tens of tons. The DVIA-P carries 20,000 kg without sacrificing a single axis. Full active isolation across all six. Maximum payload, uncompromised motion control.

Feedback corrects. Feedforward anticipates.

Feedback senses vibration on the isolated mass and counters it in real time. Feedforward reads the floor and cancels disturbances before they arrive. Together they deliver up to 90% vibration isolation at the low frequencies where semiconductor tools are most sensitive. Two control loops. One outcome.

10 μm Position Accuracy.

10 μm. Held continuously. Position sensors track the platform without pause, and a digital signal processor returns the actuators to setpoint the moment drift appears. Hour after hour. No intervention. A reference engineered to be absolute.

Control, uncompromised.

Nineteen channels in. Ten channels out. Sixteen-bit sampling. Twenty-four-bit drive. The DVIA-P digital controller calculates every source of vibration the instant it appears, then commands the pneumatic actuators in real time. Synchronous. Continuous. The control architecture that defines the series.

The control architecture behind nanometer stability.

DSP Feature Overview

Explore the advanced feedback and feed-forward mechanisms that ensure optimal vibration isolation performance.

A

Stage Feed-Forward

If the isolation system has information about motorized linear stages in advance, the system can produce the force that equal in size to the force from dynamic linear stage motions in the opposite direction. As a result, the external force caused by the motorized linear stage is effectively minimized.

B

Acceleration Feedback

This feedback control system employs sensors and actuators to continuously detect vibrations which disturb the isolated payload, then reacts to minimize vibrations. The acceleration feedback system not only reduces from the floor but also effectively minimizes vibrations from the motorized linear stages.

C

Position Feedback

When the isolated base is disturbed by vibrations, the position feedback measures displacement through position sensors that transmit signals into the digital controller. After receiving the signals from the sensors, the digital controller drives actuators to return its original position, improving the position accuracy.

D

Floor Feed-Forward

The floor feed-forward system filters the floor vibrations in a predefined way. The feed-forward control system is utilized when there are known factors such as a force applied to the isolated base, the data of ambient vibrations and information about equipment that needs to be isolated. Unlike the feedback control system, the feed-forward system analyzes dynamic characteristics of the equipment and tunes the feed-forward gains by the trial and error method to operate the actuators.

Control in Six axes.

The DVIA-P controls all six degrees of freedom independently. Its algorithm decouples each axis, eliminating cross-coupling. Sub-micron translational and sub-microradian angular stability, maintained simultaneously.

FDC Native SECS/GEM.

The DVIA-P streams its full state into the fab's host system over native SEMI standards — HSMS (E37), SECS-II (E5), GEM (E30). As the passive equipment, the platform listens for the major semiconductor FABs. Every second, a single S6F1 trace message carries 30 SVIDs: FLOAT and ACTIVE lamps, three vibration alarms, communication faults, six displacement channels, nine acceleration channels. Internal polling: 500 ms. Trace transmission: 1 s. No middleware. No event chatter. Trace-only by design.

HSMS

TCP/IP transport. The platform listens as passive equipment; Smart-EAP connects as active. Select, Linktest, and Separate handled per E37 state machine. T3, T6, T7, T8 timers enforce the session.

SECS-II

Message format. S1F13/14 establishes communication, S2F23/24 starts the trace, and S6F1 streams the payload in big-endian — every second. W-bit fixed to 0. No host acknowledgment required.

GEM

Equipment model. Online and offline state, alarms, status, and trace data — the platform exposes itself as a standard GEM equipment to Smart-EAP. Monitoring only; FLOAT/ACTIVE control stays on the platform.

30 SVIDs

Per S6F1 message: 7 status and alarm flags, 6 displacement channels (Z1, Z2, Z3, Y1, X2, Y3), and 9 acceleration channels — including Zb, Xb, Yb base. I4 integers, 10 μm and 10 μm/s² resolution.

Monitoring · Alarm · Log

A dedicated Windows monitoring application ships with every DVIA-P. It polls the DVIA-P controller over RS-232 in real time Vibration, Floating status, Position, Communication and latches every alarm in memory until the operator clicks Confirm. The instant something fires, the app jumps from minimized to topmost on the screen. No notification toasts. No chance of being missed. Every state change is timestamped and written to disk.

POLL

Real-time

Periodic Z2CR command over RS-232 at a configurable interval. The 16-bit DO state is read, decoded, and compared cycle-to-cycle. The controller runs at 57600 bps; the controller at 115200 bps with bit-inverted decoding.

LATCH

Alarm history

OR-latched alarm state. Transient events that fire and clear in a single polling cycle still appear in the history bar. The bar holds until the operator clicks Confirm.

TOPMOST

Visual alert

The app stays minimized during normal operation. The instant any alarm fires, the window jumps to topmost. Confirm returns it to minimized — until the next event.

LOG

Persistence

Every state change written to disk with a timestamp. Log rotation keeps the most recent 100 lines hot in log.txt; the previous 400 archive automatically. UTF-8 unicode throughout — no Korean character corruption.
