Octiv Suite 2.0

The Octiv Suite 2.0 VI probe is the most advanced RF sensor on the market for in-line power and impedance measurement, with unrivaled accuracy and functionality. It is a non-intrusive, in-line sensor used to monitor all the parameters of RF power, break them down to their individual components and reconstruct the waveform of multiple fundamental frequencies simultaneously. This cutting edge system can also measure plasma parameters such as ion flux by using the RF electrode as a sensor. The Octiv Suite is truly in a class of its own when it comes to power delivery into a plasma reactor. It can be used as a stand-alone instrument with our state-of-the-art software or integrated directly with any software platform using one of our advanced communication protocols.

Key Features
Choice of 5 frequencies on a single sensor, measures multiple frequencies simultaneously.
Unrivalled accuracy into 50 Ω and non-50 Ω impedances through our advanced calibration methodology.
Sensor run-to-run repeatability (<0.1%) enables a true gauge of plasma process drift.
Single and multi-frequency voltage and current waveform display.
Ion flux monitoring capability provides a direct correlation with etch and deposition rates.
Fundamental-to-harmonic phase output, a key parameter for endpoint detection.
All available for pulsed-RF, in both time-resolved mode (1 microsecond resolution) and in pulse-trend mode.
Key Benefits
Equivalent performance to network analyser and oscilloscope combined, in-line at high power.
Advanced endpoint capabilities using plasma impedance and harmonic spectrum analysis.
Detect etch endpoints (<1% open area) with higher sensitivity than multivariate OES endpoint detectors.
Live output of ion flux, plasma density and electron temperature is possible (see Plato Probe).
Significant cost benefits through the enablement of fault detection and early intervention.
USB, Ethernet, EtherCAT and Serial communication protocols with easy-to-use APIs for integrations.
These Advanced applications can be achieved rapidly using the “Impedans Expert” software package and with assistance from Impedans applications team.

Compatible with all QC connectors. Capable of being changed in the field, allowing the unit to be moved between chambers with different connectors if desired.
