Novx Corporation, the leading supplier of ESC/ESD-related monitoring instruments, cleanroom and ESD protective work area monitoring and control solutions, is introducing the next generation process monitoring and control instrument the NanoPulse Series 7000.

The NanoPulse sensor has been developed for ESD/EMI applications requiring a constant dedicated monitoring strategy in highly constrained processing environments. The combination of smart signal processing to identify ESD events from most background noise with the freedom to adapt antenna types and configurations for specific applications makes it a valuable addition to process monitoring. The NanoPulse uses dynamic threshold analysis to determine ambient noise level and form the first part of ESD pulse event discrimination. It also addresses a spectral range of 1MHz to 8GHz, which accommodates ESD event bandwidth as well as most commonly encountered electromagnetic noise frequencies.

The NanoPulse also tracks electromagnetic noise levels separately from ESD event detection and analysis, allowing separate alarm reporting. Alarm reporting levels for both ESD events and EM levels are user programmable. The instrument facilitates direct reporting of monitored parameters from a significant number of tools and may be simultaneously interfaced to the process tool and monitoring system (PEMS) for data storage and report generation. The Series 7000 monitor and its associated workstation and/or process equipment, has the capability to directly perform SPC calculations and direct tool communication in addition to previously available reporting functions.

Another feature of the NanoPulse is antenna independence. Both active and passive antennas in a variety of configurations can be implemented to further tune ESD event detection. In some cases, specialized antennas can be implemented which are direct analogs for very sensitive product and which can correctly represent true product vulnerabilities to radiated energy. In applications with accessibility and space restraints, small form-factor antennas can be installed directly at the monitoring point with sensor processing taking place in the Series 7000 at a more accessible location.

This instrument is capable of communicating with industry standard particle counters and particle detectors in addition to its own ESC/ESD-related monitoring capabilities with the ability to report data using RS-485, ModBus, Ethernet, Wireless Ethernet (802.11a/b/g) protocols. Additional capabilities include detection of field charge (ionization balance monitoring) with automatic or manual decay testing, EMI magnitude and pulse counting, dual-channel ground monitoring and operator voltage or body current detection (patent pending) all with programmable alarm thresholds via a PC interface. Novx has developed this instrument with customer programmable sensitivity and alarm threshold sensing to meet and exceed customer requirements for an extended period of time. The instrument is designed with a modular construction allowing the user to add optional plug-in process enhancements as required. The plug-in modules include digital I/O communication adding direct interface to PEMS, particle count reporting, field sensing with decay testing, EMI detection, operator body voltage or current and ground monitoring. The combination of hardware and software allows the user to monitor, analyze and control processes 24/7 365 days a year.

The introduction of the Series 7000 represents a direct response to strategic customer communication that defines their process requirements for ESC/ESD-related monitoring for today and tomorrow's processes. The digital I/O communication plug-in module provides a proactive function when interfaced to PEMS to receive and report warning or alarm conditions to control the process. This platform will directly reduce process variations, decrease scrap/rework and improve process yields at the specific workstation level. The result will be process yield improvement, an increase in tool availability resulting in an increase in factory capacity. Utilizing the Series 7000 will result in a more accurate way of evaluating operator and tool performance and complements the Novx complete line of ESC/ESD-related instruments and environmental sensors. A single sensor may also be connected to the instrument when interfaced to the PEMS Software, ideal for workstation characterization. In addition, a real-time alphanumeric display (Remote Display) for engineering analysis and continuous monitoring can also be connected to the Series 7000. The Remote Display includes body voltage levels, ground resistance values, field charge (ionization balance) levels, EMI count and peak voltage.
