Features

Open Ion Source Analyzer

The open ion source analyzer incorporates twin filaments, where the second “back-up” filament enables continued operation in the event of a filament failure. The user serviceable analyzer design allows the ion source to be easily removed and dismantled for cleaning. The standard system includes a double-filter analyzer for increased sensitivity of higher mass species, contamination resistance and enhanced long term stability

System Options

Systems can be equipped with a heater jacket and pneumatic isolation valve. A 3-way pneumatic valve for manual control of isolation inlet valve is standard and optional pressure switch assemblies can be chosen to detect within milliseconds when a valve has opened or closed on the tool. This provides Vision 2000-B systems with the flexibility to fully satisfy the application requirements of any vacuum baseline RGA process.

Process Eye™ Professional Control Platform

The Vision 2000-B analyzer uses Process Eye Professional, a highly flexible, modular application operating under 32bit or 64bit Windows XP, Vista, Server 2008 or Windows 7. Designed with a “client/server” structure, Process Eye Professional incorporates TCP/IP protocol for full network compatibility.

Process Eye Professional uses recipes to specify the way in which the instrument scans, displays data, and responds to the data acquired. Recipes are user configurable using the “Recipe Wizard” and are ideal for monitoring the various phases of repetitive recipes.

Recipes can be linked together to address different monitoring conditions or to facilitate automatic calibration (using pre-defined calibration recipes). The single button push (or external signal) initiation of a Process Eye Professional recipe eliminates the need for highly skilled, full time operators. The flexibility of Process Eye Professional allows recipes to be configured that will:

  • Define data acquisition and data display parameters
  • Display data in simultaneous “bar chart” and “data trend” formats, allowing the comprehensive and clear investigation of significant trend events
  • Incorporate custom warnings and alarms, triggered or terminated when data highlights that process conditions have deviated from normal conditions or when specific events occur (e.g. valves opening/closing)
  • Monitor and display other parameters as trends, in relevant units (temperature, gas flow rate, power, pressure, etc.) which are linked into the Vision 2000-B analyzer through its flexible analog and digital I/O

In addition, Process Eye Professional provides “live history” for quick on-line review of data trend events. Recently captured bar chart spectra are stored in a data buffer and can be reviewed by moving a cursor over the associated trend plot.

TOOLweb® RGA

Using TOOLweb RGA sensor integration option for process tools, the Vision 2000-B can be used as a transfer, buffer or loader chamber sensor in a completely automated process environment. TOOLweb RGA maintains a constant monitor of tool activities with all sensor data being framed by wafer logistics before alarm models are applied. Full alarm and data reporting to the FAB host and FDC are available so real time monitoring of chamber conditions and flagging of any process excursions from ideal conditions is possible.

Applications

The Vision 2000-B is an application specific instrument designed to monitor vacuum pumpdown, baseline, and leakback conditions on semiconductor and thin film process tools, and to alert of conditions that can negatively impact product yield. In addition, the Vision 2000-B provides the information required to optimize vacuum quality with:

  • Residual gas monitoring, including air and water
  • Contaminant monitoring, including Hydrocarbons

Example Data

Data from a Vision 2000-B™ TOOLweb® RGA transfer module. The precise timing of slit valve pressure switch sensors compared to using SVIDS from the tool allows accurate diagnosis of which slit valve is causing an air leak on actuation.
