ASTRA Furnace Controller

Industrial control panel display showing process parameters, alarms, and controls for a manufacturing system, including buttons for start, stop, auto mode, hold, jump to, and alarm management.

The ASTRA Control System provides integrated control of all diffusion and LPCVD furnace system parameters. ASTRA is Ethernet-based using distributed control via a high-powered, tube-level microcomputer and intuitive, process-logical software.

 All ASTRA operations are accomplished through graphical and animated, touch screen access. Comprehensive data acquisition, logging and graphing provide real-time assessments for optimum process management

ASTRA Benefits

  • Precise control of temperature, gas and fluid flow, vacuum and loading parameters for optimum process performance and repeatability.

  • Intuitive programming and operation through graphical touch screen access for easy training and operation. 

  • Tube-level microcomputer for high speed and masterful data management, which results in optimized yields and process tracking. 

  • Distributed control with full safety interlocks for gas flow, vacuum, temperature and loading, which provide safe, reliable operation. 

  • Optimized temperature control with divisible cascading and auto profiling to setup and maintain optimum temperature parameters.

  • User permissions protocols assure only qualified personnel can access programming, recipes and parameters.

  • Comprehensive alerts, alarms, redirects and monitors
    for all parameters. Provides instant responses, reporting and recording of anything that affects process performance or safety.

  • Full maintenance accessibility with integral trouble-
    shooting and calibrations. Provides data for maintenance with no additional maintenance computer required.

  • Advanced LPCVD control and monitoring functions for
    sustained process repeatability.

  • On-screen keyboard for easy data entry.

  • Lot tracking/run history for multiple lots per run. Allows recipe tracking of wafers and wafer lots.

  • Retrofitable to most any furnace brand or model. Modernizes all control attributes at low cost.

  • Optional ASTRA Host System. Provides centralized factory recipe management, downloading, data acquisition and logging for up to 99 tube-levels.
