Silicon Valley Group: 200-APS

The 200-APS (Advanced Processing System) is a next generation photo processing system for 200mm wafers. The machine is highly scalable by adding additional banks of modules. Wafer transport between the cassettes, the processing modules, and the stepper were handled by three separate robots.

  • Helped rebuild a team of software engineers to complete development of the 200-APS after an unusual exodus of several key software engineers.
  • Provided software design and development on many aspects of this complex machine from the user interface, to mid and low level engineering.
  • Software was based on a Smalltalk factory automation software framework from Texas Instruments called ControlWorks, and C for low level computer boards.
