  1. Diffusion Furnace Controller Design Team 14 Joe Grady James Crow Hongyu Chen Prakalp Sudhakar Victor Villagomez Client/Faculty Advisor: Dr. Gary Tuttle

  2. Project Goals The objective of the senior design project is to design a new set of temperature controllers to use on a set of diffusion furnaces located at the Microelectronics Research Center. The project goals include: Updating analog controlled furnace to a digitally controlled furnace. Implementation of a new digital temperature controller integrated into the current microelectronics oven Providing a computer interface so that temperature of the furnaces can be controlled and monitored remotely.

  3. What is due? • Prototype testing of the hardware – Oct 14 • Revised circuit testing of hardware – Oct 21 • Layout of circuit completed – Oct 28 • Implementation of controller, circuit, oven and software – Nov 14

  4. System Overview

  5. Circuit schematic is done and properly interfaces in theory. Get a bare minimum of 270mA to the SCR gates

  6. Software • Implementation Done • Website login system • Website database • Website basic GUI interface • Testing • Black box testing

  7. To be done Software • Get an USB – RS232 (Serial) Adaptor • Write low level interface in Mac’s Xcode • Write the interface between the webpage and the controller software Testing/Evaluation: • Test RS232 com in Mac • Test the webserver

  8. Two levels of success criteria in this project: Critical level – SCR Gate current must be comfortably above 270mA @ 2V Dream level – Critical level reached plus software integration Assessment of Overall Completion: fully successful, mostly, partially, or unsuccessful
