ECE 5240G Advanced Semiconductor Processing Laboratory | ECE | Virginia Tech


Course Information


Design, layout, fabricate, and characterize microelectronic devices. Analyze test results to verify performance to the predetermined specifications. Participate on a team project in which they will develop processes used to fabricate more advanced devices and/or circuits. Required oral and written reports.

Why take this course?

This course provides the laboratory experience necessary to demonstrate all of the principles of semiconductor wafer design, fabrication, and testing. It is a critical course for preparing graduate students for working in a university research environment and/or for working in the microelectonics industry.

Learning Objectives

  • 1. Design the mask patterns required to fabricate a microelectronic device or circuit.
  • 2. Work in a cleanroom environment using proper safety and cleanroom protocols required to assure integrity of the lab and wafer and safety of the student and coworkers.
  • 3. Demonstrate proficiency in performing processing procedures including: wafer cleaning; wet dry oxidation; diffusion of dopants; metallization; wafer etching; and the use of a test station to meaure the electrical properties of the devices created.
  • 4. Master the use of a software packae to accomplish objective 3.
  • 5. Collaborate on a team project to develop prodesses used to fabrication advanced devices and/or circuits.
