EEC244A – Design Of Microelectromechanical Systems (Mems)

3 units – Fall Quarter

Lecture: 3 hours

Prerequisite: EEC 140A, EEC 140B or consent of instructor

Grading: Letter; homework (10%), midterm (20%), final (35%), design project (35%).

Catalog Description:

Theory and practice of MEMS design. Micromechanical fundamentals, CAD tools, case studies. A MEMS design project is required. The designs will be fabricated in a commerical foundry and tested in course EEC244B. (Offered in alternate years)

Expanded Course Description:

During the course, the students will design and lay out their own MEMS. The weekly computer-lab sessions and most of the homework will be related to the design project. An important part of the design is a detailed test plan. After the completion of the course the designs will be fabricated in a commercial foundry. In the second course in the series (EEC 244B) the students carry out a thorough characterization of the fabricated devices.
