ECE 59500 - MEMS I: Microfabrication and Materials for MEMSLecture Hours: 3 Credits: 1
This is an experiential learning course.
CMPE Special Content Elective
Experimental Course Offered: Fall 2019
This course introduces the fundamentals of microfabrication used for wafer-scale manufacturing of Microelectromechanical Systems (MEMS). Borrowing some techniques from the integrated circuit (IC) fabrication and engineering new techniques to solve MEMS-specific challenges, MEMS microfabrication boasts an extensive toolbox employed both in research-level prototyping and in mass production in MEMS industry. The course reviews key methods for deposition, patterning, release, and packaging of MEMS devices. Considerations for benefits and levels of integration of MEMS and ICs are discussed. Micro-fabrication case studies of several MEMS devices are reviewed.
This course is the first 1-credit module in a 3-module series that runs the first five weeks of the semester.
