This course is not offered in 2019.

This course introduces design and fabrication of MEMS, including topics of material properties, micro-fabrication technologies, and basic principles of MEMS sensors and actuators, and applications. The first half term covers basic microfabrication techniques and process flow, MEMS materials and their properties, structural behavior and packaging. The second half term covers different sensing and actuating working principles (i.e. electrostatic, piezoelectric, piezoresistive, thermalcapacitive, microfluidics, etc.), design and analysis. A variety of MEMS device are analyzed including inertial sensors, pressure sensors, gyroscope, optical MEMS, and bioMEMS. In addition, throughout the course, a number of real-world applications are introduced and discussed. Hands-on lab sessions in cleanroom are significant components.

  • Understand the basic principles of MEMS sensors and actuators (mechanical, electrical, piezoresistive, piezoelectric, thermal, microfluidic)
  • Understand the design considerations of basic MEMS sensors and actuators
  • Design a basic MEMS sensor and actuator device, such as an inertia sensor, and a pressure sensor
  • Design the process flow of a basic MEMS device, such as an inertia sensor (accelerometer), given a fabrication process description.
  • Understand the design constrains and the affect factors, i.e. power, speed, noise, etc.
  • Understand and familiar with the fabrication process through the hands-on activities.

Measurable Outcomes

  • Design a basic MEMS device, such as a cantilever based actuator, pressure sensor, and accelerometer
  • Design the fabrication process of a MEMS device, such as a capacitive pressure sensor or an inertia sensor
