Course content

This course provides an introduction to micro- and nanofabrication, including silicon technology for fabrication of sensors and actuators. Selected semiconductor manufacturing processes in clean room, such as photolithography, etch and metallization are highlighted. Basic mechanics for design of microelectromechanical systems (MEMS) is presented, together with different principles for sensors and actuators based on piezoresistivity, electrostatics, capacitance and thermal effects. Design and fabrication of different physical sensors, such as pressure sensors and accelerometers, are given in detail.
