EPFLx: Micro and Nanofabrication (MEMS)
Published:
Microfabrication and nanofabrication are the basis of manufacturing for nearly all modern miniaturized systems that are ubiquitously used in our daily life. Examples include computer chips and integrated sensors for monitoring our environment, cars, mobile phones, medical devices and more.
MEMS introduction and cleanroom rules
This module introduces the basics of micro-electromechanical systems (MEMS) and cleanroom fabrication.
