Tech or other science major graduate students who plan their research based on micro/nano systems approaches. Those who want to gain broad knowledge about the new micro/nano technology trends.

What it's about

Micro Electro Mechanical Systems (MEMS) has demonstrated powerful capabilities in many fields of engineering and science. MEMS-based commercial products are already in the market, replacing existing technology, or creating new possibilities. This technology is firmly based on a unique manufacturing paradigm, micromachining. Micromachining is a core technology that enables the MEMS and related new approaches in engineering and science. This course will cover the fundamental fabrication and theoretical issues of the micromachining critical in micro/nano systems applications.
