What is MEMS?
 MEMS: Micro Electro Mechanical Systems
 Definition: systems in micro scale (10-6~10-3 m) that combine
electrical and mechanical components and are fabricated using
semiconductor fabrication techniques.
 MEMS integrates functions of sensing, actuation, computation,
control, communication, power, etc.
 Typical MEMS devices: MEMS pressure sensor, accelerometer,
microgyroscope, micromotor, resonator, valve, gear,
micromirror, optical switch, microneedle, RF capacitor, lab-onchip, etc.
 NEMS: Nano Electro Mechanical Systems (10-9~10-6 m).

Low energy consumption, high efficiency
Multi-function, intelligentized
 MEMS applications:
Automobile industry
Medical health care
Aerospace
Consumer products
RF telecommunications
Other areas
Nanotechnology
 Nanotechnology: a field of applied science and technology
whose unifying theme is the understanding and control of
matter on the atomic and molecular scale, normally 1 to 100
nanometers, and the fabrication of devices within that size
range.
 Nanotechnology is a general-purpose technology which will
have significant impact on almost all industries and all areas
of society. It can offer better built, longer lasting, cleanser,
safer and smarter products for home, communications,
medicine, transportation, agriculture and many other fields.

Low Power VLSI Design and VLSI Testing
 Modern VLSI may contain billions of transistors
 Power density is approaching that in a nuclear reactor: low
power VLSI design is a must, especially for portable electronics.
 VLSI Testing: How to quickly and thoroughly test a modern
VLSI chip with billions of transistors?
