                   What is MEMS?
q Go light, go fast, go small
q Size does matter: SMALL, SMALLER, SMALLEST

           VLSI                             MEMS

   Intel Core i7-980X Processor
                                    MEMS Digital Micromirror Device
1.17 billion transistors in 248 mm2
                    What is MEMS?
q MEMS: Micro Electro Mechanical Systems

q Definition: systems in micro scale (10-6~10-3 m) that combine
  electrical and mechanical components and are fabricated using
  semiconductor fabrication techniques.

q MEMS integrates functions of sensing, actuation, computation,
  control, communication, power, etc.

q Typical MEMS devices: MEMS pressure sensor, accelerometer,
  microgyroscope, micromotor, resonator, valve, gear,
  micromirror, optical switch, microneedle, RF capacitor, lab-on-
  chip, etc.

q NEMS: Nano Electro Mechanical Systems (10-9~10-6 m).

“LambdaRouter” optical switch (Lucent)    GeneChip DNA chip (Affymetrix)
                       Why MEMS?
q Advantages of MEMS:
  üLow cost
  üSmall size, low weight, high resolution
  üLow energy consumption, high efficiency
  üMulti-function, intelligentized

q MEMS applications:
  üAutomobile industry
  üMedical health care
  üConsumer products
  üRF telecommunications
  üOther areas
q 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
q 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.
