What is MEMS?

• Micro-Electro-Mechanical Systems
• is the integration of elements, sensors,
  actuators, and electronics on a common silicon
  substrate through micro-fabrication technology, a
  manufacturing technology for making microscopic
  devices
• Other Materials used in MEMS
• Gallium Arsinide
• Titanium Nickel
• Piezoelectric Materials

How MEMS are made!

• There are three main building blocks in MEMS
• Deposition process
• The ability to deposit thin films of material
• Lithography
• is typically the transfer of a pattern to a
  photosensitive material by selective exposure to
  a radiation source such as light
• Etching Process
• Wet etching where the material is dissolved when
  immersed in a chemical solution
• Dry etching where the material is sputtered or
  dissolved using reactive ions or a vapor phase
  etchant
