MEMS foundry arena gets more crowded

What is a semiconductor?
A class of materials, for instance silicon and germanium, whose electrical properties lie between those of conductors (such as copper and aluminum) and insulators (such as glass and rubber). It displays relatively high resistance in pure state and much lower resistance when it contains small amounts of certain impurities.

What does MEMS stand for?
MEMS stands for microelectromechanical systems. They are tiny mechanical devices that are built onto semiconductor chips and are measured in micrometers. They are used to make pressure, temperature, chemical and vibration sensors, light reflectors and switches as well as accelerometers for airbags, vehicle control, pacemakers and games.
