  • The field of microelectronics began in 1948 when the first transistor was invented. This first transistor was a point-contact transistor, which became obsolete in the 1950s following the development of the bipolar junction transistor (BJT). The first modernday junction field-effect transistor (JFET) was proposed by Shockley (1952). These two types of electronic devices are at the heart of all microelectronic components, but it was the development of integrated circuits (ICs) in 1958 that spawned today's computer industry...

  • Microelectromechanical systems (MEMS) have played an increasingly important role in sensor and actuator applications. And its key contribution is that it has enabled the integration of multi-components (i.e., electronics, mechanics, fluidics and etc) on a single chip and their integration has positive effects upon performance, reliability and cost. Compared to conventional electrostatic, thermal or magnetic actuating schemes, piezoelectric MEMS inkjet has the advantages of lower power consumption, lower voltage operation and relatively larger driving force....

  • Within a period of a few decades, the ¯eld of materials science and engineering has emerged as a focal point for developments in virtually all areas of engineering and applied science. The study of thin film materials has been one of the unifying themes in the development of the ¯eld during this period. As understood here, the area encompasses ¯lms bonded to relatively thick substrates, multilayer materials, patterned ¯lms on substrates and free-standing ¯lms.

  • Making microsystems at a scale level of few microns is called micromachining. Micromachining is used to fabricate three-dimensional microstructures. It is the foundation of a technology called Micro-Electro-Mechanical-Systems (MEMS). MEMS usually consist of three major parts: sensors, actuators, and an associate electronic circuitry that acts as the brain and controller of the whole system.

  • The confluence of market demand for greatly improved compact power sources for portable electronics with the rapidly expanding capability of micromachining technology has made feasible the development of gas turbines in the millimeter-size range. With airfoil spans measured in 100’s of microns rather than meters, these “microengines” have about 1 millionth the air flow of large gas turbines and thus should produce about 1 millionth the power, 10-100 W.
