Lidar accelerates hurricane recovery in the Carolinas

Hurricane Florence's slow trot over North and South Carolina in September led to inundating rain, record storm surges, and another major disaster for the Federal Emergency Management Agency (FEMA) to contend with. Facing ...

Keeping up with Moore's Law

These days, Moore's Law is not so much a scientific law as an aspiration. The notion that there is a doubling every year of the number of components that can be squeezed on to the same area of integrated circuitry was first ...

How repeated spot microdischarges damage microdevices

In microelectronics, devices made up of two electrodes separated by an insulating barrier are subject to multiple of microdischarges - referred to as microfilaments - at the same spot. These stem from residual excited atoms ...

Microelectronics

Microelectronics is a subfield of electronics. As the name suggests, microelectronics relates to the study and manufacture (or microfabrication) of very small electronic components. Usually, but not always, this means micrometre-scale or smaller,. These devices are made from semiconductors. Many components of normal electronic design are available in microelectronic equivalent: transistors, capacitors, inductors, resistors, diodes and of course insulators and conductors can all be found in microelectronic devices. Unique wiring techniques such as wire bonding are also often used in microelectronics because of the unusually small size of the components, leads and pads. This technique requires specialized equipment and is expensive.

Digital integrated circuits (ICs) consist mostly of transistors. Analog circuits commonly contain resistors and capacitors as well. Inductors are used in some high frequency analog circuits, but tend to occupy large chip area if used at low frequencies; gyrators can replace them in many applications.

As techniques improve, the scale of microelectronic components continues to decrease. At smaller scales, the relative impact of intrinsic circuit properties such as interconnections may become more significant. These are called parasitic effects, and the goal of the microelectronics design engineer is to find ways to compensate for or to minimize these effects, while always delivering smaller, faster, and cheaper devices.
