'Microelectronics' is a subfield of
electronics. Microelectronics, as the name suggests, is related to the study and manufacture of electronic components which are very small. These devices are made from
semiconductors using a process known as
photolithography. 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.
Digital
integrated circuits 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.
As techniques improve, the size of microelectronic components continue to decrease. At smaller scales, the effects of minor circuit elements such as interconnections may become more important. 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.
