As the name suggests, microelectronics relates to the study and manufacture (or microfabrication) of very small electronic designs and components.
These include transistors, capacitors, inductors, resistors, diodes and (naturally) insulators and conductors can all be found in microelectronic devices.
Digital integrated circuits (ICs) consist of billions of transistors, resistors, diodes, and capacitors.
As techniques have improved, the scale of microelectronic components has continued to decrease.
[2] At smaller scales, the relative impact of intrinsic circuit properties such as interconnections may become more significant.
