Etymology: Microelectronics is a compound built from two parts with very different histories. The "micro-" comes from Ancient Greek "mīkrós", meaning small, and it entered English as a combining form. The "electronic" half goes back to Greek "ḗlektron", amber, the yellowish fossil resin that, when rubbed, attracts light objects. Its Latin borrowing "ēlectrum" gave rise to "electricus" in New Latin, and the modern sense of electricity grew out of those early observations of static charge. "Electronic" was formed in English from "electron" plus the adjective suffix "-ic", and "microelectronic" was then built by adding "micro-" to it. The plural noun "microelectronics" names the whole field of making such tiny components. The word is a straightforward modern coinage, so its literal meaning is simply "small electrical" work, with the amber origin lying several steps back in its ancestry.
