Miniaturization is the trend to manufacture ever-smaller mechanical, optical, and electronic products and devices. Examples include miniaturization of mobile phones, computers and vehicle engine downsizing. In electronics, the exponential scaling and miniaturization of silicon MOSFETs leads to the number of transistors on an integrated circuit chip doubling every two years, an observation known as Moore's law. This leads to MOS integrated circuits such as microprocessors and memory chips being built with increasing transistor density, faster performance, and lower power consumption, enabling the miniaturization of electronic devices.

Gordon Earle Moore was an American businessman, engineer, and the co-founder and emeritus chairman of Intel Corporation. He proposed Moore's law which makes the observation that the number of transistors in an integrated circuit (IC) doubles about every two years.
