What does microchip mean?
A microchip is a tiny semiconductor device that contains an electronic circuit etched onto a small piece of silicon or another semiconductor material. It is the building block of many electronic devices, from calculators and phones to medical implants and vehicles. The term can also refer to a small identifying or tracking chip implanted in an animal. In ordinary speech, “chip” often means the same thing, especially in computing contexts, while “microchip” is more explicit and widely understandable. A microchip is valued not merely for its size but for the complex circuitry and processing it can contain. The word has become a familiar symbol of modern electronics, even when people cannot identify the tiny device itself. It is therefore useful both as a precise technical term and as a common expression for the small integrated components that make digital technology possible.
A tiny semiconductor device containing an integrated electronic circuit, usually fabricated on a small piece of silicon or similar material.
"The chipmaker has begun producing microchips for use in electric vehicles."
The word may also denote an identifying or tracking chip implanted in an animal or object.
To insert or implant a microchip in an animal, object, or other subject.
"The clinic microchipped the dog so that it could be identified if it went missing."
The verb is transitive and is chiefly used in contexts involving identification or tracking.
Microchips is the standard plural form. Microchip remains singular when used attributively, as in “microchip manufacturer.”
"The factory produces millions of microchips for the electronics industry."
The “micro” describes the chip's scale; its impact can be anything but small.

Where does microchip come from?
Microchip combines the prefix micro-, from Greek mikros meaning “small,” with the older English noun chip, used for a small piece or fragment. The compound arose during the development of semiconductor electronics, when increasingly small integrated circuits became central to computing. Its prefix relatives include microscope, microcosm, microorganism, and microphone, all of which ultimately draw on the Greek root for “small.”

How microchip is actually used
The term is neutral and common in technical as well as general contexts. It is especially associated with semiconductor electronics, but it is also widely used for chips implanted in animals. There are no major British and American differences in usage.
Easily confused with microchip
A microprocessor is a processor, whereas a microchip may contain a processor together with memory and other components.
In electronics, chip is a broader shorthand for a small semiconductor component, while microchip specifically identifies an integrated electronic circuit.
