1. Microcircuit:

Microcircuit refers to a microelectronic device that has high-density equivalent circuit elements and (or) components and can be used as an independent piece.

Microcircuits can be microorganizations or integrated (micro)circuits.

Transient X-ray and X-ray pulse irradiation will cause the electrical performance of the device to change instantaneously.

Due to the ionization effect, a photocurrent is generated in the device. The generation of photocurrent introduces additional signals to the electronic system to change its function. In severe cases, the leads of the device can be burnt and cause permanent damage.

The size of the photocurrent is related to factors such as the intensity of the ray, pulse duration, device type, bias level and load size.

Therefore, anti-transient radiation hardening is an important part of the research on anti-radiation hardening of electronic systems.

2. Integrated Circuits:

An integrated circuit is a miniature electronic device or component.

A certain process is used to interconnect the transistors, resistors, capacitors, inductors and other components and wiring required in a circuit, fabricate on a small or several small semiconductor wafers or dielectric substrates, and then package them in a package , It becomes a miniature structure with the required circuit function;

All of the components have been structured as a whole, making electronic components a big step towards miniaturization, low power consumption, intelligence and high reliability.

It is represented by the letter "IC" in the circuit.

Most applications in today's semiconductor industry are silicon-based integrated circuits.
