As a semiconductor person, selling or purchasing electronic components, do you really know what chips, semiconductors and integrated circuits are? Do you know the relationship and difference between them?

1. What is a chip

Chip, also known as microcircuit (microcircuit), microchip (microchip), integrated circuit (integrated circuit, IC), refers to a silicon chip containing an integrated circuit, which is small in size and is often part of a computer or other electronic equipment.

Chip is the general term for semiconductor component products, which is the carrier of integrated circuit (IC, integrated circuit), which is divided into wafers.

A silicon wafer is a tiny piece of silicon that contains integrated circuits that are part of a computer or other electronic device.

2. What is a semiconductor

Semiconductor (semiconductor) refers to a material whose electrical conductivity is between that of a conductor and an insulator at room temperature. For example, a diode is a device made of semiconductors. A semiconductor is a material whose conductivity can be controlled, ranging from insulators to conductors.

Whether from the perspective of technology or economic development, the importance of semiconductors is very huge. Most of today's electronic products, such as computers, mobile phones or digital recorders, are closely related to semiconductors. Common semiconductor materials include silicon, germanium, gallium arsenide, etc., and silicon is the most influential one in commercial applications among various semiconductor materials.

Matter exists in various forms, such as solid, liquid, gas, plasma, etc. We usually call materials with poor conductivity, such as coal, artificial crystals, amber, ceramics, etc., as insulators. And the metals with better conductivity such as gold, silver, copper, iron, tin, aluminum, etc. are called conductors. A material between a conductor and an insulator can simply be called a semiconductor


3. What is an integrated circuit

An integrated circuit is a miniature electronic device or component. Using a certain process, components and wirings such as transistors, resistors, capacitors and inductors required in a circuit are interconnected, fabricated on a small or several small semiconductor wafers or dielectric substrates, and then packaged in a package. , become a miniature structure with the required circuit functions; in which all components have been formed into a whole in structure, making electronic components a big step towards miniaturization, low power consumption, intelligence and high reliability. It is represented by the letters "IC" in the circuit.

The inventors of integrated circuits are Jack Kilby (germanium (Ge) based integrated circuits) and Robert Noyce (silicon (Si) based integrated circuits). Most applications in the semiconductor industry today are silicon-based integrated circuits.

The integrated circuit is a new type of semiconductor device developed in the late 1950s and 1960s. It is a semiconductor manufacturing process such as oxidation, photolithography, diffusion, epitaxy, and aluminum evaporation, which integrates semiconductors, resistors, capacitors and other components required to form circuits with certain functions and the connecting wires between them in a small piece of silicon. on-chip, and then solder the electronics packaged in a package. Its encapsulation shell has various forms such as round shell type, flat type or dual in-line type.

Integrated circuit technology includes chip manufacturing technology and design technology, mainly reflected in processing equipment, processing technology, packaging and testing, mass production and design innovation capabilities.

4. What is the difference between a chip and an integrated circuit?

The emphasis to be expressed is different.

A chip is a chip, which generally refers to the thing you can see with the naked eye that is covered with a lot of small feet or the feet are invisible, but obviously square. However, the chip also includes a variety of chips, such as baseband, voltage conversion, and so on.

The processor emphasizes more on function, which refers to the unit that performs processing, which can be said to be MCU, CPU, etc.

The range of integrated circuits is much wider. Integrating some resistors, capacitors and diodes together is an integrated circuit. It may be an analog signal conversion chip or a logic control chip, but in general, this concept is more biased towards bottom stuff.

Integrated circuit refers to the active devices, passive components and their interconnections that make up the circuit are fabricated together on a semiconductor substrate or an insulating substrate to form a closely related, internally related instance electronic circuit. It can be divided into three main branches: semiconductor integrated circuits, film integrated circuits, and hybrid integrated circuits.

Chip (chip) is the general name of semiconductor component products, which is the carrier of integrated circuit (IC, integrated circuit), which is divided into wafers.

5. What is the relationship and difference between semiconductor integrated circuits and semiconductor chips?

Chip is an abbreviation of integrated circuit. In fact, the real meaning of the word chip refers to a little large semiconductor chip inside the integrated circuit package, that is, the die. Strictly speaking, chips and integrated circuits are not interchangeable. Integrated circuits are manufactured through semiconductor technology, thin-film technology and thick-film technology. Any circuit that miniaturizes a certain function and is made in a certain packaged circuit form can be called an integrated circuit. A semiconductor is a substance between a good conductor and a bad conductor (or insulator).

Semiconductor integrated circuits include semiconductor chips and peripheral related circuits.

Semiconductor integrated circuit

Semiconductor integrated circuits are transistors, diodes and other active components and resistors, capacitors and other passive components, according to a certain circuit interconnection, "integrated" on a single semiconductor wafer, so as to complete a specific circuit or system function.

A semiconductor device that can achieve a certain function is made by etching and wiring on the semiconductor sheet. Not only silicon chips, but also common ones include gallium arsenide (gallium arsenide is toxic, so some inferior circuit boards should not be curious to decompose it), germanium and other semiconductor materials.

Semiconductors are also trendy like cars. In the 1970s, American companies such as Intel dominated the dynamic random-access memory (D-RAM) market. But in the 1980s when high-performance D-RAM was required due to the emergence of mainframe computers, Japanese companies came out on top.
