1.Chip concepts

Let's start by distinguishing a few basic concepts: chips, semiconductors, and integrated circuits.

Semiconductor: a material with conductive properties between conductor and insulator at room temperature. Common semiconductor materials include silicon, germanium, and gallium arsenide. Nowadays, the common semiconductor material used in chips is silicon.

Integrated circuit: a miniature electronic device or component. Using a certain process, the transistors, resistors, capacitors, and inductors required in a circuit and wiring are interconnected together, made on a small or several small semiconductor wafers or dielectric substrates, and then encapsulated in a tube housing to become a miniature structure with the required circuit function.

Chip: It is the fabrication of the transistors and other devices required for a circuit on a single piece of semiconductor (from Jeff Dahmer). Chips are the carriers of integrated circuits.

However, in a narrow sense, there is no difference between the IC, chip, and integrated circuit that we refer to every day. The IC industry and chip industry that we normally discuss refer to the same industry.

To sum it up in one sentence, a chip is a physical product obtained by designing, manufacturing, and packaging an integrated circuit using semiconductors as raw materials.

When a chip is mounted on a mobile phone, computer or tablet, it becomes the heart and soul of such electronic products.

A touch screen needs a touch chip, a memory chip to store information, a baseband chip, an RF chip, a Bluetooth chip to implement communication functions, and a GPU to take great photos ...... All the chips in a mobile phone add up to more than 100.

2.Chip classification

The way of processing, signals can be divided into analog chips, digital chips

Digital chips are those that process digital signals, such as CPUs and logic circuits, while analog chips are those that process analog signals, such as operational amplifiers, linear voltage regulators, and reference voltage sources.

Most of today's chips have both digital and analog, and there is no absolute standard as to what kind of product a chip should be classified as, but it is usually distinguished by the core function of the chip.

The following can be classified according to application scenarios: aerospace chips, automotive chips, industrial chips, commercial chips.

Chips can be used in the aerospace, automotive, industrial, and consumer sectors. The reason for this division is that these sectors have different performance requirements for chips, such as temperature range, accuracy, continuous trouble-free operation time (life), etc. As an example.

Industrial-grade chips have a wider temperature range than commercial-grade chips, and aerospace-grade chips have the best performance and are also the most expensive.

They can be divided according to the function used: GPU, CPU, FPGA, DSP, ASIC, or SoC ......
