What does IC do?

The working principle of the chip is that the circuit is manufactured on the surface of the semiconductor chip for calculation and processing.

Integrated circuits have two main advantages over discrete transistors: cost and performance. The low cost is due to the fact that the chip prints all of its components as a unit through photolithography, rather than making just one transistor at a time.

IC Chip (Integrated Circuit Chip) is an integrated circuit formed by a large number of microelectronic components (transistors, resistors, capacitors, etc.) placed on a plastic base to make a chip. IC chip includes wafer chip and package chip, and the corresponding IC chip production line is composed of wafer production line and package production line.

The transistor in the chip is divided into two states: on and off, usually using 1 and 0 to represent, and then passing signals and transmitting data through 1 and 0. After the chip is powered on, it will produce a startup command, and all the transistors will begin to transmit data, sending specific instructions and data out.

Extended data

Based on the number of microelectronic devices integrated on a chip, integrated circuits can be divided into the following categories:

1, Small integrated circuit (SSI English full name is Small Scale Integration) logic gate less than 10 or transistor less than 100.

2, Medium integrated circuit (MSI English full name Medium Scale Integration) logic gate 11~100 or transistor 101~1k.

3, large-scale integrated circuit (LSI English full name is Large Scale Integration) logic gate 101~1k or transistor 1,001~10k.

4, Very large scale integrated circuit (VLSI English full name is Very large scale integration) logic gate 1,001~10k or transistor 10,001~100k.

5, extremely Large Scale integrated circuit (ULSI English full name Ultra Large Scale Integration) logic gate 10,001~1M or transistor 100,001~10M.

6, GLSI (English full name Giga Scale Integration) logic gate more than 1,000,001 or transistor more than 10,000,001.

IC: Short for Integrated Circuit, an integrated circuit is a miniature electronic device or component. Using a certain process, the transistors, diodes, resistors, capacitors and inductors required in a circuit and wiring are interconnected together, made on a small or several small pieces of semiconductor chips or dielectric substrates, and then packaged in a tube shell to become a miniature structure with the required circuit functions.

First, the main work content of IC personnel is as follows:

1, the use of automatic test probe station and other equipment to complete the wafer test operation;

2, operate automatic testing, automatic sorting equipment for finished product testing operation;

3, reliability test;

4. Prepare test reports and analyze test results;

5, technical communication with chip design, chip manufacturing, chip packaging and other departments.
