IC Substrate - The difference between chips, semiconductors and integrated circuits

What is a chip

Chips, also known as microcircuits, microchips, and integrated circuits(English: 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. It is the carrier of integrated circuit (IC), which is divided into wafers. A silicon chip is a very small piece of silicon containing integrated circuits. It is a part of a computer or other electronic equipment.

What is a semiconductor

Semiconductor (semiconductor) refers to a material whose conductivity is between a conductor and an insulator at room temperature. Semiconductors are widely used in radios, televisions and temperature measurement. For example, a diode is a device made of semiconductors. Semiconductor refers to 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 huge. Most of today's electronic products, such as computers, mobile phones, or digital tape recorders, have a very close connection with semiconductors. Common semiconductor materials include silicon, germanium, gallium arsenide, etc., and silicon is the most influential in commercial applications among various semiconductor materials. Substances exist in various forms, solid, liquid, gas, plasma, etc. We usually call materials with poor conductivity, such as coal, artificial crystals, amber, and ceramics, as insulators. Metals with better conductivity, such as gold, silver, copper, iron, tin, aluminum, etc., are called conductors. You can simply call the material between the conductor and the insulator a semiconductor.

What is an integrated circuit

Integrated circuit (integrated circuit) is a kind of miniature electronic device or component. A certain process is adopted to interconnect the transistors, resistors, capacitors and inductors and other components and wiring required in a circuit together, fabricate on a small or several small semiconductor wafers or dielectric substrates, and then package them in a package, It has become a micro structure with the required circuit functions; all of the components have been structured as a whole, making electronic components a big step towards micro miniaturization, low power consumption, intelligence and high reliability. It is represented by the letter "IC" in the circuit. The inventors of integrated circuits are Jack Kilby (integrated circuits based on germanium (Ge)) and Robert Noyth (integrated circuits based on silicon (Si)). Most applications in today's semiconductor industry are silicon-based integrated circuits. It is a new type of semiconductor device developed in the late 1950s and 1960s. It is through the semiconductor manufacturing processes of oxidation,

photolithography, diffusion, epitaxy, and aluminum evaporation, the semiconductor, resistor, capacitor and other components required to form a circuit with a certain function and the connecting wires between them are all integrated into a small piece of silicon On-chip, then solder the electronic devices packaged in a package. Its packaging shell has many forms such as round shell type, flat type or dual in-line type. Integrated circuit technology includes chip manufacturing technology and design technology, mainly embodied in processing equipment, processing technology, packaging and testing, mass production and design innovation capabilities.

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 something that is covered with a lot of small feet that you can see with the naked eye or that you can't see with your feet, but that is obviously square. However, the chip also includes a variety of chips, such as baseband, voltage conversion, and so on.

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

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

Integrated circuit refers to the active devices, passive components and their interconnections that make up a circuit are fabricated on a semiconductor substrate or on an insulating substrate together to form a structurally closely connected, 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 term for semiconductor component products. It is the carrier of integrated circuit (IC), which is divided into wafers.

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 bit of large semiconductor chip inside the integrated circuit package, that is, the die. Strictly speaking, chips and integrated circuits cannot be interchanged. Integrated circuits are manufactured through semiconductor technology, thin film technology, and thick film technology. Any circuit with a certain function is miniaturized and then made in a certain packaged circuit form, it can be called an integrated circuit. A semiconductor is a substance between a good conductor and a non-good conductor (or insulator).

Semiconductor integrated circuits include semiconductor chips and peripheral related circuits.

·Semiconductor integrated circuits·

A semiconductor integrated circuit is a combination of active components such as transistors, diodes, and passive components such as resistors and capacitors, which are interconnected according to a certain circuit and "integrated" on a single semiconductor chip to complete a specific circuit or system function.

·Semiconductor chips·Semiconductor devices that can perform certain functions by etching and wiring on semiconductor sheets. Not only silicon chips, common ones include gallium arsenide (gallium arsenide is toxic, so don’t be curious to decompose it for some low-quality circuit boards), germanium and other semiconductor materials. Semiconductors are also trendy like cars. In the 1970s, American companies such as Intel had the upper hand in the dynamic random access memory (D-RAM) market. However, because of the emergence of mainframe computers, Japanese companies were among the best in the 1980s when high-performance D-RAM was required.

Let's talk about semiconductors first

Semiconductors are talking about the simple substance of silicon. After the silicon is purified by the factory, it becomes a disc, called a wafer. PS: I remember that those brainless cultivating novels are all able to take advantage of the crystal element to increase their skills. Do you want to eat one? This one is very expensive.

Transistor

Anyone who has studied mode electricity knows that MOS tubes are produced by various ion implantation. Then the factory can form a MOS tube on the wafer by implanting various ions into the wafer.

resistance

The resistance formula is known that R is proportional to the length L and inversely proportional to the width S, so it is very simple to make resistance on the wafer. Anything that can appear on the wafer, made into a rectangle, is just a resistor. Therefore, on the wafer, there are many types of resistors to choose from. Metal resistors, POLY resistors, etc., their accuracy is different, and the magnitude of the resistance is also different.

capacitance

Two plates can be placed in parallel to form a capacitor, so this is also very easy to do. Some parasitic capacitance effects, even MOS transistors can be used as equivalent capacitances.

inductance

Inductance can also be made, but there is a problem. It consumes too much layout area to make inductance. Now tape-out (that is, the finished circuit layout is processed by the factory) is very expensive, so designers can only compromise and make inductors into slices. Outside, or think of his way. If I have to go in, I will be invited by the boss to have coffee the next day? The connection between the devices is connected by metal, and the entire chip will have multiple layers of metal.

Encapsulation

Wrap the whole carve with plastic, including silicon, implanted ions, metal, etc., to lead out the input and output pins. It's the chip you saw.
