How to write the chip, how to do it inside the chip

Chips that can write programs are: single-chip microcomputer, eeprom, eprom, just say single-chip microcomputer, you need to erase the original program before you can write a self-programmed program, the current single-chip microcomputer is encrypted, it is impossible to read the original program, if you have to read, you need to spend money to find someone to decrypt it, ** very high, and some chips can not be decrypted. Even if it is decrypted, it is a machine code that is read, and it is still incomprehensible.

As for what software and tools to use, different single-chip microcomputers are different, and the interfaces and wires are also different.

Answer hello. Chip is a general term for semiconductor component products, also known as microcircuits, microchips, and integrated circuits. Refers to a silicon wafer containing an integrated circuit, which is small in size and is often part of a computer or other electronic device.

Semiconductor is a general term for a class of materials, integrated circuits are a large collection of circuits made of semiconductor materials, and chips are products formed by different types of integrated circuits or single types of integrated circuits.

If the CPU of the processor is compared to the heart of the entire computer system, then the chipset on the motherboard is the torso of the entire body. For the motherboard, the chipset almost determines the function of the motherboard, which in turn affects the performance of the entire computer system, and the chipset is the soul of the motherboard.

All chips, lithography machines, and wafers used in the production of Chinese rare earths are not allowed to be sold in the United States, and the sales rights belong to China, otherwise, the rare earth ** will be stopped.

[呲tooth] with the special departure from the general learning

The device on the integrated circuit chip is not soldered, but engraved.

The upstream product of the semiconductor process is wafers made of high-purity silicon – the foundation of the semiconductor industry, on which integrated circuits are engraved.

First, the circuit design is done, and the designed drawings are made into a "film", that is, a mask, which is covered on the wafer. A laser is used to engrave the circuit on the wafer on the drawing. The wavelength of the laser is very short and the coherence is strong, so the transistor can be carved very small, and the main manufacturing work of integrated circuit chips lies in this.

After that, there are tape-out, dicing, packaging and so on.

You can consider making a computer, that is, to add and subtract, multiply and divide modulus, registers of various data types, such as integers or floating points, logical formula operations such as or not, and judgment loops and other controls, parentheses and the like, as well as calling program paragraphs, envelopes and the like, controlling the input and output ports and other functions, all ,-- are realized, no matter whether you use a Turing machine or what, as long as you let the program ape order the instructions of these functions, That is, to write a paragraph **, it is rich in life, and it is more than what a calculator can do, but the efficiency is worrying, but the bottom layer of the chip seems to be the circuit logic such as the NAND gate, that is, the high level plus the low level is equal to something or something, so although the chip is flat, it can be crossed from a line by arc discharge using the same rejection and different absorption that also exists in the circuit, but it will increase the complexity of the circuit and the heating delay, etc., so the CPU process is doubled, and the single-core performance is not necessarily improved much, It is difficult to greatly improve the performance by increasing the chip area by greatly increasing the etching process, but if the CPU pipeline technology is optimized and improved, it can still bring a lot of improvements.

CPU chips are laser-engraved silicon wafers.

China can't do it yet, no one knows.

The manufacturing process of chips is more complicated, so it is recommended to go to the factory to have a look.
