2, in addition to TSMC, Samsung is also an important player in the field of 5nm chip manufacturing. As a world-renowned manufacturer of electronic products, Samsung has strong research and development strength and advanced production technology. The company also has a deep accumulation in the field of chip manufacturing, and its 5-nanometer chips have been widely used in several fields. In addition, Intel as traditionalChip manufacturing giants are also actively laying out the 5-nanometer chip market.
3, TSMC 5nm and 4nm refers to the different nanoscale process nodes produced by Taiwan semiconductor manufacturing company TSMC. First, the nanoscale represents the smallest feature size in the chip manufacturing process. The 5nm process is more advanced than the 4nm process, meaning that the 5nm process can achieve higher integration, higher performance and lower power consumption. 4, TSMC, as the dominant player in the global semiconductor market, not only provides support for the 16-nanometer process production of Apple A-series processors, but also plans to launch in 2020The new technology of 10 nm is adopted. Their internal planning shows that the 5-nanometer production line will start construction in 2020 and go into mass production in 2022, while the 3-nanometer is expected to start construction in 2020 and go into mass production in 2022, with the goal of achieving full 5-nanometer and 3-nanometer processes by 2022.
1, nano refers to the characteristic size of the chip. The lowest layer of the chip is the mos tube, the smaller the feature size, the smaller the mos tube produced, which represents the coreThe more integrated the film, the lower the cost. Under the condition that the chip occupies the same area, the higher the integration, the more functional circuits can be crammed into the chip.
2, nano chip concept: 5 nm refers to the feature size of the chip, the smaller the feature size, the smaller the mos tube is manufactured, and the cost is lower. The 5-nanometer chip means that the chip is smaller, the transistors are closer together per unit area, and the power consumption is also lower. The five-nanometer concept means less energy consumption and better performance. Nanometer (symbol: nm), that is, nanometer, is a unit of measurement of length. 1 nanometer =10 to the minus 9 meters.
2, nm means 5 nanometers. Nanometer is the diameter of the laser, the smaller the laser, the more precise the circuit can be drawn, so that the number of transistors loaded in the same volume is also more. The more transistors there are, the more functions a chip can perform, so more chips can be made using the wafers to their full potential. Nanometer unit conversion: 1nm=10-9 m, symbol is nm.
3, nano chips are usually used in higher-end processors, 20 nmThe meter chip is usually used in the terminal processor, and the density of the transistor is different. In the same area, the density of the transistor on the 5-nanometer chip is larger. Transistors on 20-nanometer chips are less dense.
4. Different processors are used. The 5-nanometer chip is usually used in the higher-end processor, and the 7-nanometer chip is usually used in the terminal processor. Transistors have different densities. In the same area, the density of the transistor on the 5-nanometer chip is larger. Transistors on 7-nanometer chips are less dense. Different optimizations in terms of performance and power consumption. The 5nm chip has good performance and low power consumption. 7nm chips are a little less powerful, higher power consumption.
5, the function of more complex circuits, thereby improving the function and performance of all aspects of the chip. At the same time, the size of the components in the circuit can be reduced, so that the entire circuit power consumption is reduced. A 5-nanometer chip holds as many as 15.3 billion transistors. 5 nanometers can not be distinguished by the naked eye, in the field of electronic technology, the technical precision level is described by nanometers, so the smaller the number of nanometers, the more advanced the process and products.
6, the smaller the nano process, the better the performance. In general, the smaller the number of chip processes, the higher the transistor density and the higher the performance. For example, 7nm TSMC chips have about 100 million transistors per square millimeter, and then 5nm and 3nm chips will further increase the number of transistors per square millimeter to 71.3 billion and 500 million.
1, nm chip without lithography machine! Chinese technology companies have applied for manufacturing patents. On September 15, a patent for "direct etching method for 5-nanometer chip manufacturing" applied by a Chinese technology company was officially published. The invention relates to chip design and manufactureYes. The highlight of this invention is that without EUV lithography or DUV lithography, 5-nanometer chips can be fabricated by direct etching without the lithography process. Once the patent was published, it attracted the attention of a large number of netizens.
2, do not need EUV lithography machine, nano imprinting technology can achieve 5nm chips. Recent news reports claim that a Chinese chipmaker has successfully developed a new technology called NIL nanoimprint technology. This technology is believed to be able to bear the work of EUV lithography machines and has lower production costs. NIL (Nanoimprint Lithography is a nanoreplication technology that copies the pattern of a chip onto the surface of a silicon chip.
3, the five-nanometer chip does not need a lithography machine is true. Canon has announced that through NIL nanoimprint technology, it will be able to manufacture 5nm chips without the use of EUV lithography machines by 2025. The NIL nanoimprint technology is similar to printing technology in that the chip is manufactured by burning the circuit pattern onto a dedicated chapter, which is then imprinted onto a silicon wafer.
4, the five-nanometer chip does not need a lithography machine is not entirely accurate. Although the lithography machine is manufacturingIt plays a crucial role in microelectronic devices, but the manufacturing process of five-nanometer chips still requires the use of lithography machines or other similar devices. Lithography is one of the key tools for manufacturing microelectronic devices, which can transfer integrated circuit patterns to silicon wafers.
5, the methods of producing 5nm chips without lithography mechanism include the use of nanoimprint equipment, the use of SMIC's N1st generation process, the use of carbon nanotubes instead of silicon nanotubes, the use of electron beam lithography technology, and the use of quantum chips. Nano imprinting equipment is used. Using nanoimprint equipment to transfer the microstructure of integrated circuits onto silicon wafers, 5nm cores are manufacturedPieces. Smic's N1 process is used.
