1.? At present, the limit of the chip manufacturing process has reached about 7 nanometers (nm). This means that the transistor size on the chip has been reduced to the size of 7 nanometers.
This limit size is determined by physical limitations and technical challenges. With the continuous development of science and technology, people have a constant pursuit of the ultimate size of the chip manufacturing process. At present, scientists and engineers are researching and developing more advanced manufacturing processes to achieve smaller sizes of chips. For example, it is predicted that a 3-nanometer chip manufacturing process may be achieved in the future. This will require more sophisticated equipment and technology, as well as greater process control capabilities. Therefore, the ultimate size of the chip manufacturing process is an area of constant advancement and exploration that will continue to challenge smaller sizes.
At present, the limit of the chip manufacturing process has reached the 1nm level. This is because with the continuous progress of science and technology, the manufacturing process is also constantly improving and innovating. However, reaching this limit is not easy, and many technical difficulties need to be overcome, such as lithography technology, materials engineering, and so on. In addition, with the continuous improvement of the chip manufacturing process, the performance of the chip will also be further improved, thus promoting the development of science and technology.
That's 1nm. The reason why 1 nanometer is the limit of silicon-based chips is mainly based on two considerations:
First, the size of silicon atoms. The manufacturing process of the chip is to inject transistors into the silicon-based material, the more transistors the stronger the performance, want to improve the chip process, it is necessary to increase the number of transistors per unit chip area.
Second, tunneling effect.
The so-called tunneling effect is simply a phenomenon in which microscopic particles can pass through obstacles.
