Chip makers received an ultimatum traditional development space you have less than 1 nm zngay


Chip makers received an ultimatum: traditional development space you have less than 1 nm [] wrote in the previous 40 years, Moore’s law has been already IT. However, with the development of chip technology, Moore’s law predicted the development trajectory seems to have approached the end. This means that stick to the traditional idea of chip manufacturers will be difficult. Recently, the U.S. team developed 1 nanometer transistors on the chip business is tantamount to "ultimatum". How will they redeem themselves? The following are from foreign media, compiled by Tencent Technology Developed a 1 nanometer transistor Javey and Sujay researcher Ali Desai recently, the Laurence Berkeley National Laboratory (Lawrence Berkeley National Laboratory) – a research team has successfully developed the gate (current in a transistor controlled by a gate transistor) only 1 nm, which is the smallest transistors in history. This many people are not calm, the media have not sung cries of "moore". As we all know, over the years, the development of the computer industry has always followed Moore’s law. Moore’s law states that the number of transistors in a semiconductor circuit doubles every 18-24 months. The size of the transistor is very important for the improvement of computer technology. Transistors are smaller, the number of transistors on a single chip can be more; the number of transistors on the chip, the faster the processor, the higher the efficiency. The same price of electronic products, after a lapse of 18-24 months will double. But on the other hand, if a IT company sells the same number of products as it did 18 months ago, it would have to cut its sales by half. That’s why, for decades, chipmakers have been struggling with Moore’s law, which can’t make smaller transistors, and threaten to survive. But now, it’s all about rewriting. For over 40 years, Moore’s law is always the rule IT. However, since twenty-first Century, Moore’s law seems to have a sign of slowing down. With the further development of the chip technology, Moore’s law is gradually restricted by physical laws. The industry generally believes that the 7 nanometer silicon transistor is a hurdle, once this node will encounter problems. Because once the gate silicon transistor is less than 7 nm, electrons can flow between the different transistor, this phenomenon is known as quantum tunneling effect (Quantum Tunneling), it means that the transistor may be supposed to be closed under accidental opening. But even more than 7 transistors, is still facing the problem from theory to reality. At present, the most advanced chip manufacturing process is the use of 14 nm transistor, while the use of the processor, such as’s nano transistor, such as Intel’s Cannonlake processor is expected to be launched in 2017 or 2018. IBM production of 7 nanometer test chip here to provide some reference: a hair is about 100 thousand nanometers so thick, a red blood cell diameter of 6000 nm, even a DNA chain.相关的主题文章:
