A major breakthrough in computing technology the birth of 1nm transistors 9c8947

A major breakthrough in computing technology sector: 1nm existing 22nm transistor transistor was born phoenix technology news Beijing on October 7th news, according to foreign media reports, today, computing technology sector has long been silent ushered in a big news. A team at Laurence Berkeley National Laboratory has broken the physical limit, reducing the most sophisticated transistor process from 14nm to 1nm.   transistor process size has been a hard indicator of computing technology progress. The smaller the transistor, the same size of the chip can be integrated more, so that the processor performance and power consumption can be a great progress. Over the years, the development of technology are in accordance with Moore’s law, that is, when the price is unchanged, the number of components can be accommodated on the integrated circuit, about every 18-24 months will be doubled, the performance will be doubled. In other words, every dollar can buy computer performance, will be more than doubled every 18-24 months. Right now, we use the mainstream chip process for 14nm, and next year, the industry will begin to develop 10nm process. But looking to the future, Moore’s law began to fail, because from the point of view of the manufacture of chips, 7Nm is the physical limit. Once the transistor size is below this figure, they will be very concentrated in the physical form, so as to produce a quantum tunneling effect, chip manufacturing challenges. Therefore, the industry generally believe that to solve this problem, we must break through the existing logic gate circuit design, so that electronic energy can continue to walk between the various logic gates. Previously, Intel and other chip giant said they will find new material to replace silicon to fabricate 7Nm transistor, now Laurence Berkeley National Laboratory, ahead of them, the 1nm transistor is made of carbon nanotubes and molybdenum disulfide (MoS2) produced. MoS2 will assume the responsibility of the original semiconductor, while the carbon nanotube is responsible for controlling the flow of electrons in the logic gates. At present, the research is still in the primary stage, after all, in the process of 14nm, a mold more than 1 billion transistors, and the transistor is reduced to 1nm, mass production difficulties too great. However, this research is still of great significance, the discovery of new materials in the future will greatly enhance the computing power of the computer. (compile Lv Jiahui)相关的主题文章:
