[enterprise hotspot] new research of TSMC makes 1nm chip possible

2020-03-21

TSMC and Jiaotong University have jointly developed the world's thinnest, 0.7nm thick, ultra-thin two-dimensional semiconductor material insulator, which is expected to further develop a 2nm or even 1nm transistor channel. This month, the paper was successfully published in nature, a top international journal. With the support of the Minister of science and technology, the research team of Professor Zhang Wenhao from the Department of Electronic Physics, national Jiaotong University, in cooperation with Taiwan integrated circuit manufacturing Co., Ltd., has developed the world's thinnest two-dimensional semiconductor insulating layer with a thickness of only 0.7nm and a large area of wafer size. According to TSMC, the key lies in the major breakthrough of single crystal boron nitride technology, which is expected to be achieved in the future by This technology has further developed two or even one nanometer transistor channels.

 

At present, TSMC is promoting the mass production plan of 3nm, which refers to the transistor channel size. The smaller the channel is, the smaller the transistor size will be. In the process of continuous miniaturization, electrons will be more and more difficult to transmit, resulting in the inability of the transistor to work effectively. At present, two-dimensional semiconductor material is one of the most likely solutions to solve the bottleneck in the scientific community. The characteristics of two-dimensional semiconductor materials are very thin, and the plane structure is only one or two atom level thick. Zhang Wenhao pointed out that, however, the electrons in transmission are easy to be affected by the environment, so an insulating layer is needed to block the interference. At present, most of the insulating layers used in semiconductors are oxides. Generally, it is very difficult to achieve less than 5 nm, which can not be less than 1 nm. The team has developed a single crystal Boron nitride growth technology, successfully achieved 0.7 nanometer thickness of insulation layer.

 

Chen zean, technical director of TSMC, the first author of the paper, is a doctor of Chemistry Department of Qingda. He said that single crystal means a single crystal arranged in order. Single crystal is more helpful for the future semiconductor structure, because assuming that the insulating layer is not a single crystal structure, there will be many defects in the middle. The resistance may be affected by defects when passing through, resulting in poor efficiency, which has been confirmed by experiments More research is needed in the future. Chen zean said that in the past, the scientific community believed that single crystal growth was unlikely to occur on copper, but the research team found in the experiment that boron nitride grew in the same direction within the micron unit range, and arranged a single crystal. Therefore, by analyzing this tiny area, adjusting the experimental parameters and selecting materials, we have successfully overcome the obstacles. We can not only grow single crystal, but also achieve a large area of two inches The size of the wafer.

 

Li Lianzhong, director of TSMC, once a researcher of the former branch of the Chinese Academy of Sciences, said that after basic research, TSMC research team found problems and breakthrough possibilities, cooperated with the chemical vapor deposition Laboratory of Jiaotong University, and let boron nitride single crystal grow on copper. AS PCB board mufacturer, we are glad to share this industry news to you, and hope we can be your China PCB munufacturer. As a channel to protect two-dimensional semiconducting materials, at present, it is impossible to explain the mass production time, and there are many key technologies to break through, For example, metal contact and component optimization, but it will help to reduce the size of transistors in the future.
